Migration from SDK 12 to SDK 15 problem with NRF_LOG

I am migrating an old SDK app to SDK 15 and I am facing the same issue you solved adding NRF_LOG_DEFAULT_BACKENDS_INIT(); before the calling NRF_LOG

for every source file where I use NRF_LOG I added:

#include "nrf_log.h"
#include "nrf_log_ctrl.h"
#include "nrf_log_default_backends.h" //(I added this new one to each file)

also I am getting the following error:

..\..\..\..\..\..\components\libraries\experimental_log\src\nrf_log_internal.h(315): error: #65: expected a ";" extern nrf_log_module_dynamic_data_t NRF_LOG_MODULE_DATA_DYNAMIC;

Found out what needed to be added in my sdk15, it was the header file:

#include "nrf_log_default_backends.h"

and in the main function just before calling NRF_LOG for the first time

NRF_LOG_DEFAULT_BACKENDS_INIT();

has to be added

I did not change a thing in my sdk_config.h file,so it is the original one from sdk 15.0.0 it is initialized just like in the TWI_Sensor example:

Those are the only few lines used in my application

bme280_twi_measurement_get(&data);
   NRF_LOG_INFO("Temperature: " NRF_LOG_FLOAT_MARKER " degrees Celsius.\r\n",
           NRF_LOG_FLOAT(((float)data.temp)/100));
   NRF_LOG_FLUSH();
}

int main(void)
{
   APP_ERROR_CHECK(NRF_LOG_INIT(NULL));

   NRF_LOG_INFO("BME280 TWI sensor example\r\n");
   NRF_LOG_FLUSH();

Hi,

How did you configure NRF_LOG in your sdk_config.h file, and how do you initialize the NRF_LOG module in your application?

Best regards.
