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.

Regards,

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 ?
