MQTT sample for nRF9161_ns compilation error

JOEBRE

Hello, I.m using SDK 2.6.1 with VSCode.

I created a new application based on the sample /nrf/samples/net/mqtt configured for nRF9161_ns which is listed as a compatible board.

When I build the application I get 2 compilation errors:

C:/ncs/MyApp/mqtt_clean/src/modules/network/network.c:16:30: error: 'CONFIG_MQTT_SAMPLE_NETWORK_LOG_LEVEL' undeclared here (not in a function); did you mean 'CONFIG_MQTT_SAMPLE_ERROR_LOG_LEVEL'?

C:/ncs/MyApp/mqtt_clean/src/modules/network/network.c:110:17: error: 'CONFIG_MQTT_SAMPLE_NETWORK_THREAD_STACK_SIZE' undeclared here (not in a function); did you mean 'CONFIG_MQTT_SAMPLE_SAMPLER_THREAD_STACK_SIZE'?

Substituting,  as the compiler is suggesting, CONFIG_MQTT_SAMPLE_NETWORK_LOG_LEVEL with CONFIG_MQTT_SAMPLE_ERROR_LOG_LEVEL and CONFIG_MQTT_SAMPLE_NETWORK_THREAD_STACK_SIZE with CONFIG_MQTT_SAMPLE_SAMPLER_THREAD_STACK_SIZE fixes the compilation errors.

Not sure the above correction is correct, since when I start the application I do not see any meaningful trace on the serial port with exception of  "*** Booting nRF Connect SDK v3.5.99-ncs1-1 ***" which isn't the output one would expect considering what reported in https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/net/mqtt/README.html.

Im running the MQTT sample on a nRF9161_DK board with a properly working ONOMONDO  LTE CatM SIM.

Could you confirm that SDK 2.6.1 nrf MQTT sample is generating the above listed error ?

Is the fix succested by the compiler correct (CONFIG_MQTT_SAMPLE_NETWORK_LOG_LEVEL ->CONFIG_MQTT_SAMPLE_ERROR_LOG_LEVEL and CONFIG_MQTT_SAMPLE_NETWORK_THREAD_STACK_SIZE->CONFIG_MQTT_SAMPLE_SAMPLER_THREAD_STACK_SIZE )?

    Hi Joel,

    Michial is not available now, and I will continue to help you.

    I just have two questions:

    1) Do you have problem to build the original sample in C:\NCS\v2.6.1\nrf\samples\net\mqtt ?

    2) How do you "generated a new application starting from nrf MQTT sample"? Do you use "Copy a sample" to copy the original MQTT sample? if not, can you have a try?

    Attached is a log when I build from nRF VS Code extension GUI.

    Hello Charlie...

    1) building the sample directly returns the same errors (VSC -> Browse Samples)

    2) I generated the application from VSC-> Create a new application-> Copy a sample-> nrf/samples/net/mqtt configuring for nrf9161_nc target.

    No code modifications at all...

    Regards, Jel

    insert cod hangs .... is there a limit for the number of lines?

    The log shows maybe something missed in Zephyr repository. I have the following suggestions worth to try:

    1. Run "Update SDK" and "Update toolchain". You can find them in Toolchain Manger->nRF Connect SDK v2.6.1-> pull-down arrow.

    2. Try on another PC.

    3. Try to install at a different network environment. For example, try at home if you have installed at an office before.

    I know you have reinstalled the NCS, please pay attention to the installation log when you try the above suggestions, just in case something wrong happens.

    Best regards,

    Charlie

    2) + 3) as mentioned before to make a double check I installed everything at home pn a win11 laptop ... but the errors were exactly the same ....  I'm now trying a complete reinstall from scratch on my office PC ... 

    I'll let you know if  this changes something ...

    Regards, Joel
