According to the Android team I need to avoid the first 4 data. I need to convert it to NSString of (ASCII) like below

{"mac":"kanok","pass":"kanok","passphrase":"root1234","ssid":"aplsh90","user":"kanok"}

I can convert it using this website

I know I have to use Convert hex to nsstring or Convert Hex to NSSting and stringByReplacingOccurrencesOfString

How Can I convert?
