Problem z systemem Android BLE: Nieobsługiwany transport dla połączenia w tle

Question

Pracuję nad BLE z urządzeniem BLE: najpierw je znajdź, a następnie połącz. Jednak dostaję błąd:

10-03 17:17:45.641 3854-3930/? E/bt-att﹕ Unsupported transport for background connection 
10-03 17:17:45.641 3854-3930/? E/bt-btif﹕ bta_gattc_init_bk_conn failed 

i jestem w stanie połączyć (nota dziwny stan 133 było przed odłączonym (0)):

Co jest nie tak? Jestem pewien, że zacznę łączyć się z głównym wątkiem.

Answer 1

Oto małe doświadczenie, jeśli centrala BLE znajduje się w stanie skanowania, może być konieczne zatrzymanie skanowania przed podłączeniem do urządzenia peryferyjnego. I encoutnered błąd 133 też https://android.googlesource.com/platform/external/bluetooth/bluedroid/+/android-5.1.1_r13/stack/include/gatt_api.h proszę kasy tutaj, GATT_ERROR

rejestrowania działań może przyczynić się do debugowania,

./adb logcat : S BT-att: BT-BTM: * BluetoothLEint: * BtGatt.ContextMap: *
