Station.

Problem:
WiFi module will not associate with network.
Fix:
Make sure the Network SSID does not contain a Space such as My Network
(This should be changed to My_Network). Temporarily disable network security,
there are known compatibility issues between WiFly modules and WPA security.
Problem:
Broadcast transmission from controller is not received on
server/computer.
Fix:
Make sure you do not have any type of antivirus software which could
block TCP/UDP sockets (McAfee is known for this).
Windows firewall can also sometimes block these socket connections, you
can open a port number in Windows Firewall under configuration.
Check Settings in module for server connection. Ensure server is listening
on the transmit port used by the controller.
Make sure WiFi module is associated with network, the flashing green
LED on the module indicates valid connection with the network.
If server/computer is on a remote/sub network (separate network from
the module) make sure port forwarding is configured correctly.
Make sure sensor connected to controller is functioning properly using a
continuity tester (volt meter).
