    WiFly GSX www.rovingnetworks.com WiFlyGSX-um 9/16/2010 Hardware Interface See the specific module data sheets on the Roving Networks website for hardware specifications, and layout information. 2.1. Power There are two options for powering the RN-131G module directly. DC SUPPLY: Apply 3.3 VDC power to VBATT (pin 20), and V3.3IN (pin 21).

  • Page 7: Status Indictors

    ASCII characters can be sent through a terminal emulator connected to the UART or via Telnet. When using the UART communications settings should match the settings used when RN-131g connects, for example: the default is 9600 baudrate, 8 bits, No Parity, 1 stop bit, and hardware flow control disabled.
  • Page 8 WiFly GSX www.rovingnetworks.com WiFlyGSX-um 9/16/2010 NOTE: You can enter command mode locally over the UART interface at any time when not connected, and also when connected if the appropriate settings are enabled. NOTE: When the WiFly GSX module is powered up, it tries to auto associate to the Access Point stored in the config settings.
  • Page 9 WiFly GSX www.rovingnetworks.com WiFlyGSX-um 9/16/2010 The IP address assigned by Auto IP must be on the subnet 169.254.x.y otherwise the WiFly GSX module will not be accessible. NOTE: If your machine has both wireless and wired interface hardware you will need to disable the wired LAN interface hardware before connecting to the adhoc network.

    WiFly GSX www.rovingnetworks.com WiFlyGSX-um 9/16/2010 4. WiFly Command Reference 4.1. Command Syntax Commands begin with a keyword, and have optional additional parameters, generally space delimited. Commands and options are case sensitive. Hex input data can be upper or lower case. String text data, such as SSID is also case sensitive.

  • Page 11: Set Commands

    WiFly GSX www.rovingnetworks.com WiFlyGSX-um 9/16/2010 When the system boots, all configuration data is loaded into RAM variables from the file called “config”. The set commands actually only modify the RAM copy of variables in the system. In general, the IP, WLAN and UART settings need a save and reboot to take effect, since they operate at boot up time.

By default the WiFly module now sends out a UDP broadcast to 255.255.255.255 on port 55555 at a programmable interval.

  • Page 41: Joining Networks And Making Connections

    WiFly GSX www.rovingnetworks.com WiFlyGSX-um 9/16/2010 12. Joining Networks and Making Connections Configuring the module to make connections is a two set process. First you need to associate with a access point (AP) and second you need to open a connection. To configure the module over the WiFi link is a chicken and egg problem.

  • Page 42: Making Connections

    If the access point is security enabled you will need to set the pass phrase prior to issuing the join command. The RN-131G module will attempt to inquire and determine the security protocol of the access point so you do not have to set the authentication mode. To set the pass phrase for WPA use the command set wlan phrase <string>.

  • Page 43: Controlling Connections Using Pio5 And Pio6

    WiFly GSX www.rovingnetworks.com WiFlyGSX-um 9/16/2010 In the following example assume the network SSID and security have been set correctly and autojoin is set to 1. This will also work in adhoc mode(autojoin 4), however there will be delay in connecting to the adhoc network from the remote computer so set the sleep timer large enough to allow the network to get set up and the autoconn establish a TCP connection.

The most common network is infrastructure in which an access point (AP) is the common point linking all Wi-Fi devices. The access point keeps track of who’s on the local network and directs IP packets.
