6.3.38 AT+BTK=<string>{Set Passkey}
This command is used to provide a passkey when PIN? 12345678 indications are received
asynchronously. If a pairing is not in progress then the pin is written to non-volatile memory for future use.
Specifying an empty string deletes the key from the non-volatile memory.
The string length must be in the range 0 to 8, otherwise an error is returned.
Response: <cr,lf>OK<cr,lf>
6.3.39 AT+BTM<bd_addr>{Set Incoming Peer Address}
This command is used to store a peer address for incoming connections in non-volatile memory. A value
of 000000000000 has the special meaning of invalid peer address.
When S register 512 = 3, 4, 6, or 7 it waits for an incoming connection from the peer address specified. If
the peer address is not 000000000000, then it waits for a connection from the specified master, otherwise
it connects to anyone.
Response: <cr,lf>OK<cr,lf>

This command is used to delete the peer address previously stored using AT+BTR<bd_addr>.
Response: <cr,lf>OK<cr,lf>

This command is used to display the peer address stored in non-volatile memory, used to put the module
in pure cable replacement mode.
