The Instance::HeapCAlloc() method can not be used in constructors when
EXTERNAL_HEAP is enabled but works well when internal heap is
used. This is because the external heap methods are set by public
otHeapSetCAllocFree API after the OT instance is constructed.
This commit fixes this issue by having Instance::HeapCAlloc() using
otPlatCAlloc when EXTERNAL_HEAP is enabled. It also fixes build issues
when MULTIPLE_INSTANCE and EXTERNAL_HEAP are used together.
This is the initial implementation of Thread Border Router
prefix/route management with:
- Create & publish off-mesh routable (OMR) prefix for Thread network
- configure the BR as default route.
- converge to the smallest OMR prefix if multiple prefixes are
present at the same time.
- Create & advertise on-link prefix for infrastructure network
- monitor RA messages on infra link and stops myself if there is
someone else advertising an on-link prefix.
It currently supports single infrastructure link with possibly
multiple BRs. Support for multiple infrastructure links is left for
future.
This commit implements Enhanced-ACK Probing (on simulation platform).
- Add a new public API otLinkMetricsConfigEnhAckProbing which sends
Link Metrics Management Request to configure the probing. This is
called on Probing Initiator side.
- Add a new radio platform API otPlatRadioConfigureEnhAckProbing. This
API should be called on Probing Subject side when handling the
requests from Initiators. This API notifies the radio to start/stop
aggregating link metrics info and include the data into Vendor IE in
enhanced-ACK for the specific neighbor. As discussed in #5746, the
code for doing such thing should be put in radio driver.
- Add a util module util/link_metrics, which provides a group of APIs
to implement Probing Subject side logic for Enh-ACK Probing. Any
platform could use this module to implement the feature easily in
radio driver.
- Add new util APIs in util/mac_frame to generate Enh-ACK Probing IE
(Vendor IE with Thread OUI and SubType = 0) and set value for this
IE.
- Update the implementation in simulation/radio.c to support Probing
Subject side logic for Enh-ACK Probing, using APIs in
util/link_metrics and util/mac_frame.
- Add a test
v1_2_LowPower_7_1_01_SingleProbeLinkMetricsWithEnhancedAcks.py for
testing.
Misc:
- Add check for all the public Link Metrics APIs (Initiator side) to
ensure that the Subject is a neighbor of the Initiator. If the
address is not link-local or the neighbor is not found, an error
UNKNOWN_NEIGHBOR would be returned.
- Update PrepareEmptyFrame so that when it's called for reference
device, its frame version would be set to 2015.
This commit implements TREL protocol to encapsulate and exchange IEEE
802.15.4 frames over a packet switched network (e.g., a wireless LAN).
This commit also provides a TREL IPv6/UDP interface implementation
(using link-local IPv6 unicast/multicast addresses to communicate over
a subnet). It defines a platform abstraction (`otPlatTrelUdp6*`) for
TREL over IPv6/UDP.
This commit also provides an implementation of the TREL platform under
`examples/posix` focusing on simulating the behavior of the link.
This commit implements the CSL feature in Thread 1.2.
- Add macro definitions for low power to control the compiling of
source code.
- Add data and methods for running CSL in Mac and SubMac. This mainly
includes setting CSL parameters, starting/stopping CSL, and the
timer handling process.
- Add otPlatTimeGetAPI and implementation.
- Add CSL transmission implementation. CSL transmission is a new kind
of transmission, the related definition and implementaion for the
whole transmitting process is added.
- Add calling of start/stop CSL in certain cases.
- Implement CSL synchronization maintainence. If a CSL cordinator
didn't get a frame containing CSL IE for CSLTimeout, the CSL
receiver is regarded as de-synchronized.
- Add Cli interface for using CSL.
- Implement enhanced Ack with IE. The original code can only generate
auto ack for Imm-Ack. As CSL requires CSL IE included in enhanced
ack. This PR implements it.
- Add basic functional test for CSL transmission. More tests
corresponding to test plan would be added later.
Currently, the Setting file won't be closed after ot-ncp is reset.
Once ot-ncp receives a RESET command from wpantund, it will reopen
the Setting file and create a new file Id.
This commit closes the Setting file when ot-ncp is reset.
Thread (and OpenThread) does not employ any form of transmit power control.
