# Arduino Wifi shield scan

## Question

Asked by InsaneNeal on 2014-03-11 in Wireless.

Hi, everyone
I am using arduino wizfi shield, whose version is 1.01( I think I could not update it? Do you offer latest version on arduino?).
Now the problem is when I tried to use your myWizFi.wifiScan() function, the results were:

Lots of unknown characters were shown. Where did this guy(õ) come from? And the results also contained some duplicated data. How can I fix it??

Thanks

Hello

I’m not good at Arduino WiFi shield.
But, it seems that the below is related SPI-communication between Arduino and WizFi210.

And, regarding , you had better use the below link.
