Bonding at initialize() or reading Char that requires bond

Hello again!

Thanks for you last fix, it solved my issue. 😃 I’ve ran into another strange case. Let’s say you want to connect to a device and bond that device. What is the flow for this? I’ve tried several different ways but ran into different issues.

• enqueue a bond in the initialization?

/** BleManagerGattCallback **/
        override fun initialize() {
            super.initialize()
            createBond().enqueue()
            readCharacteristic(bondCharacteristics).with(bondDataCallback).enqueue()            
            readCharacteristic(modeCharacteristics).with(modeCallback).enqueue()
            setNotificationCallback(modeCharacteristics).with(modeCallback)

        }
        ...

In the case above everything below createBond() will be ignored.

• read a characteristic that require bonding, and handle onBondingRequired?

        override fun initialize() {
            super.initialize()
            readCharacteristic(bondCharacteristics).with(bondDataCallback).enqueue()           
        }
        ...

In this case I get:

E/BleManager: onCharacteristicRead error 8

It does not seem to match the BluetoothGatt.GATT_INSUFFICIENT_AUTHENTICATION, see https://github.com/NordicSemiconductor/Android-BLE-Library/blob/master/ble/src/main/java/no/nordicsemi/android/ble/BleManager.java#L1316 However, it will log in the nRF Logger: Error (0x8): GATT INSUF AUTHORIZATION.

Or is the right way to go to create a bond after connect done callback and then do additional reading for characteristics that require bond?

Great! We are then almost ready with releasing it as 2.0-final. I’m just busy fixing bugs in DFU, I didn’t look there since long time… Thanks for the help with the library!
