This commit migrates the test_srp_many_services_mtu_check.py from
tests/scripts/thread-cert to the Nexus test framework.
The new test, tests/nexus/test_srp_many_services_mtu_check.cpp,
verifies that the SRP client correctly handles and splits SRP Update
messages when registering a large number of services that exceed
the IPv6 MTU size (1280 bytes).
Changes:
- Added tests/nexus/test_srp_many_services_mtu_check.cpp.
- Updated tests/nexus/CMakeLists.txt to include the new test.
- Removed tests/scripts/thread-cert/test_srp_many_services_mtu_check.py.
This commit stabilizes the Nexus reed_address_solicit_rejected test by
increasing the wait time for network data synchronization from 5 seconds
to 15 seconds.
The test was occasionally failing because the 5-second wait was
sometimes insufficient for the REED's service registration to reach the
leader and for the updated network data to be broadcast back to the
REED. Increasing the delay to 15 seconds provides more robust buffer for
these network events.
Verified by running the test 50 times in a loop without failures.
This commit migrates the `test_mle_msg_key_seq_jump.py` cert test to the
Nexus simulation framework.
The new Nexus test `test_mle_msg_key_seq_jump.cpp` verifies that nodes
can correctly handle jumps in the MLE key sequence and stay attached to
the network. It covers scenarios like child triggering key sequence
updates via Child Update Request and routers propagating key sequence
updates.
The original Python test script is removed as its functionality is now
fully covered by the new Nexus test.
This commit migrates the 'test_srp_client_change_lease.py' cert test
to the Nexus simulation framework.
The new Nexus test ('test_srp_client_change_lease.cpp') verifies:
- SRP registration with default lease and TTL.
- Updating the lease interval and ensuring it is reflected in SRP
Update messages.
- Updating the TTL and ensuring it is reflected in SRP Update
messages.
- Setting the TTL to 0 and ensuring the lease interval is used as
the TTL in SRP Update messages.
The original Python test script is removed as its functionality is
now fully covered by the new Nexus test.
This commit stabilizes the Nexus SRP auto-start test by increasing
the synchronization wait time from 20 seconds to 30 seconds.
The test was occasionally failing in the Nexus environment because
the 20-second wait was sometimes insufficient for the SRP server
registration to fully propagate through the network data and for
the SRP client to process the update and complete its server
selection. Increasing the wait time to 30 seconds provides a more
robust buffer for these network synchronization events.
Verified by running the test 100 times in a loop without failures.
This commit migrates the `test_ipv6_fragmentation.py` cert test to the
Nexus simulation framework.
To support this migration, the Nexus core configuration was updated to
enable IPv6 fragmentation (`OPENTHREAD_CONFIG_IP6_FRAGMENTATION_ENABLE`).
The new Nexus test `test_ipv6_fragmentation.cpp` covers the validation
of IPv6 fragmentation and reassembly. It sends large ICMPv6 Echo
Requests exceeding the 1280-byte MTU between a Leader and a Router:
- 1952 bytes payload from Leader to Router
- 1831 bytes payload from Router to Leader
The original Python test script is removed as its functionality is now
fully covered by the new Nexus test.
This commit updates the `RouterIdSet` class, renaming it to
`RouterIdMask` and expanding it to encapsulate both the router ID
sequence number and the bitmask. This allows simplifying the
definition of `ThreadRouterMaskTlv` and `RouteTlv`.
This commit simplifies the `TimeParameterTlv` implementation by
defining a `TimeParameterTlvValue` and using the `SimpleTlvInfo`
template to define `TimeParameterTlv`.
This commit migrates the SRP auto-start test from the Python-based
thread-cert test suite to the Nexus C++ test framework.
The new Nexus test replicates the logic of the original Python test:
- Forms a network with four router nodes.
- Verifies SRP client auto-start upon server discovery in netdata.
- Tests selection priority between multiple unicast and anycast
SRP servers.
