11.2.

 

UDP Auto Pairing 

 
UDP auto pairing feature temporarily stores the Host IP address of the first remote device that send a UDP 
packet into the module. This host IP address is stored in the RAM which will not survive a sleep or power 
cycle. 
 
This feature allows the WiFly module to echo back to any client that sends a UDPpacket. To use this feature, 
the host IP addressesand set the ip flags. 

 

setip host 0.0.0.0 
setip flags 0x80 
 

 
 

11.3.

 

UDP Retry 

 
This feature adds a level of reliability to the UDP protocol without adding the complete overhead of TCP 
protocol. When enabled,the module waits for a response on every UDP packet sent, (any UDP packet 
coming back in). If the response packet is not received by approximately 250 ms, the same UDPpacket is 
sent out. 
 
This continues until either 

• A UDP response is seen, or 
• A new UDP packet is sent from the module and is acknowledged 
 

To enable this feature, use 

set ip flags <value> 

 

11.4.

 

Using the UDP Broadcast function 

 
The WiFly module can be setup to automatically generate UDP broadcast packets.  This is useful for a 
number of reasons:  

-

 

Some Access Points will disconnect devices that sit idle and don’t send any packets after a time.  
Using the UDP broadcast informs the AP that WiFly is alive and wants to stay associated. 
 

-

 

This feature can be used by application programs to auto-discover and auto configure the WiFly 
module.  If an application is listening for the UDP broadcast, a number of useful parameters are 
present in the package that can be used for auto-discovery.   For example, the IP address and port 
number of the WiFly are both part of the packet, and thus the WiFly can be connected to and 
configured remotely with this information. 
 

-

 

The MAC address of the associated AP, channel, and RSSI value are available in this packet, thus 
enabling a simple location and tracking based function.
