made up of two one byte intervals. The first interval is the OFF period and the
second the ON period. Both are in Hex seconds (not decimal). The maximum value
is 20 seconds for either of the periods. Default is 0000 always actively waiting for a
connection.
Example: S|,0120
20=Decimal 32).
Display basic settings. Address, Name, Uart Settings, Security, Pin code, Bonding,
Remote Address.
Display extended settings: service name, service class, device class, configuration
Timer.
Display remote side modem signal status.
Display other settings. Configuration character, I/O port values, debug mode.
Display stored settings for command X. These commands correspond to the SET
commands above.
Example: GS will return 1 or 0 depending on the value of security.
Returns the Bluetooth Address of the device.
Returns the current connection status: 1=connected, 0 = not connected.
Return a hex byte containing the value of the PIO pins
Return the software release version
Temporary UART Change, will change the serial parameters immediately, but not
store them. Command will return “AOK” at current settings, then automatically exit
command mode, and switch to new baud rate.
Baud rrate must be EXACTLY 4 characters = {1200, 2400, 4800, 9600, 19.2K,
38.4K, 57.6K, 115K, 230K, 460K, 921K }.
Parity is E, O, or N (must be capitals)
This command is effective immediately, does not require reboot.
