OpenThread POSIX app

OpenThread supports running its core on POSIX and transmits radio frames through a radio transceiver.

Currently most platforms in examples/platforms support transceiver mode.

The figure below shows the architecture of OpenThread running in transceiver mode.

# build core for POSIX
make -f src/posix/Makefile-posix
# build transceiver, where xxxx is the platform name, such as cc2538, nrf52840 and so on
make -f examples/Makefile-xxxx


NOTE Assuming the build system is 64bit Linux, you can use the normal OpenThread CLI as described in the command line document. You can also perform radio diagnostics using the command diag.

Wpantund Support

NOTE Assuming the build system is 64bit Linux and wpantund is already installed and stopped.

With Simulation

sudo wpantund -s 'system:./output/posix/x86_64-unknown-linux-gnu/bin/ot-ncp ./output/x86_64-unknown-linux-gnu/bin/ot-rcp 1'

With Real Device

# nRF52840
sudo wpantund -s 'system:./output/posix/x86_64-unknown-linux-gnu/bin/ot-ncp /dev/ttyACM0 115200'
# CC2538
sudo wpantund -s 'system:./output/posix/x86_64-unknown-linux-gnu/bin/ot-ncp /dev/ttyUSB0 115200'

Daemon Mode Support

OpenThread Posix Daemon mode uses a unix socket as input and output, so that OpenThread core can run as a service. And a client can communicate with it by connecting to the socket. The protocol is OpenThread CLI.

# build daemon mode core stack for POSIX
make -f src/posix/Makefile-posix DAEMON=1
# Daemon with simulation
./output/posix/x86_64-unknown-linux-gnu/bin/ot-daemon ./output/x86_64-unknown-linux-gnu/bin/ot-rcp 1
# Daemon with real device
./output/posix/x86_64-unknown-linux-gnu/bin/ot-daemon /dev/ttyACM0 115200
# Built-in controller
