Serial Interfacing
AT
Command
Name and Description
Parameter
Range
Default
BD
Baud rate. Set or read serial interface rate (speed for
data transfer between radio modem and host). Values
from 0-8 select preset standard rates. Values at 0x7A and
above select the actual baud rate, providing the host
supports it. The values from 0 to 8 are interpreted as
follows:
0 - 1,200bps
1 - 2,400bps
2 - 4,800bps
3 - 9,600bps
4 - 19,200bps
5 - 38,400bps
6 - 57,600bps
7 - 111,111bps
0 to 7, and 0x39
to 0xF4240
0x03
(9600bps)
NB
Parity. Set or read parity settings for UART
communications. The values from 0 to 4 are
interpreted as follows:
0 No parity 3 Forced high parity
1 Even parity 4 Forced low parity
2 Odd parity
0 to 4
0 (No
parity)
RO
Packetization Timeout. Set/Read number of character
times of inter-character silence required before
packetization. Set (RO=0) to transmit characters as they
arrive instead of buffering them into one RF packet.
0 - 0xFF
[x character
times]
3
FT
Flow Control Threshhold. Set or read flow control
threshhold. De-assert CTS and/or send XOFF when FT
bytes are in the UART receive buffer. Re-assert CTS when
less than FT - 16 bytes are in the UART receive buffer.
0x11 - 0xEE
0xBE=190d
AP
API mode. Set or read the API mode of the radio. The
following settings are allowed:
0 API mode is off. All UART input and output is raw data
and packets are delineated using the RO parameter.
1 API mode is on. All UART input and output data is
packetized in the API format, without escape sequences.
2 API mode is on with escaped sequences inserted to
allow for control characters (XON, XOFF, escape, and the
0x7e delimiter to be passed as data.)
0, 1, or 2 0
AO
API Output Format. Enables different API output
frames. Options include:
0 Standard Data Frames (0x90 for RF RX)
1 Explicit Addressing Data Frames (0x91 for RF RX)
0, 1 0