- Verifies selection based on anycast sequence numbers.
- Tests selection of specific unicast addresses published in
Service Data.
- Confirms automatic failover and client stop/restart.
The original Python test file is removed as it is now covered by
the Nexus test suite.
This commit migrates the functionality of
tests/scripts/thread-cert/test_netdata_publisher.py to a new Nexus
test tests/nexus/test_netdata_publisher.cpp.
The new Nexus test covers:
- DNS/SRP Anycast entries (equal and different version numbers).
- DNS/SRP Unicast entries (service data and server data).
- Displacement of server data unicast by anycast entries.
- Publisher preference logic for DNS/SRP services.
- On-mesh prefix publisher preference and replacement.
- External route publisher preference and replacement.
Other changes:
- Add netdata_publisher to tests/nexus/CMakeLists.txt.
- Add netdata_publisher to default tests in tests/nexus/run_nexus_tests.sh.
- Remove the old tests/scripts/thread-cert/test_netdata_publisher.py.
This commit migrates the cert test script to the Nexus simulation
framework.
The new Nexus test covers:
- Initial key sequence counter and default key switch guard time.
- Dynamic updates of the key rotation time via Operational Dataset
and verification of the 93% guard time calculation rule.
- Automatic key rotation after the rotation time interval expires.
- Verification that the key switch guard time correctly prevents
nodes from updating their key sequence counter prematurely when
receiving MLE messages with a higher sequence.
- Continued communication (ICMP Echo) between nodes even when key
sequences are temporarily mismatched due to the guard timer.
The original Python test script is removed as its functionality is
now fully covered by the new Nexus test.
This commit fixes an intermittent failure in the Nexus test
'dns_client_config_auto_start'. The test was occasionally failing
because the REED node was not upgrading to the Router role within
the previous 15-second stabilization period.
The Router role transition can take up to 120 seconds due to the
default 'ROUTER_SELECTION_JITTER' parameter. This commit increases
'kStabilizationTime' to 200 seconds to ensure the node has ample
time to become a router before the test proceeds to verify its
DNS configuration.
Make `otPlatLogOutput()` `OT_TOOL_WEAK` in `cli_logging.cpp` so that
applications can provide their own strong definition to customize
instance-aware log output behaviour.
This commit migrates the 'test_mac_scan.py' cert test to the Nexus
simulation framework.
The new Nexus test 'test_mac_scan.cpp' verifies the IEEE 802.15.4
Active Scan (MAC scan) functionality. It forms a simple network
consisting of a Leader and a Router and performs an active scan
from the Leader to ensure it correctly discovers the Router's
beacon.
The original Python test script is removed as its functionality is
now fully covered by the new Nexus test.
This commit migrates the dns_client_config_auto_start test from the
thread-cert Python-based test framework to the Nexus C++ simulation
framework.
The new Nexus test (test_dns_client_config_auto_start.cpp) verifies:
- DNS client uses the SRP server address automatically when no
explicit config is set.
- Explicitly set DNS config takes precedence over auto-discovered
SRP server address.
- Clearing an explicit DNS config allows the client to fall back to
the auto-discovered SRP server address.
- DNS client updates its default config when the SRP server changes.
Changes:
- Added tests/nexus/test_dns_client_config_auto_start.cpp
- Updated tests/nexus/CMakeLists.txt to build the new test
- Updated tests/nexus/run_nexus_tests.sh to include it in default
- Removed tests/scripts/thread-cert/test_dns_client_config_auto_start.py
This commit migrates the functional test for child supervision from
the thread-cert Python-based framework to the Nexus framework.
The original test in 'tests/scripts/thread-cert/test_child_supervision.py'
has been removed and replaced with a C++ implementation in
'tests/nexus/test_child_supervision.cpp'.
The new Nexus test covers:
- Verification of initial child supervision interval on parent and child.
- Dynamically updating the supervision interval and check timeout.
- Behavior when supervision messages are blocked (child detaching).
