RE: Thread COAP parameters change

Lukasz Duda — Tue, 17 Oct 2017 17:20:50 GMT

Hi Wojtek, Thanks for adding more logs.

Could you check your version of GCC (arm-none-eabi-gcc -v) and give me information about linux distribution? I would suggest to use gcc version from here: developer.arm.com/.../downloads (and export bin folder to your PATH).

Are you able to build and run OpenThread cli example (from examples/apps/cli)?

Some of the errors would suggest, that you didn't add libopenthread_platform_utils.a library to the project.

I built this revision of openthread and I've got errors during project build. Here is log from MAKE:

RE: Thread COAP parameters change

Lukasz Duda — Sat, 07 Oct 2017 17:47:46 GMT

Hello Wojtek,

Please give us more logs so we can help you fix the problems with compilation errors.

Also i would advise you to rebuild OpenThread libraries using specific commit (the one used in SDK release) - 6a15261b (git checkout 6a15261b). Of course you can use the newest one, but then there is always a chance that API has been change.

Side note: Remember that independently of what Sleepy End Device sends to its parent, if device fails three times to deliver any packet in a row (MAC retransmissions are not counted), then node will start attachment process from the beginning (trying to find a parent that is online). I don't know if this is the issue you have expirienced, but it is always a good thing to know.

RE: Thread COAP parameters change

Wojtek — Wed, 04 Oct 2017 12:48:55 GMT

There was few linker problems. I made workaruond for my problem using MessageQueue. Messages are enqueued in case of DETACHED state. I think change of Coap parameters was wrong way.

RE: Thread COAP parameters change

Jørgen Holmefjord — Wed, 04 Oct 2017 12:17:57 GMT

Can you post link to the parameters in the source you changed, and describe the compilation errors you faced after this?
