BluetoothGatt returns empty service list after connection

Question

I am building an app to read data from a ble device. After connecting to a device I call mBluetoothGatt.discoverServices() and in onServicesDiscovered(..) I am reading the list of service by calling getServices().

The problem is sometimes the list is empty.Has anyone faced this issue.The issue is random and not 100% reproducible.

Answer 1

Yes,this is a Common problem.If you get empty services,you can retry discover . If you get empty more than 3 or 5 times,you should restart you Bluetooth,because it is may be unstable