- Verification of connectivity when child supervision is disabled.
- Handling of zero supervision interval.
'tests/nexus/CMakeLists.txt' is updated to include the new test.
This commit migrates the 'test_reed_address_solicit_rejected.py' test
from the thread-cert suite to the Nexus test framework.
The new Nexus test 'test_reed_address_solicit_rejected.cpp' covers:
- Verification that a REED node can successfully register a service and
receive the corresponding Service ALOC (0xfc10).
- Verification that when a REED node's attempt to upgrade to a router
is rejected by the Leader, it correctly remains a child while
maintaining its Service ALOC.
The original Python script is removed as its functionality is now
fully covered by the Nexus implementation.
This commit migrates the functionality of the Python-based certification
test 'test_br_upgrade_router_role.py' to a new Nexus-based C++ test
'test_br_upgrade_router_role.cpp'.
The test verifies that Border Routers (BRs) providing IP connectivity
are eligible to request a router role upgrade even when the active
router count already meets the 'router_upgrade_threshold'.
Key test steps:
- Set router upgrade threshold to 2.
- Ensure three BRs remain in child role when 2 routers already exist.
- Verify BRs upgrade to router role when they provide external routes
or prefixes, up to the limit of 2 BR routers.
- Verify that a third BR providing external routes remains a child.
- Verify that removing a route from one BR router triggers the child BR
to upgrade to a router.
The Python test is removed as it is now covered by the Nexus test.
Set the RSSI field in simulated MAC ACK frames in nexus_core.cpp.
Previously, the simulator did not populate the mRssi field in the
mInfo.mRxInfo structure of simulated ACK frames passed to
otPlatRadioTxDone. This caused OpenThread to ignore the RSSI of ACKs,
preventing the parentRss average from updating on successful data polls
from Sleepy End Devices (SEDs).
Now, the RSSI from the parent to the child is calculated using the radio
model and clamped to int8_t before being assigned to the ACK frame.
This commit migrates the test for zero-length external routes from a
Python script to the Nexus test framework. The original test was
test_zero_len_external_route.py in tests/scripts/thread-cert.
The new Nexus test test_zero_len_external_route.cpp replicates the
original test scenario:
- Forms a network with a Leader and two Routers.
- Verifies that adding a zero-length external route "::/0" on a Router
allows routing to a manually added IPv6 address on that Router.
- Verifies that explicit external routes are preferred over on-mesh
prefixes that have the default route flag set.
- Verifies that removing the external route causes traffic to be
re-routed (and in this case, fail as intended when the destination
is moved).
- Verifies that moving the address to another Router with a default
route flag allows successful routing.
This commit also fixes a bug in Core::SendAndVerifyEchoRequest in
nexus_core.cpp where the ICMP handler was not always unregistered,
especially when failures occurred. This fix ensures that subsequent
handler registrations in the same process do not fail with
kErrorAlready.
Migrating to Nexus provides faster execution and better integration with
the core OpenThread codebase.
This commit migrates the `test_ipv6_source_selection.py` cert test to
the Nexus simulation framework.
To support this migration, the Nexus framework was extended to allow
verifying the local (source) address on which an ICMP Echo Reply is
received. This is achieved by adding an overload to
`SendAndVerifyEchoRequest` that accepts an expected source address.
The new Nexus test `test_ipv6_source_selection.cpp` covers the
following scenarios:
- RLOC source for RLOC destination
- ML-EID source for ALOC destination
- ML-EID source for ML-EID destination
- Link-local source for Link-local destination
- ML-EID source for Realm-local multicast destination (ff03::1)
- GUA source for GUA destination
- GUA source for external address (via default route)
The original Python test script is removed as its functionality is now
fully covered by the new Nexus test.
Refine the event suppression logic in nexus_core.cpp when handling
NeighborTable::kChildRemoved events.
Previously, any valid neighbor found would suppress the event. Now, it
only suppresses the event if the node is found in the Router table.
