Hello,
The Example code is running, but only printF() statements are printing and to the PC terminal program.
The example calls for softdevice build 122.
I "think" the example code in main.c is setup properly to enable the Logging data to print. Below is the
log_init() and the sdk_config.h settings for the logger.
/**@brief Function for initializing the nrf log module. */
static void log_init(void)
{
ret_code_t err_code = NRF_LOG_INIT(NULL);
APP_ERROR_CHECK(err_code);
NRF_LOG_DEFAULT_BACKENDS_INIT();
}
sdk_config.h
