Hello,
I am new to BLE. I am currently working on a beacon application. I have used the beacon example code from SDK and modified it. I am using SDK-17.1.0 controller is nrf52832 with softdevice 132. My Beacon mode is working fine. Now I am using button interrupt to put my device into config mode. But as soon as I enter into the advertising init function My device gets restarted. When debugged found that it was showing error code 4. I have gone through one of the post but could not able to solve the error. In my beacon mode, I am directly transmitting my raw data over BLE.

kindly suggest what to do for switching into config mode.... I haven't added any services yet but in future will be added.
Thank You