This ensures that removal events for Sleepy End Devices (SEDs) are not
suppressed, allowing the link to disappear in the visualizer as
expected.
This commit fixes a compiler warning in nexus_radio.cpp where the
aFrame parameter in otPlatRadioTransmit was considered unused in
non-debug builds. The variable is only used within an OT_ASSERT.
Using OT_UNUSED_VARIABLE is the standard OpenThread pattern to
address unused parameters and ensure clean builds across different
compilers and build configurations.
This commit migrates the certification test for router downgrade on
security policy change from a Python script to the Nexus test framework.
The original test was test_router_downgrade_on_sec_policy_change.py in
tests/scripts/thread-cert.
The new Nexus test test_router_downgrade_on_sec_policy_change.cpp
replicates the original test scenario:
- Forms a network with a Leader and a Router.
- Verifies that both nodes are in the expected router/leader roles.
- Changes the security policy to disable 'R' bit (routers) and sets the
version threshold to 7.
- Verifies that the Leader and Router do not immediately downgrade,
respecting the mandatory 10-second delay.
- Verifies that restoring the original security policy before the
timeout cancels the pending downgrade.
- Verifies that re-applying the security policy change leads to both
nodes eventually downgrading to the detached state once the version
threshold and router disable flags are propagated and the timer
expires.
Migrating to Nexus provides faster execution using virtual time and a
more integrated environment for debugging core Thread logic.
This commit addresses intermittent failures in Nexus tests 1_4_DNS_TC_1,
1_4_DNS_TC_5, 1_4_PIC_TC_1, 1_4_PIC_TC_3, and 1_4_PIC_TC_4.
The issue was caused by the 'ed1' node occasionally upgrading its role
from an End Device to a Router. When 'ed1' became a router, it would
sometimes use its Routing Locator (RLOC) as the source address for DNS
queries, whereas the verification scripts expected its Mesh Local
Endpoint Identifier (MLEID), leading to packet verification failures.
To resolve this, 'ed1' is now explicitly joined as a Full End Device
(FED) using 'Node::kAsFed' instead of the default Full Thread Device
(FTD) mode. This prevents 'ed1' from becoming a router and ensures it
maintains its End Device role throughout the test, providing stable
addressing for verification.
This commit migrates the dataset_updater functional test from the
Python-based thread-cert framework to the Nexus simulation framework.
Nexus provides faster and more scalable network simulations within a
single process using virtual time.
The new test_dataset_updater.cpp covers:
- Network formation and child joining (MED and SED).
- Channel updates initiated by Leader and Router using DatasetUpdater.
- Dataset update overrides between nodes.
The legacy tests/scripts/thread-cert/test_dataset_updater.py is removed
as it is now redundant.
This commit adds a new Nexus test to verify that a Sleepy End Device
(SED) correctly informs its previous parent after reattaching to a new
parent. This replicates the functionality of the now-deleted
test_inform_previous_parent_on_reattach.py script.
The test scenario involves:
- Forming a network with a Leader and a Router.
- Attaching a SED to the Leader.
- Simulating a link failure between the SED and Leader while allowing
communication between the SED and Router.
- Verifying that the SED reattaches to the Router.
- Confirming that the SED sends an empty IPv6 message (Next Header 59)
to the Leader's RLOC to inform it of the change.
- Ensuring the SED is successfully removed from the Leader's child
table.
Migrating this test to Nexus allows for faster execution using virtual
time and single-process simulation.
The following SRP test scripts in tests/scripts/thread-cert are
redundant as their functionality is now covered by the Nexus test
framework certification suite (test_1_3_SRP_TC_*):
- test_srp_register_single_service.py: Covered by Nexus
test_1_3_SRP_TC_1.
- test_srp_lease.py: Covered by Nexus test_1_3_SRP_TC_3 (service
lease) and test_1_3_SRP_TC_4 (key lease).
