- *  - Similarly, if the state machine is in "Disconnecting" state and the remote device
- *    sends CONNECT request, the state machine transitions to "Connecting" state.
- *  - Whenever there is any Gatt Write/read, State machine will moved "ConnectedProcessing" and
- *    all other requests (add, update, remove source) operations will be deferred in
- *    "ConnectedProcessing" state
- *  - Once the gatt transaction is done (or after a specified timeout of no response),