As a result, while OpenThread provides APIs to control transmit power, it
simply buffers and passes the transmit power value straight through to the
radio.
Currently, the transmit power APIs allow specifying an int8_t in units of
dBm. This is overly constraining for platforms that have more advanced ways
of configuring the transmit power.
This commit removes the transmit power configuration from the core. This
provides better flexibility in platform-specific ways to configure transmit
power.
This commit makes the following changes: It defines the public
`otInstance` as an empty opaque structure which is used by all public
C OpenThread APIs. It defines a new class `ot::Instance` (inheriting
from `otInstance) which is then used in core source files. The
functionality related to the instance is also moved/added into the
newly added `Instance` class (as class/static or member methods).
This commit changes the `InstanceLocator` class to keep track of a
reference to `otInstance` (instead of a pointer) to make it behave
similar to other `ObjectLocator` classes. The method `GetInstance()`
in all locator objects is updated to provide a reference (instead
of a pointer) to `otInstance`.
The logging macros are updated such that a reference to `otInstance`
is passed as the first argument (with the exception of
`otLog<Level>Plat()` macros which are used by platform code in C
domain). The documentation for log macros are also updated.
* [timer] multiple microseconds timer support
* Remove TimerSchedulerLocator, Timer inherit from Ip6Locator instead to get TimerScheduler.
* Add separate UsecTimer and UsecTimerScheduler for multiple microseconds timer support.
* [timer] refine Timer names
* Rename alarm header files to alarm-milli.h and alarm-micro.h
* Rename alarm APIs to start with otPlatAlarmMilli and otPlatAlarmMicro
* Rename Timer classes to TimerMilli/TimerMilliScheduler and TimerMicro/TimerMicroScheduler
* [Timer] Refactor Timer code structure
* Create TimerBase and TimerSchedulerBase class for common functions;
* Use TimerMilli/TimerMicro and TimerMilliScheduler/TimerMicroScheduler for different functions;
* Define AlarmApi, so then TimerMilliScheduler/TimerMicroScheduler could use different AlarmApi.
This commit new configuration option `enable-multiple-instances` and
its corresponding option `OPENTHREAD_ENABLE_MULTIPLE_INSTANCES`. When
enabled OpenThread supports handling of multiple instances. By default
this is disabled.
This commit also adds two optimizations for single instance case to
simplify the code and also help reduce memory/RAM usage:
(1) OpenThread objects/classes typically keep a reference to a higher
level object (e.g., many classes keep track of owning `ThreadNetif`)
to be able to access other objects/methods within OpenThread class
hierarchy. In single instance mode, the reference member variables are
removed and instead global functions are used to access the singleton
objects from one class to the other. To implement this, a group of
`<Object>Locator` classes are defined (e.g., `ThreadNetifLocator`,
etc.) which are then used as base class of other OpenThread classes.
(2) OpenThread objects which provide a callback/handler (e.g.,
`Timer`, `Tasklet`, etc.) have `void *mContext` member variable which
is used to keep track of the owner of the object. In single instance
mode the `mConext` member variables are removed since the owner is
expected to be a singleton and can be uniquely determined from the
callback function.
To implement this, two changes are made: First the handler methods are
modified to provide a reference to the object (e.g., `Timer` handler
will provide a `Timer &aTimer` as a parameter of its handler
callback). Second, a new base class `Context` is introduced which
hides the implementation providing an arbitrary context information. A
new static method `GetOwner(aContext)` is added to classes which own a
callback providing objects. This method help convert a `Context` to
the reference of the owner class object.
* Diag module should continue to send next packet even if the last transmission failed
* Remove unnecessary aFramePending parameter from diag transmit done callback
* Add otPlatRadioGetReceiveSensitivity() API
* Add a new otPlatRadioGetReceiveSensitivity() API to get sensitivity value;
* Use the receive sensitivity value as the noise floor for link metric computation;
* Remove some unused noise floor related functions.
* Add SPINEL_PROP_PHY_RX_SENSITIVITY Spinel/NCP property
* change user mode openthread to enable dynamic memory allocation in mbedtls
* complete merge by adding OPENTHREAD_MULTIPLE_INSTANCE to last file
* remove some extraneous changes that got pulled in accidentally
* fix spacing
* fix crash in existing tests due to this change
* fix x86 build
