1. Introduction
This user guide is applicable to the RN-131 and the RN-171 modules and finished products designed by
Roving Networks using these modules. While there are some hardware differences, the same ASCII
command set applies to the RN-131 and the RN-171 modules.
More details on the hardware differences between the RN-131 and the RN-171 module can be found here.
In terms of the firmware, certain specific commands apply to either the RN-131 or the RN-171 module.
set wlan tx <value>
set wlan external <value>
For detailed hardware specifications on the RN-131 and RN-171, please refer to their respective data sheets.
2. Overview
The “WiFly” radio module is a complete standalone embedded wireless LAN access device. The device
has on board TCP/IP stack and applications, requiring only 4 pins (POWER, TX, RX, GND) to design in.
Once initial configuration is set, the radio can automatically access the Wi-Fi network and send/receive
serial data over UART.
