hi everybody

i connected CC3000 to my PC with WPA2 mode, base on basic wifi application( edited code at  wlan_connect()). I used conectify to creat an Access Point. I set cc3000 in DHCP mode( type 080000000000000000). After connecting, I can ping CC3000 with IP 192.168.72.104 from my PC. type ipconfig/all in cmd, i get IP of Wireless network connection is 192.168.72.1

Then, I try to send UDP

type 03 return DONE

Type 04051234502c0a84801 ( send 12345 to c0a84801( 192.168.72.1)), it return Done

I used this link

to create a GUI for receiving UDP by my PC by C# with visual studio 2010

And, nothing happened in console

Any ideas to receive UDP by PC ?

    Hi Tuan,

    It would seem that 192.168.72.1 is the default gateway rather than the IP address of the PC. When using the ipconfig comand, be sure to note the IP address, as this is the address you will need to use. Also, I would recommend using wireshark to sniff what is being sent to and from the CC3000. 

    Regards,

    Luke.

    Hi Luke, Thanks for your care

    In Cmd, I can see this line: IPv4 Address.................. 192.168.72.1, So ,I believe that is my IP PC in Wireless Network Connection

    And, this is my adapter setting screen with Wireless network connection 3, it show IP is 192.168.72.1, I cannot change this IP.If i try to change it, close windows, it will restore 192.168.72.1

    I will try using wireshark as your recommendation, please check my problem

    wait for your response and thank you so much

    Hi Tuan,

    Sorry, i missed the part where you set up your own AP.

    One issue I can see is that you don't seem to specify the port number when using the '04' command.
    Reading here, the part that is of particular interest is the Send UDP Data section.

    1. Execute the sendto command (04AAX…Y02BCDEFGHIKLMN)
    • BCDE is the hexadecimal presentation of the destination port.

    I hope this helps.

    Luke.
