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. If for some reason the module cannot find the Access Point, it goes into auto association
mode and gets busy scanning and trying to join a network. This may cause the UART to become
unresponsive for a brief amount of time and you may lose the data sent to the module while the module is in
this “not associated” state making it difficult to get into command mode and configure the module
Version 2.21 of the firmware fixes this issue. The auto-join feature is disabled when in command mode.
This makes it easy to configure the module. Auto-join will re-enable when you exit out of command mode.
The auto join feature can be disabled by setting the
set wlan join 0
. This will prevent the WiFly GSX
module to attempt to associate to a network that does not exist.
Another alternative is to boot the module in adhoc mode by using the PIO9 adhoc/factory reset jumper. If
this is high on power up, the module will not associate to any network; it will use the temporary adhoc
mode. When in adhoc mode, you can configure the network settings.
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.
