6.1 General ST Commands

BR baud

Switch UART baud rate. The STBR command

operates identically to ATBRD command, with the
following exceptions:

• Baud rate is specified as a decimal number in

baud

• Returns ‘?’ if the specified baud rate cannot be

generated with 3% or better accuracy

• The ID string returned is the STI string


Examples:

STBR 300 

switch baud rate to 300 bps

STBR 115200 

switch baud rate to 115.2 kbps 

STBR 2000000  switch baud rate to 2 Mbps 

See ELM327 datasheet for more information about

baud rate switching algorithm.

BRT ms

Set UART baud rate switch timeout for ATBRD and

STBR commands. The STBRT command sets the
same timeout as the ATBRT command, except that the
timeout is specified as a decimal value in milliseconds
and the maximum timeout is 65535 ms (65.5 seconds).

S@1 ascii

Set the device description string returned by AT@1

command. Accepts printable ASCII characters (0x20 to
0x7E). Maximum length is 47 characters. Leading and
trailing spaces will be ignored.


6.2 Device ID Commands

STN11xx supports a number of commands which

can be used to identify the device, get its unique serial
number, and print the firmware and hardware versions.

DI

Print device hardware ID string, in this format:

rX.Y

Table below lists device names for the devices

currently in production, as well as devices still in
development:
