(connectability) . Minimum value is 0x0012, corresponding to about 1% duty cycle.

S-,<Name> This command automatically sets the Bluetooth Friendly Name to “Name-EC42”
where “EC42” is the last 4 digits of the Bluetooth address.
SO,<text> Extended Status String, 8 character maximum. Setting this string to from 1 to 8
characters will enable status messages to be sent to the local serial port. Two status
messages are sent, when a Bluetooth connection is established, the string
”<text>CONNECT” will be sent. Upon a Disconnect, the string <text>DISCONNECT
will be sent. This parameter is useful, for example, when connected to a printer, the
printer can examine an escape sequence, if the <text> is set to ESC%, the printer can parse
the ESC%CONNECT and ESC%DISCONNECT messages without interfering with
normal print jobs. In Trigger or Master modes, the first character of this string is used as
the BREAK connection character.
Example : “SO,ESC%”
