BLE stop advertising unexpectedly

Alex Cheng

Our application is a smartband based on nRF 51822 with SDK 9.0 S130, and we found that the device will stop advertising unexpectedly (application is still alive). We have used spectrum to check if the RF signal (37/38/39) is transmitted when the device can't be scanned by using the "nRF MCP" tool. And we found that when the case happen, we can't find the signal on the spectrum. Is it possible that the SD stack already corrupted due to memory corruption ? Is there any suggestion to check what could possibly go wrong ?

    The normal behavior should be that if the device is not connected with the phone it should keep advertising. But the problem is that we found it stop advertising unexpectedly. Yes, it advertise a certain time before it stops. The frequency is very low and it's very difficult to reproduce it. I just doubt that if the SD is corrupted due to unknown reason. Any suggestion ?
