 Fixed an issue in which the show rssi command was not working in infrastructure mode when auto join to a wireless network is
disabled (set wlan join 0).
 Fixed an issue in soft AP mode wherein the scan command would not work the first time.
 Added stability to the FTP client mode.
As of version 4.0 03/27/13
 Added support for Multiple Image Format (.mif) files to download multiple images. This new file format contains the firmware
image, applications such as WPS, EAP, web server, and supporting page files.
 The firmware image supports unpacking the files contained in the .mif package.
 Added a secondary UDP broadcast packet to send the UDP discovery message to a secondary server. The size of the secondary
packet is 120 bytes (110 bytes of primary broadcast + 6 byte module’s MAC address + 4 byte module’s IP address).
 Added a new link monitor variable for soft AP mode. It is configurable via the set wlan fmon <seconds> command.
 Added a new configuration web server application onto the module for provisioning/configuring the module to join an
infrastructure network.
 Added a new command to launch soft AP mode network: apmode <bssid> <channel>.
 Added a new command to launch different applications when GPIO9 is driven high, set system launch_string <string>.
 Examples:
- set sys launch_string web_app - launches web server (default)
- set sys launch_string wps_app - launches WPS app
- set sys launch_string eap_app - launches EAP app
 Added the command run <string> to launch individual applications.
 Example:
- run wps
 Deprecated the wps command.
 Fixed a bug wherein the UART would occasionally lock up upon performing the factory RESET command while telnet session was
in progress.
 Fixed a bug in soft AP mode wherein the module would close the TCP connection upon another client being deauthorized.
 Fixed an issue with the link monitor in AP mode to correctly age out stale clients.
 Fixed an issue that would cause the module to crash due to a high-speed optimization error.
As of version 2.36/2.45 09/14/2012
 Firmware versions 2.36 and 2.45 are being shipped together. Version 2.36 supports ad hoc mode, while version 2.45 supports
soft AP mode. All modules shipped with these firmware versions will run version 2.36 by default to maintain backward
compatibility with previous firmware versions.
o You can change the firmware image using the boot image <value> command. After you change the boot image,
you MUST reset the module back to the factory defaults using the factory RESET and reboot commands. Please
note that initiating a factory RESET will result in “breaking” the embedded genuine WiSnap license and may
cause compatibility issues with other SerialIO products.
 Wifly_EZX-236.img—Ad hoc mode firmware for RN-171
 Wifly_GSX-236.img—Ad hoc mode firmware for RN-131
 Wifly_EZX-245.img—Soft AP mode for RN-171
 Wifly_GSX-245.img—Soft AP mode for RN-131
 In firmware version 2.36 (ad hoc version), the auto join feature is enabled to maintain backwards compatibility. In version 2.45,
auto join is disabled and you must explicitly enable auto join mode using the set wlan join 1 command.
 The firmware now supports parity with the set uart flow command.
 Added the i flag to the set wlan channel command, which changes the channel immediately. You can use this feature to go into
AP mode without having to reboot or save the settings.
 In AP mode, de-authentication with the link monitor closes the TCP connection, flushes the UART buffer, and tries to clear stuck
RTS flow control.
