Hi, my question is about the commissioning of the thread protocol. Not so long ago I created an ish on the github of the thread project, but with software errors I was offered to write in the devzone
link to this issue: github.com/.../6222
I am trying to implement Openthread for a device on an Nrf52811 controller. I was warned about the lack of 192 kb of memory and the lack of an accelerator module. Nevertheless, the protocol does not take up much space, even a little is left for its software. And the acceleration can be transferred to the program.
I collected a thread as follows according to the instructions from their github
make -f examples / Makefile-nrf52811 JOINER = 1
Why did I start building from source? this is due to the fact that I do not find the otJoinerStart() function in the api thread, I decided to build and compile from resources. As a result of building and slipping libraries, I get errors when compiling GCC
What I've done
Compiled the libraries of the thread downloaded through the git and slipped them into the directory of the SDK Nordic
./openthread/output/nrf52811/lib (folder openthread from github) -> (to) ./external/openthread/lib/nrf52811/gcc (folder SDK Nordic v.4.0)
