I tried to look in the documentation and in the code itself for the answer to the question I ask in the title: is it possible to choose whether to subscribe to a characteristic by notification or indication?
(I am in charge of the BLE device firmware, so my knowledge of mobile development is limited. I say this to apologize in advance in case the question is dumb, simple or obvious 😅).
The thing is, I don't know if you can choose whether subscribing to a characteristic via the "subscribeToCharacteristic" method makes use of notifications or indications (i.e. if it will acknowledge or not when receiving data).
I have seen this in the PhilipsHue/flutter_reactive_ble/packages/reactive_ble_mobile/android/src/main/kotlin/com/signify/hue/flutterreactiveble/ble/ReactiveBleClient.kt file:
private fun setupNotificationOrIndication(
deviceConnection: EstablishConnectionResult,
characteristicId: UUID,
characteristicInstanceId: Int
): Observable<Observable<ByteArray>> =
when (deviceConnection) {
is EstablishedConnection -> {
if (rxBleClient.getBleDevice(deviceConnection.deviceId).bluetoothDevice.bondState == BOND_BONDING) {
Observable.error(Exception("Bonding is in progress wait for bonding to be finished before executing more operations on the device"))
} else {
deviceConnection.rxConnection.resolveCharacteristic(
characteristicId, characteristicInstanceId
).flatMapObservable { characteristic ->
val mode = if (characteristic.descriptors.isEmpty()) {
NotificationSetupMode.COMPAT
} else {
NotificationSetupMode.DEFAULT
}
if ((characteristic.properties and BluetoothGattCharacteristic.PROPERTY_NOTIFY) > 0) {
deviceConnection.rxConnection.setupNotification(
characteristic,
mode
)
} else {
deviceConnection.rxConnection.setupIndication(characteristic, mode)
}
}
}
}
is EstablishConnectionFailure -> {
Observable.just(Observable.empty())
}
}
In the iOS implementation I haven't even dared to go in to check it out...
I am supposed to assume that if a characteristic has notification permission enabled it is subscribed by notification and only if notification permission is not enabled then it is subscribed by indication? Which would mean that I can't have both permissions enabled. (My Kotlin knowledge is 0...)
Thanks in advance and apologies if the question is dumb...🙇♂️
