title: Configure Wifly module to receive UDP packets
body: <p>I have an RN-171 wifly module connected with a micro-controller.</p>
  
  <p>I am using the UDP-protocol to communicate with the module. Also, I am using the firmware's UDP auto-pair feature to set the host ip. As soon as the module receives a UDP packet, it sets the host IP address to the ip from where it received the data. Now, this host ip cannot be changed without entering into the command mode.</p>
  
  <p>I want the module to behave in the following way:
  Every time it receives a UDP packet, it updates the host ip to the ip address from where that signal came from.</p>
  
  <p>Also, I can use the TCP protocol but it only allows a single connection at a time. One more problem that I faced using the TCP protocol was that if I try to initiate a second TCP connection with the module, it not only refuses the second connection but also hangs the first stable connection. Even if the second connection initiation does not hang the module and it just gets refused, I will be ready to work with TCP.</p>
  
  <p>I have been researching a lot on the web regarding this problem but since these modules are not widely used, they have a very limited support.</p>
