The system configuration settings for each firmware version are given in the tables that
follow.
In order to set a configuration variable, enter “at+ab config xxxx = yyyy”, where “xxxx” is the
variable name and “yyyy” is the value to set. A variable name could also be specified as
“varzz”, where zz is the sequence number of the variable.
Note:
All changes require a reset to take effect.

xxxxxxx
Date code software was built.
Var03
BD_ADDR
00043e260e73
Bluetooth device address (Read-only).
Var04

Var08
UartParity
None
Main UART parity.
Var09
UartDataBits
8
Main UART data bits per character.
Var10
UartStopBits
1
Main UART number of stop bits.
Var11
UartTimeout
44
Timeout used to determine the end of a
message in units of bit times: from 8 to 128 are
allowed.
Var12
