Support multiple instances of the same service
spkersten opened this issue · 2 comments
The BLE spec allows for several instances of a service or characteristic, however the library assumes there is a unique service or characteristic with a given id.
From Core v4.2 section 3.1 on page 530:
A device or higher level specification ... may have multiple service definitions with the same service UUID.
Android seems to support this as evident by the documentation on BluetoothGattService#getInstanceId:
https://developer.android.com/reference/android/bluetooth/BluetoothGattService#getInstanceId()
Hello, thanks for using the library.
As far as I remember you can use all characteristics you want. If there are multiple with the same UUID then you need to explicitly call RxBleConnection.discoverServices(), sift through them and use RxBleConnection.readCharacteristic(BluetoothGattCharacteristic) API — no?
Yes, I missed that.
