Configure dronecell (or ant GSM900 module) on boot

[GoogleCodeExporter]

Dronecell integration have been a long-time wanted feature.
I have it working, flew several trips.

All that's needed now, is to make APM send the few commands (plain text lines) 
- while booting, before sending MAVlink.

Even blind configuration works. (no need to act on feedback from GSM device.)

What you need to send: 500ms between lines unless other stated:
AT+IFC=2,2    //hardware mode   - response is "OK"
AT+CIPMODE=1  //Enable transparent mode   , response is "OK"
AT+CSTT="internet"  //set APN  , response is "OK"
AT+CIICR   //open GPRS  - this can take 2 sec response is "OK"
AT+CIPSTART="UDP","GCS.dyndns.org","14550"   response is "CONNECTED"

of course, the DNS + port number, should be configurable using GUI if possible.

Working on this too. Have a group up on diydrones:

Please join the discussion there too!

Thanks for the AT set!

I'm working on testing the dronecell with the above init and writing a module 
for ardupilot that we can test in the community.

BTW: any error (usually may happen to CIPMODE or CSTT command) is easily 
detected by output of "ERROR"

Some early ALPHA code for initializing a DroneCell from the APM.

See here for the patch and discussion: http://bit.ly/HKxWL2

Thanks, currently using plane, but I'll keep an close eye on this, and maybe 
adapt to plane.

The entire footprint in ArduCopter is 8 lines in two files (two lines in 
ArduCopter.pde and 6 in system.pde). It should be trivial to find the same 
location in Arduplane, just before gcs3.init is called. 

If it proves difficult, let me know and I'll have a try.
