The Radio Bridge modules utilize the UART serial port for communicating payload data between 
modules and for configuration of the modules themselves.  

The serial port runs with these default settings. 

Table 5 Port Default Settings 

Name 

Default Setting 

Baud Rate 

9600 

Stop Bits 

Parity 

None 

The baud rate can be changed using the BD AT command as defined in the AT Commands section. 

All values through the serial command interface are coded as ASCII characters. In other words, 
the 

hex value 0x12 would be coded as the ASCII string “12” which allows for convenient control 

through  a  terminal  emulator.  Host  processors  communicating  to  the  module  through  a  UART 
must convert values to ASCII-coded values. 

3.1.

 

Commands to the Module 

Every  comma

nd  to  the  module  starts  with  the  ASCII  characters  “AT”  which  stand  for 

“attention” as shown in 

the following command structure.

These “AT” commands are defined in 

AT Command Reference

 section.

Messages from the Module 

The messages from the device do not have an “AT” prefix b