- test_srp_name_conflicts.py: Covered by Nexus test_1_3_SRP_TC_2.
- test_srp_auto_host_address.py: Covered by Nexus test_1_3_SRP_TC_13.
- test_srp_sub_type.py: Covered by Nexus test_1_3_SRP_TC_15.
Nexus tests are preferred as they run in a single process using
virtual time, making them faster and more reliable than the
multi-process simulation scripts.
This commit adds support for building the Nexus simulator for
WebAssembly (WASM) using the Emscripten toolchain. This enables the
simulator to run in a web browser environment with a JavaScript-based
control interface and visualization.
Key implementation details:
- Introduced `nexus_wasm.cpp` which defines Emscripten bindings (using
Embind) for core simulation controls, including stepping time,
node creation, topology orchestration, and state manipulation.
- Implemented a `WasmObserver` and a global event queue to capture
simulation events (node state changes, link updates, packet events)
and expose them to JavaScript via a polling mechanism (`pollEvent`).
- Updated the CMake build system to support the `EMSCRIPTEN` platform,
configuring specific linker options for ES6 module export,
modularization, and memory growth.
- Enhanced `build.sh` to allow targeting WASM via `emcmake`.
- Guarded file-system-dependent operations in `nexus_pcap.cpp` and
adjusted `nexus_core.cpp` to handle WASM-specific constraints where
standard I/O or multiple observers might not be applicable.
- Added `test_wasm_bindings.mjs`, a Node.js-based smoke test that
verifies the integrity of the WASM bindings and event pipeline.
- Integrated `nexus-wasm-tests` into the GitHub Actions workflow to
ensure continuous verification of the WASM build and functionality.
This commit introduces a mechanism to temporarily override the log
level. The `Instance` class now provides `OverrideLogLevel()` and
`RestoreLogLevel()` methods. When an override is active, the
effective log level is the maximum of the original user-set level and
the override level. If `SetLogLevel()` is called while an override is
active, it updates the original level and the effective level is
recomputed.
This ensures that log messages are generated only when needed,
without permanently losing the user's original log level
configuration.
The feature is controlled by the new configuration macro
`OPENTHREAD_CONFIG_LOG_LEVEL_OVERRIDE_ENABLE`.
A new Nexus unit test `test_log_override.cpp` is added to validate
the behavior of these new feature.
The following test scripts in tests/scripts/thread-cert are now
redundant as their functionality is sufficiently covered by the Nexus
test framework:
- test_detach.py: Covered by Nexus MLE synchronization and parent
selection tests.
- test_router_upgrade.py: Covered by 5.1.x Nexus router attachment
tests.
Nexus tests are preferred for these scenarios as they execute in a
single process using virtual time, providing faster and more reliable
verification than the traditional multi-process simulation scripts.
Added `Core::AllowLinkBetween()` and `Core::UnallowLinkBetween()`
helper methods to the Nexus test platform. These methods simplify
establishing bidirectional links between nodes in simulation tests by
handling the reciprocal `AllowList()` calls in a single step.
Updated various Nexus test cases to utilize these new helpers,
replacing manual bidirectional `AllowList()` calls. This change
reduces verbosity and ensures consistency in how links are established
in the test topology.
This commit introduces `AnswerBuilder` class to track and manage
Network Diagnostic answer messages. This class is used when the
response to a query requires multiple CoAP answer messages. It
automatically manages the inclusion of the Query ID and the Answer
TLVs(providing message indexing and "more-to-follow" flags) in each
allocated answer message, while maintaining all answer messages in a
queue. The `NetworkDiagnostic::Server` is updated to use the
`AnswerBuilder`, simplifying the logic for preparing and sending
answers.
The `AnswerBuilder` class is added in a new header file
`network_diagnostic_types.hpp` to allow for its reuse by other
modules in the future.
This commit introduces gRPC support to the Nexus simulator, enabling
remote control and monitoring of simulations. This infrastructure allows
external tools and visualizers to interact with the simulated network
in real-time.
