RN-ISP-UM-1.1
USING ROVING NETWORKS FIRMWARE ON THE WIFLY MODULE
You can use the ISP to monitor and configure the WiFly module while it is running a Roving Networks application.
Additionally, you can go into command mode and configure the various parameters using the ASCII command interface.
The RN-ISP can be used to configure Roving Networks firmware from a Linux, Windows, or Mac computer. However,
before you can use the RN-ISP with a Windows or a Mac computer, you must install FTDI chip drivers from the FTDI
website at http://www.ftdichip.com/Drivers/VCP.htm. Refer to “Appendix A: Installing FTDI drivers for Windows” on page 9
for installation instructions.
NOTE: You cannot develop firmware on a Windows or Mac computer. However, you can use Windows, Mac, or Linux
computers to monitor and configure the firmware.
Launch a terminal emulator program and select the user UART COM port. The default COM port settings are 9,600 baud,
8 bits, no parity, and 1 stop bit. Enter the escape sequence $$$ to go into command mode. The module returns CMD
indicating that it is in command mode.
For a complete list of commands, refer to the command reference section in the WiFly Advanced User Manual, which is
available on the Support page of the Roving Networks web site at http://www.rovingnetworks.com/Support_Overview.
