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.
Seems the strong otPlatOtnsStatus is not used, but the weak
otPlatOtnsStatus was used in the original code if built by cmake.
This commit fixes this issue. Now both cmake and make builds
correctly.
This commit adds transmit security support for simulation radio so
that security Enh-ACK could be handled at radio layer. This commit
also fixes issue #5041.
In Thread 1.2, it is possible to receive an IEEE 802.15.4-2015
packet. Per specification, receiver should acknowledge this packet
with an IEEE 802.15.4-2015 ACK(Enh-ACK). This Enh-ACK can include
header IE with it and requires security enabled bit in FCF be set to
true. It is impractical for the host to generate the Enh-ACK and send
to RCP for transmission within AIFS time(192us). So RCP should prepare
the Enh-ACK by itself, which requires it to fill in the frame counter
and do the encryption/authentication.
This commit tries to address the need of filling auxiliary frame
counter in RCP by including the following changes:
- Move frame counter related functions from MAC layer to SubMac layer,
which is mirrored in RCP.
- Set mMacFrameCounter to RCP using newly added spinel properties.
- RCP reports last used frame counter to host in TxDone and RxDone.
- Add a simulation test for reset verification.

following changes,
- Move Key ID mode 1 AES-CCM* related functions from MAC layer to
SubMac layer, which is mirrored in RCP.
- Distribute the MAC key and MAC key ID to RCP in posix app using
newly added spinel properties.
- Make it possible for radio(either in radio driver or hardware) to do
transmission AES-CCM* if the platform supports by adding radio
capability OT_RADIO_CAPS_TRANSMIT_SEC.
- Enable this for RCP mode on simulation platform.
* use an older version for better compatibility
* add version to project
* only use cpack when OpenThread is the top-level project
* exclude posix apps when BUILD_EXECUTABLES is OFF
* exclude all third_party
This commit is to support OTNS by:
- raising the max number of simulating nodes to 999 if OTNS=1
- implementing the status-push mechanism
To build:
$ make -f examples/Makefile-simulation OTNS=1
This commit should have no change of OpenThread behaviors on platforms
except simulation.
- Use cmake to build.
- Use rcp instead of transceiver simplicity.
- Add virtual time options for cmake.
- Enable readline support for posix apps.
- Use ninja instead of make.
This commit adds enhanced frame pending feature of Thread 1.2. This
requires the platform radio driver to correctly set frame pending bit
for Data frames and MAC Data Request frames.
