Error fatal in example "experimental ble app cgms"

[telemedcar]

Hi,

I got a error fatal awhile after the app switched to low advertising.

Could you please tell me where I can to look into ?

I got the error code 8198 from sd_power_systemoff when entering sleep mode.

Can you share the code where this happens?

This debug trace was produced from entereing sleep mode. When I ran the SDK without the USB cable this problem was resolved. Did the USB trace from SEGGER RTT hinder the nRF52832 entering sleep mode ?

The returned error code from sd_power_system_off() is NRF_ERROR_SOC_POWER_OFF_SHOULD_NOT_RETURN. sd_power_system_off should not return when running in normal mode. However, when in debug mode (and using RTT), sd_power_system_off will return with that error code, and the error code will be caught by APP_ERROR_CHECK(). It can be useful to read more in this thread.

If using logging over UART, the debugger will not run, and the same problem will not occur.