Key changes:
- Defined `simulation.proto` providing the `NexusService` definition for
simulation control and event streaming.
- Implemented `GrpcServer` in `nexus_grpc.cpp` which functions as a
Nexus simulation observer, pushing events to connected clients.
- Added RPCs for dynamic node creation, position updates, node state
control, and network orchestration (forming and joining).
- Implemented a real-time event stream that includes node state changes,
link updates, and packet captures (with basic protocol decoding).
- Introduced `nexus_native.cpp` as an entry point for a persistent
simulation server that can be controlled via gRPC.
- Updated `Core` and `Observer` interfaces to support a list of
concurrent observers instead of a single instance.
- Enhanced the CMake build system to optionally find and link against
gRPC and Protobuf, including automatic source generation.
- Updated CI (GitHub Actions) to include build and test steps for the
new gRPC functionality.
- Added comprehensive unit tests in `test_grpc.cpp` to verify all
exposed gRPC service methods.
This commit updates `CslClockAccuracyTlv` to use the `SimpleTlvInfo`
and a separate `CslClockAccuracyTlvValue` class. This change
simplifies how the TLV is appended to and read from messages
by leveraging the `Tlv::Append<TlvType>` and `Tlv::Find<TlvType>`
helper methods (avoiding the use of `FindTlv()`).
This commit removes the redundant `multiple-instance` job from the
`simulation-1.1.yml` workflow. This job was used to run Thread 1.1
certification tests with `OT_MULTIPLE_INSTANCE=ON`.
The job is being removed to streamline the CI process and reduce
redundant test coverage, as multiple-instance configurations are
sufficiently covered in other workflow files. The dependency list
for the coverage collection job is also updated to reflect this
removal.
The previous logic for suppressing CHILD_REMOVED events was flawed. It
checked if the neighbor was not in the child table. However, since the
callback is triggered after the child is removed, it was always false,
leading to false suppression for all removed children.
This caused the parent node to never emit "link removed" events to the
UI when children detached, leading to inconsistent link states (dashed
lines) when only one direction was active.
This fix updates the logic to check if a neighbor entry exists in the
neighbor table with an established link (kStateValid). This ensures we
only suppress the event when the child has successfully transitioned to
a router role and established a valid link.
This commit updates `Mle::SendMulticastAdvertisement()` to verify
that the router role is allowed by calling `IsRouterRoleAllowed()`
before proceeding to send the multicast MLE advertisement.
This commit introduces the `SimulationObserver` interface and integrates
it into the Nexus core simulation logic. This allows external systems to
observe node state changes, link updates, and packet events in real-time.
Key changes:
- Defined `SimulationObserver` interface to handle node state changes,
link updates, packet events, and event clearing.
- Added `SetObserver` and `GetObserver` methods to the `Core` class.
- Implemented `Core::HandleNeighborTableChanged` to notify the observer
of neighbor additions and removals.
- Implemented `Core::HandleStateChanged` to track node role transitions
and parent changes, updating links accordingly.
- Integrated packet event notification in `Core::ProcessRadio`,
including basic destination node ID resolution for unicast frames.
- Added `Core::SetNodeEnabled` to allow enabling or disabling Thread and
MLE on specific nodes at runtime.
- Updated `Core::Reset` to clear events via the observer.
- Increased `OPENTHREAD_CONFIG_MAX_STATECHANGE_HANDLERS` to accommodate
the new nexus state change handler.
- Added `mLastParentId` to `Node` class to correctly manage link updates
during parent switches or detachment.
RFC 8200 states that the Hop-by-Hop Options header MUST be the first
extension header and can only occur once in a packet. This commit
updates HandleExtensionHeaders to enforce this rule.
This fix prevents a potential infinite loop or exponential growth of
messages when multiple Hop-by-Hop headers (each containing an MPL
option) are processed. Previously, each MPL option could trigger its
own retransmission, and if these options were evicted from the MPL
SeedSet, they would be re-processed as new messages upon loopback,
leading to exponential growth and eventually a timeout.
