Example : “SS,SerialPort”
ST,<num> - Config Timer, # of seconds ( range= 0 to 255 decimal,, default = 60 decimal) to allow
remote configuration over Bluetooth after power up in Slave Mode. In all Master
modes, the remote config timer is set to 0 (no remote configuration). In Trigger Master
Mode, this Timer is used as an Idle timer to Break the connection after the timer expires
with no characters being received.
Example : “ST,0” disables remote configuration
Example : “ST,255” enables remote configuration forever
SU,<rate> - Baudrate, {1200, 2400, 4800, 9600, 19.2, 38.4, 57.6, 115K, 230K, 460K, 921K }, only
the first 2 characters are needed.
Example : “SU,96” sets the baudrate to 9600 buad.
SW,<hex word> - Enable low power SNIFF mode. Default is 0000=disabled. SNIFF mode allows
extreme low power operation. Device goes into a deep sleep, and wakes up every
every 625us * <hex word> to send/receive chars.
Example: “SW,0050” enables Sniff mode and sets the interval time to 50 hex * .625 = 50 milliseconds.
This will cause the module to enter low power sleep, and wake once every 50 milliseconds
to check for RF activity. See Section 4.1 for more details on Sniff.
SX,<1,0> - Bonding enabled, creates a single stored connection pair with a remote device.
SZ,<num> - Raw Baudrate (decimal) allows entering of non-standard baudrates. Based on the
formula num = Baudrate * 0.004096.
S~,<0,1> - Profile to use. 0=SPP (default), 1 = DUN DCE, 2 = DUN DTE, 3 = MDM.
See Section 4.2 for more details on Profiles.
S$,<char> - Configuration detect character. This allows a change from the default $$$ to some other
character. Factory defaults returns the device to $$$.
GET COMMANDS
D - Display basic settings. Address, Name, Uart Settings, Security, Pin code, Bonding,
Remote Address. This command is an easy way to check the configuration.
E - display extended settings. Service Name, Service Class, Device Class, Config Timer.
M - display remote side modem signal status.
O - display other settings. Config character, IOport values, debug mode.
G<X> - display stored settings . These commands correspond to the SET commands above.
