RE: Enable debug logging over serial

The logging is still not working properly. I had to undef and redefine the log as printk as a temporary (and quite dirty) workaround.

Best regards,

Hi!

I just tried the same thing with the mqtt example and tried to add CONFIG_MQTT_LOG_LEVEL=4 unfortunately without success.

Any updates on that issue?

I tried to add the line to proj.conf but this lead to the following:

warning: MQTT_LOG_LEVEL (defined at subsys\net\Kconfig.template.log_config.net:50) was assigned the
value '4' but got the value '0'. This symbol has no prompt, meaning assignments in configuration
files have no effect on it. It can only be set indirectly, via Kconfig defaults (e.g. in a
Kconfig.defconfig file) or through being 'select'ed or 'imply'd (note: try to avoid Kconfig
'select's except for trivial promptless "helper" symbols without dependencies, as it ignores
dependencies and forces symbols on). You can check symbol information (including dependencies) in
the 'menuconfig' interface (see the Application Development Primer section of the manual), or in the
Kconfig reference at
docs.zephyrproject.org/.../CONFIG_MQTT_LOG_LEVEL.html (which is updated
regularly from the master branch). See the 'Setting configuration values' section of the Board
Porting Guide as well. It covers Kconfig.defconfig files.

So I added something like

config MQTT_LOG_LEVEL
default 4

to the Kconfig, which removed the error but does not have any effect on logging output.

Hi,

It looks like the "master" branch is a bit under-the-weather. I cannot get the logging to work either, and I'll let the NCS developers know about this.

Kind regards,

Håkon
