Has there been any joy/advancements in this?
I'm about to do the exact same thing, but I also want my server to send data back to the Arduino
(using GSM shield too).
Currently I am successfully posting data to a Google Spreadsheet but, as mentioned above I, need to process that data and send some of it back to the Ardunio, which Spreadsheets won't (nicely) allow.
I want to know if there are any major snags/impossibilities, such that I can use a different method if need be.
Thanks!
