AT$BTEN=<Mode>, <Password>
<Mode>: 0 - SPP Profile (Default)
<Password>: 4 characters password for connection authorization.
Example: Set "1234" for the Bluetooth connection password
AT$BTEN=0,"1234"
After connecting to the AX9, you will need to input the password with the ending characters
<CR><LF> and send the password to the AX9 in order to establish the connection. This password
sending has to be done within 1 minute after a successful pairing. A failure will result in
disconnection and cause the pairing process to repeat again.
