This issue is encountered while trying the BLE_Uart example without changing anything.
Based on the current consumption I’m seeing and lack of readable advertisements, it seems that all BLE activity ceases after 30 seconds after boot. I would expect that since the device is configured for BLE UART, after the initial 30 seconds the device would still advertise.
Current consumption t>30s:
@beegee can you confirm this behavior? Tested on staging, RAK4630-R.
