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.
+-------------------------+ | MLE TMF UDP IP | | MeshForwarder 6LoWPAN | | _ _ _ _ _ _ _ _ _ _ _ _ | spinel +------------------+ | OpenThread Core | <----------------> | OpenThread Radio | +-------------------------+ UART|SPI +------------------+ POSIX Chip
# 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.
