Dear Wiznet team,
I’m contacting you since after a long time we finalized our product for music application PEDAL PLAYER (https://www.youtube.com/watch?v=9jTDP4P8Woc&t=2s) with your chip Wizfi220 embedded, I hope you are well and can help me on a couple of issues.
We’re creating the network as follow, AT-commands are:
// “AT”;
// “AT”;
// “AT+WD”;
// “AT+WM=2”;
// “AT+WAUTH=0”;
// “AT+NDHCP=0”;
// “AT+NSET=192.168.55.1,255.255.255.0,192.168.55.1”;
// "AT+WA=PP-SERVER,8, ";
// “AT+DHCPSRVR=1”;
// “AT+NSTCP=5000”;
// “AT+XDUM=0”;
It works and the wirless connection is OK ( the name of the server is PP-SERVER), devices are connected, maximum 3 right?
Now:
1) We would like to introduce the password authentication (WEP,WPA2-PSK,…) and I introduced the at-command like this:
// “AT”;
// “AT”;
// “AT+WD”;
// “AT+WM=2”;
// “AT+WWPA=12345678”;
// “AT+WAUTH=1”;
// “AT+NDHCP=0”;
// “AT+NSET=192.168.55.1,255.255.255.0,192.168.55.1”;
// "AT+WA=PP-SERVER,8, ";
// “AT+DHCPSRVR=1”;
// “AT+NSTCP=5000”;
// “AT+XDUM=0”;
but it doesn’t work…
Where is the mistake?
2) When we use this router in house everything is OK, but when we use it in open space with large audience there is a disconnection of the server and the system cannot work because the network connection disappear automatically.
Attachment a video of the problem (sorry for the italian language messages but I think its clear the problem).
Please note the signal is very strong and I can assure there were no other networks on channel 8 or interferences around the Wizfi220.
May be the fact that if it is an open network all the people are connecting overloading the supported connected devices capacity of your chip?
Thank you for your answer
