Inquiry Scan Window. Sets amount of time device spends enabling inquiry scan
(discoverability). Minimum value is 0x0012, corresponding to about 1% duty cycle.
Inquiry interval is fixed at 0x800, so time spent in inquiry is 0x12/0x100 by default.
Maximum value is 0x800, set to 0x0000 to disable inquiry scan and make device non-
discoverable. Default value is 0x0200.
Page Scan Window. Sets amount of time device spends enabling page scan
Encryption 1 to enable, 0 to disable.
Set Factory Defaults.
(connectability) . Minimum value is 0x0012, corresponding to about 1% duty cycle.
Page Scan interval is fixed at 0x800, so time spent in page scan mode is 0x12/0x800
by default. Maximum value is 0x800, set to 0x0000 to disable page scan and make
device non-connectable. Default value is 0x0200.
Set UART parity.
needed and must be capital.
Example : “SL,E”
Mode (0=slave, 1=master,2=trigger, 3=auto, 4=DTR, 5=ANY)
Example : “SM,1”
Name of the device, 20 characters maximum.
Example: “SN,MyDevice”
Serialized Friendly Name of the device, 15 characters maximum.
This command will automatically append the last 2 bytes of the BT MAC address to
the name. Useful for generating a custom name with unique numbering.
Example: S-,MyDevice
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%
