OpenThread Daemon (OT Daemon) is an OpenThread POSIX build mode that runs OpenThread as a service. It uses a UNIX socket as input and output, to which clients can connect and communicate using the OpenThread CLI as a protocol.
OT Daemon is used in the Radio Co-Processor (RCP) design. It is included with
OpenThread at /src/posix.
Build
To build the OT Daemon binary, run the cmake-build script and use the
OT_DAEMON switch with the POSIX build:
./script/bootstrap./script/cmake-build posix -DOT_DAEMON=ON
Connect
Once built, connect it to an OpenThread node.
Simulated node:
./build/posix/src/posix/ot-daemon 'spinel+hdlc+forkpty://output/simulation/bin/ot-rcp?forkpty-arg=1'Real node located at /dev/ttyACM0:
./build/posix/src/posix/ot-daemon 'spinel+hdlc+uart:///dev/ttyACM0?uart-baudrate=115200'Control
While an instance of OT Daemon is running, use the built-in controller to manage the connected node:
./build/posix/src/posix/ot-ctlThis opens the OpenThread command line, which you can use as normal.
Alternatively, you can issue OpenThread CLI commands directly from the command
line, using the ot-ctl binary:
sudo ot-ctl stateCodelabs
