Why can't I listen to the remote control's status of successful frequency pairing?

[Details of the question]

Using the remote control's button or menu shortcuts to bring the remote control into pairing will result in KeyPairingStatus not listening for a successful pairing and therefore will not call back the PAIRED status.

[Reason]

This is a firmware issue. If you use the remote control's keys to enter the pair, the firmware does not push the full pair statuses, MSDK does not receive the PAIRED status and therefore does not trigger the corresponding callbacks.

[Solution]

1. using KeyRequestPairing to bring the remote control into pairing frequencies, instead of the remote control's keys；

2. Listen to the connection status of the flight control to determine if the frequency pairing is successful.
