Hello,

i want to by this shield but i can not find any library or code for testing this.

If i would by this shield, i want to uplod data to xively or Nimbits, where can i find code.

I am running at time a sim 900 module from seedstudio, but O2 here has no Support for GPRS, so i must use the 3g module.

Thanks

AJ

Which shield would that be? Your link didn't work.

where can i find code.

In the bottom of the left hand desk drawer on the 12th floor. Or, you write it.

I have this ITEAD 3G shield and have had it working for a few months, just within the last few days it has decided to fail to connect to the network. I cant seem to get any connection, the board is still responsive with AT commands, just cant send receive texts, calls or try to set up emails.

Anyone had this / fixed this?
