RE: Use different logging modules with different log levels

Hi,

You can register multiple log modules, with their own log level.

You can see how this can be done in the asset_tracker_v2 application.

E.g in main.c you have

#include <zephyr/logging/log.h>
#include <zephyr/logging/log_ctrl.h>

LOG_MODULE_REGISTER(MODULE, CONFIG_APPLICATION_MODULE_LOG_LEVEL);

while in watchdog/watchdog_app.c you have

#include <zephyr/logging/log.h>
LOG_MODULE_REGISTER(watchdog, CONFIG_WATCHDOG_LOG_LEVEL);

CONFIG_APPLICATION_MODULE_LOG_LEVEL and CONFIG_WATCHDOG_LOG_LEVEL is defined by the the project Kconfig and src/watchdog/Kconfig respectively

module = APPLICATION_MODULE
module-str = Application module
source "subsys/logging/Kconfig.template.log_config"

module = WATCHDOG
module-str = Watchdog
source "subsys/logging/Kconfig.template.log_config"

Best regards,

Didrik
