LP-CC1312R7: WI-SUN FAN np_coap_node no serial output and not able to join border router

Part Number: LP-CC1312R7
Other Parts Discussed in Thread: WI-SUN

Hi,

I am following the SDKv6.20 SimpleLink Academy TI WI-SUN FAN Fundamentals. np_coap_node has no serial output.

At spinel-cli.py I had to comment out lines 292 to 295 to resolve a error.

 

After starting the wisunstack from spinel-cli the BR green led is on, and RN green led is blinking. RN still no output at Tera Term.

    Hi Markel, 

    If the error was "module readline unavailable", it is expected on a windows PC.  

    The UART output is disabled in the newer version of the SDKs. To include the trace, in the predefined symbols of the project, instead of having "EXCLUDE_TRACE", change it to "xEXCLUDE_TRACE". The SL-Academy will be updated to have this. 

    The joining of the node to the border router in a WiSUN network typically takes a few minutes.

    Regards,

    Sid

    Hi

    The reason I commented out the spinel-cli.py lines 292 to 295 is due to "argument of type 'NoneType' is not iterable". I found the solution to that here below

    https://github.com/clarkperkins/click-shell/issues/7

    I am using now Python 3.9, But originally I was using Python 3.10 and there was another error that is why I downgrade to Python 3.9.

    From the guide is this supposed to run on Windows PC or Linux "python spinel-cli.py -u /dev/ttyACM0", because I have an error with that.

    Anyway, I will try again tomorrow.

    It worked. The serial print out from RN needs improvement.
