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 )?

Hello Joel,

Are you sure that you are using the MQTT sample from 2.6.1 with the NCS 2.6.1?

I can build it without any issues for nrf9161dk_9161_ns board.

Best regards,

Michal

Hello, to make a double check, yesterday at home I installed "from scratch" Nordic SDK and toolchain 2.6.1 on my Win11 laptop. As before, I generated a new application starting from nrf MQTT sample and i configured the build for nRF9161 NS... the result was exactly the same ... same errors... unless this is an error affecting only Switzerland, there is definitively an issue in the source code... 

Using a Cygwin console:

> grep -Rnw . -e 'CONFIG_MQTT_SAMPLE_NETWORK_LOG_LEVEL'
./src/modules/network/network.c:16:LOG_MODULE_REGISTER(network, CONFIG_MQTT_SAMPLE_NETWORK_LOG_LEVEL);

shows that the CONFIG_MQTT_SAMPLE_NETWORK_LOG_LEVEL macro appears only in network.c and has no definition.

Where is CONFIG_MQTT_SAMPLE_NETWORK_LOG_LEVEL supposed to be defined ?

Thx for any input ...

Regards, Joel

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...
