The current Bluetooth connection will be disconnected. It takes about Supervision 
Timeout(S37) to detect an abnormal disconnection such as power off and moving out of 
service range. In multiple connection modes, a specific connection can be specified to be 
disconnected by specifying the connection number or the Bluetooth address 
The response message of ‘DISCONNECT’ may be displayed on disconnection depending 
on the disconnection condition. You can make it not displayed using S10 register.

made automatically without the authentication process. The maximum number kept on the 
list is 7.
