Android ESP Provisioning: Play Store ESP BLE works, but not source code version

[joe_fang_iD]

Hopefully this is the right place to post this. I'm trying to test out ESP-IDF's provisioning features, in the particular, the app. On the ESP32 side, I'm running the ble_prov example in the provisioning folder.

The app I downloaded from the Google Play Store called ESP BLE Provisioning works well: clearly sees the ESP32, and can provision.

On the other hand, the code from the esp-idf-provisioning-android example does build and run in Android Studios, but cannot see any BLE devices.

Any assistance would be greatly appreciated.
