Controller getting Reset after few minutes.

Question

Hi Everyone 
 I have been trying to use nrf52840 on a custom PCB . So far everything is working perfectly except only one single issue which is the controller gets reset and starts execution again from main function . 
 I am using freeRTOS with E-paper(SPI) external memory(QSPI) , few I2C/TWI sensors and Softdevice for BLE (S140) with SDK 15.0 on Segger EMbedded Studio IDE 
 What could be the reason for such abnormal behaviour? 
 Thanks!

Could it be that you have a advertising timeout of 180 seconds (3 minutes), and that the application goes to system_off mode? Please check for places in your code putting the device in system off mode, or calls to reset functions. The application/chip will normally not reset on its own.

The issue is resolved now by changing the timeout parameter to zero but also i had to change the adv flag from BLE_GAP_ADV_FLAGS_LE_ONLY_LIMITED_DISC_MODE to BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE. 
 Thanks!
