nRF9160 DK LOG_LEVEL in prj.conf

[Oleh]

trying to set the LOG_LEVEL in the prj.conf, building, cleaning,rebuilding... takes no effect.

what am I missing?

Hi,

what are you trying to enable? Enabling logs in a module or change logger configuration?

You need to use CONFIG_....=y to set kconfig option. For enabling certain log level in a module usually you need to set something like:

CONFIG_<MODULE>_LOG_LEVEL_DBG=y

Thanks!

I have set:

CONFIG_LOG=y
CONFIG_SERIAL=y
CONFIG_STDOUT_CONSOLE=y
CONFIG_UART_INTERRUPT_DRIVEN=y

CONFIG_LTE_LINK_CONTROL_LOG_LEVEL=4
CONFIG_NET_CONFIG_LOG_LEVEL=4
CONFIG_NET_APP_LOG_LEVEL=4
CONFIG_NET_SOCKETS_LOG_LEVEL=4
CONFIG_NET_MGMT_EVENT_LOG_LEVEL=4
CONFIG_MQTT_SOCKET_LOG_LEVEL=4

but no luck... :((( somehow, I feel to miss a step...

instead of 

CONFIG_LTE_LINK_CONTROL_LOG_LEVEL=4

you need to do:

CONFIG_LTE_LINK_CONTROL_LOG_LEVEL_DBG=y

I know it may be a bit confusing but it's forced by the way logging options are done in kconfig (choice list rather than value provided by the user, see https://github.com/NordicPlayground/fw-nrfconnect-zephyr/blob/master/subsys/logging/Kconfig.template.log_config).
