33.3.10 +iBDRF — Define A Fixed Baud Rate on Host Connection
Syntax: AT+iBDRF=
Parameters: n=3..9|‗a‘|‗h‘
Command Options:
Sets the baud rate on host serial connection. This
parameter is saved to nonvolatile memory and activated
only after power-up.
n=a set baud rate to Auto Baud
n=3 set baud rate to 2400
n=4 set baud rate to 4800
n=5 set baud rate to 9600
n=6 set baud rate to 19200
n=7 set baud rate to 38400
n=8 set baud rate to 57600
n=9 set baud rate to 115200
n=h set baud rate to 230400
When BDRF is set to a, iChip boots in auto baud rate
mode. In this mode, iChip synchronizes on the first a or
A character sent (normally as part of an AT or AT+i
command) and detect its baud rate. The detected baud
rate remains in effect until the iChip is power-cycled or
issued the AT+iBDRA command.
Default: ‗a‘ (Auto Baud)
Result Code:
I/OK If n is within limits. iChip will continue operating in the
current baud rate setting. Further power-ups will
initialize the baud rate to the new selected value, until a
different AT+iBDRF command is issued.
I/ERROR Otherwise
AT+iBDRF? Returns the code for the specified fixed baud rate
followed by I/OK.
AT+iBDRF=? Returns the message ―3-9, ‗a‘ or ‗h‘‖ followed by I/OK.
