Adding Logging information to beacon example

[Himanshu]

I am studying the beacon example provided in the SDK (The project is found in following directory C:\Nordic_semi\nRF5SDK160098a08e2\examples\ble_peripheral\ble_app_beacon\pca10056\s140\ses on my computer. It is mentioned here to show the relative path). The SDK being nRF5SDK160098a08e2, the IDE being Segger Embedded Studio. I downloaded the softdevice using ‘Programmer’ in the nRF desktop connect app. The nRF connect is downloaded on smartphone (Samsung S7) and I used this app to ascertain the beacon working. I am using nRF 52840 DK.

Out of curiosity, I wanted to add some logging information in the code.

The main loop, i.e. the 'for' loop has a function

idle_state_handle();

I commented it out and instead replaced it with following lines of code

NRF_LOG_INFO("Beacon example executing");

               nrf_delay_ms(500);

               NRF_LOG_FLUSH();

The header file nrf_delay.h was included to support the nrf_delay_ms function.

With the above changes done, the program was build and downloaded into the nRF 52840 DK. I could see the beacon work but the logging information did not work ( I used JLinkRTTViewer.exe to examine the logging information).

On debugging, the program is stuck in app_error_weak.c file at line number 100 that reads NRF_BREAKPOINT_COND;

Can someone help me with this? I hope I have included the necessary information.

Hi,

Logging is enabled in the example by default, but only on the UART backend. To enable RTT backend, you need to set this config in your sdk_config.h file:

//==========================================================
// <e> NRF_LOG_BACKEND_RTT_ENABLED - nrf_log_backend_rtt - Log RTT backend
//==========================================================
#ifndef NRF_LOG_BACKEND_RTT_ENABLED
#define NRF_LOG_BACKEND_RTT_ENABLED 1
#endif

Best regards,
Jørgen
