  • UDP Packets
    • SSID: wustl-guest-2.0
      • You can use wustl-guest-2.0 for web traffic but all of the other ports are block by the university firewall. However, we have our own wireless network in Bryan 316 for your use.
    • SSID: Bryan316
      • Your ESP8266 module can use the SSID: Bryan316 but you have to send your MAC Address to Ed Richter (ed@ese.wustl.edu) so he can add your device to he access list.
    • UDP Communication
      • Download UDPExample.zip
      • The .zip file includes example code to transmit and receive UDP packets to the ESP8266.
        • UDP2ESP8266.vi is a LabVIEW program that can run on your computer. It transmits a random number to the IP of your ESP8266 on port 9999 and receives packets from the same IP on port 1000.
        • UDPExample.ino is a slightly modified version of a UDP Example on the ESP8266 forum. This program receives a UDP Packet on port 9999 and retransmits it to the same IP on port 1000.
