discoverable. Default value is 0x0200.
SJ, <hex word> - - Page Scan Window. Sets amount of time device spends enabling page scan
(connectability) . Minimum value is 0x0012, corresponding to about 1% duty cycle.
Page Scan interval is fixed at 0x1000, so time spent in page scan mode is 0x12/0x1000 by
default. Maximum value is 0x1000, set to 0x0000 to disable page scan and make device
non-connectable. Default value is 0x0200.
SL,<E,O,N> - Parity. Can be any of, Even, Odd, or None. Only the first character is needed
Example : “SL,E” sets the parity to Even.
SM,<3,2,1,0> - Mode (0=slave, 1=master,2=trigger, 3=auto)
Example : “SM,1” sets the mode to Master
SN,<name> - Friendly Name of the device, 16 characters maximum.
Example : “SN,MyDevice”
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%”
SP,<text> - Security Pin Code, 16 character maximum
Example : “SP,secretcode”
SR,<adr> - Remote Address. 12 hex digits, (6 bytes) no spaces or chars between.
Example : “SR,00A053112233”
NOTE: 2 special characters can be used here:
“SR,Z” will erase any stored address.
“SR,I” will write the last address seen by using the Inquiry command.
This can be helpful when you just have 1 other device in range and want to
quickly store and connect to it.
SS,<text> - Service Name (1 to 16 characters ).
