This suggests that the Bluetooth functionality in your application is working. Can you provide examples of things that aren’t working? Are those components running in different threads? Do you have any logs from the device?

Thanks for your reply
When I plug in the debugger to check the error, it seems that it does not have the above system hang and works normally. Yes, I can disconnect and reconnect to the phone. And I can reset by sending the reset command from the phone to the device.

Hello,

[quote user=""] I can still connect to the phone via BLE (I think the core application seems to be stuck but the core network is not stuck).[/quote]

Are you also able to disconnect then re-connect again?

If you are able to reproduce this again, I would recommend you attach a debugger to it and see if you can determine where the program hangs. Alternatively, enable debug logging.

I also recommend upgrading to SDK v2.4.4 as this include fixes for Anomaly 165 and Anomaly 168 that may be relevant to your issue.
