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.
Remote configuration using ADHOC mode
Using adhoc mode to configure the device eliminates the need for the module to be associated with a
network access point. In adhoc mode the module creates it own “on demand” network that you can
connect to via your computer like you would to any other network.
To enable adhoc mode via hardware set PIO9 high (3.3V) at power up. On the RN-134 PIO9 is on the J1
jumper block. When the module powers up with PIO9 set high, the WiFly module creates an adhoc
network with the following
SSID: WiFly-GSX-XX where XX is the final two bytes of the devices MAC address
Channel: 1
DHCP: OFF
IP address: 169.254.1.1
Netmask: 255.255.0.0
With the adhoc jumper in place the above settings override the current saved configuration settings.
From your computer, connect to the WiFly-GSX-XX network. This is an open network which does not
require a pass phrase or pass key. Note: currently the WiFly only supports OPEN mode for creating adhoc
networks.
NOTE: It may take a couple of minutes for Auto IP in Windows to assign an IP address and connect to the
network. You can check IP address of your Windows computer by running the ipconfig command in the
command window. If connected, this command will show you the IP address and net mask for your
computer.
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 a wireless and wired interface hardware you will need to disable the wired
LAN interface hardware before connecting to the adhoc network. If the wired LAN is enabled the computer
will assign an IP address that is not on the same subnet as the WiFly module.
Once connected and you have a good IP address, telnet into the WiFly module on port 2000
telnet 169.254.1.1 2000
You should see the response “*HELLO*”
You can now enter command mode and configure the module.
