Serial Interfacing Commands
AT
Command
Name and Description
Node 
Type
1
Parameter Range
Default
AP
API Enable. Enable API Mode.
The AP command is only supported when using API firmware: 21xx (API coordinator), 
23xx (API router), 29xx (API end device).
CRE
1 - 2
1 = API-enabled
2 = API-enabled 
     (w/escaped control
       characters)
1
AO
API Options. Configure options for API. Current options select the type of receive API 
frame to send out the Uart for received RF data packets. 
CRE
0 - Default receive API 
indicators enabled
1 - Explicit Rx data 
indicator API frame 
enabled (0x91)
3 - enable ZDO 
passthrough of ZDO 
requests to the UART 
which are not supported 
by the stack, as well as 
Simple_Desc_req, 
Active_EP_req, and 
Match_Desc_req.
0
BD
Interface Data Rate. Set/Read the serial interface data rate for communication between 
the module serial port and host.
Any value above 0x07 will be interpreted as an actual baud rate. When a value above 
0x07 is sent, the closest interface data rate represented by the number is stored in the 
BD register.
CRE
0 - 7 
(standard baud rates)
   0 = 1200 bps 
   1 = 2400 
   2 = 4800
   3 = 9600 
   4 = 19200 
   5 = 38400 
   6 = 57600 
   7 = 115200 
0x80 - 0xE1000
(non-standard rates up to 
921kbps)
3
NB
Serial Parity. Set/Read the serial parity setting on the module. 
CRE
0 = No parity
1 = Even parity
2 = Odd parity
3 = Mark parity
0
SB
Stop Bits. Set/read the number of stop bits for the UART. (Two stop bits are not 
supported if mark parity is enabled.)
CRE
0 = 1 stop bit
1 = 2 stop bits
0
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 The RO command is only supported when using AT 
firmware: 20xx (AT coordinator), 22xx (AT router), 28xx (AT end device).
CRE
0 - 0xFF
 [x character times]
3
D7
DIO7 Configuration. Select/Read options for the DIO7 line of the RF module.
CRE
0 = Disabled
1 = CTS Flow Control
3 = Digital input
4 = Digital output, low
5 = Digital output, high
6 = RS-485 transmit 
enable (low enable)
7 = RS-485 transmit 
enable (high enable)
1
D6
DIO6 Configuration. Configure options for the DIO6 line of the RF module.
CRE
0 = Disabled
1 = RTS flow control
3 = Digital input
4 = Digital output, low
5 = Digital output, high
