Sorry for my poor english!
My actual question is: I have already bought " License with HEX-USB+CAN Interface" on April 2013 from Ross-Tech and registered user now, but I want to upgrade to mobile version, so I can use with my mobil phone by simple way. Then, can I just by the interface of HEX-NET WIFI to use mobile version?(Just buy interface of HEX-NET WIFI only, no need to pay license fee again)
