I'm creating app that communicates with a BLE device which is advertising packets. We're able to connect to and catch most of the packets, but occasionally, after a few uses and open/closes of the app, I begin to get a SCAN_FAILED_APPLICATION_REGISTRATION_FAILED [0x02] error when connecting to the bluetooth provided in the phone.

I've seen this in 2 different devices so far, but the only resolution I've found is to reboot the phone.

Has anyone else seen this issue or had any success with a fix or workaround?

  • Are you properly closing all BluetoothGatt objects when you are done with them? Are you stopping all scans when you don't need to scan anymore? – Emil Aug 29 '17 at 17:17
  • @Emil That's a good suggestion. I did some research and found that there is a limited pool of Gatt objects. I've updated the code grab them using a singleton pattern to reduce the creation/reference holding, and I thing this has solved the issue on my current two devices. Thanks! – Jeremy Freeman Sep 06 '17 at 15:59