This commit adds a new RadioModel class to simulate wireless propagation
characteristics between Nexus nodes. It implements a simple path-loss
model based on node distance to calculate RSSI.
Key changes include:
- Added RadioModel with CalculateRssi and ShouldDropPacket methods.
- Integrated RSSI calculation into the Core radio processing logic.
- Implemented packet dropping for signals below -100 dBm sensitivity.
- Added nexus_radio_model.cpp to the build system.
This commit introduces a new member variable `mRouterRoleAllowed` in
the `Mle` class to cache the evaluation of whether the device is
currently permitted to operate as a router.
Previously, the `IsRouterEligible()` method evaluated several
conditions (e.g., `IsFullThreadDevice()`, `mRouterEligible` config,
and various fields in `SecurityPolicy`) every time it was called.
Since this method is invoked frequently across different `Mle`
operations, re-evaluating these conditions repeatedly was
inefficient.
The new `mRouterRoleAllowed` variable caches the final computed
result. It is updated via the `UpdateRouterRoleAllowed()` method
whenever any underlying input changes, such as:
- `Mle` starting.
- Configuration parameter updates (e.g., `SetRouterEligible()`).
- Security policy changes from the `KeyManager`.
This change centralizes the logic for handling role permission updates
into a single location (`UpdateRouterRoleAllowed()`). By
consolidating the actions taken when the allowed state changes, the
codebase is cleaner and easier to maintain and update.
It also provides a clearer conceptual distinction between the user's
router configuration (`mRouterEligible`) and the effective state
used by the device.
This commit moves the TREL configuration from the build script to the
nexus-config header file. This ensures that TREL is consistently enabled
for all nexus builds and simplifies the build script.
Specifically:
- Added OPENTHREAD_CONFIG_RADIO_LINK_TREL_ENABLE to
tests/nexus/openthread-core-nexus-config.h.
- Removed OT_TREL from tests/nexus/build.sh and simplified the build
options.
This commit moves the `OPENTHREAD_CONFIG_MULTIPLE_INSTANCE_ENABLE`
configuration from the build scripts to the nexus-specific core
configuration header file.
Specifically:
- Added `#define OPENTHREAD_CONFIG_MULTIPLE_INSTANCE_ENABLE 1` to
`tests/nexus/openthread-core-nexus-config.h`.
- Removed `-DOT_MULTIPLE_INSTANCE=ON` from `tests/nexus/build.sh`.
- Removed `-DOT_MULTIPLE_INSTANCE=ON` from `tests/fuzz/oss-fuzz-build`.
This change centralizes nexus-specific configurations in the header
file, making the build scripts cleaner and ensuring consistent
configuration across different build environments that use the
nexus core config."
Due to a state retention issue in the unit test platform, TCAT tests were passing in ways they should not.
Now with the new settings/flash clearing per #12875 applied, these tests were failing.
This fixes TCAT unit tests to pass again and better express the expected behavior also.
Issue: state was retained between OT instances in the unit test platform, across tests.
This commit adds settings and flash clearing as part of testInitInstance().
This commit simplifies the Simulation 1.4 workflow by removing the
compiler and architecture matrix. Run-time issues due to compiler
differences or architecture have not been an issue, so testing a single
configuration is sufficient to reduce CI resource usage.
The workflow now uses the default environment instead of explicitly
testing both gcc/clang and m32/m64 architectures.
This commit adds a compile-time check in `time_sync_service.hpp` to
ensure that `OPENTHREAD_CONFIG_RADIO_LINK_TREL_ENABLE` is not
enabled alongside `OPENTHREAD_CONFIG_TIME_SYNC_ENABLE`. The time
synchronization feature is experimental and currently only supports
IEEE 802.15.4 radio links. Attempting to use it over TREL is
unsupported and will now result in a build failure.
