I am trying to re-connect my android phone to nrf51822 using already existing bond, I am able to reconnect to the card, but the issue is I still need to perform gatt.discoverServices, and then setCharacteristicNotification, then writeDescriptor to receive the callback of the bluetooth device.
There is no problem for me to connect and bond to the target device with my android phone, the issue is that once I restart the bluetooth on the phone, and try to reconnect to the bluetooth device, I still need to recreate a new bond in order to communicate with my target device successfully. Is there anyway to use existing bond instead creating a new one? (By recreating a bond I mean enable notification and write descriptor to create bond)
I am expecting that only the first time when I connect and bond the target bluetooth device, i need to enable notification and write descriptor, and then if android's bluetooth got turned off and back on, I should be able to use the existing bond(which I can see from my bluetooth setting, my device name is still there) so I do not need to redo the same service discovery, setCharacteristicNotification, then writeDescriptor again. Is this possible?
