Comments on: Interfacing Arduino with a Telit GM862

All V+ lines are connected to pin 21 of the Telit module. VCC is connected to a 3.8 V power supply (lipo cell).
For the CREG problem, is the network available if you put the SIM into your mobile?

Hi, i am not able to connect my arduino mega to GM82. Could you explaine me the difference between V+ and Vcc because i receive always
checking network …
AT+CREG?
->buf: AT+CREG?
+CREG: 0,2
OK
done

checking network …
AT+CREG?
->buf: AT+CREG?
+CREG: 0,2
OK
done

I don’t understand what the problem is.

Hi, great work.
what are V+ and Vcc in the diagram.
I don`t know to wich power source must connected.
Thanks

Hi Franck,
I think I know what went wrong. Although this looks like a lib, it is not. Well, it could be.
Please place all files in another directory (not in /arduino/hardware/libraries) and it should compile fine.
Maybe, if I find some time, I will make it a real library.
Cheers,
Alex

Hi Alex,
Same that Peter, I ‘m trying the code (I use arduino 0017) I get this: o: In function `GM862::isOn()’:
multiple definition of `GM862::isOn() /tmp/build6991673787891400230.tmp/test_gm862/GM862.cpp.o:/home/me/Desktop/arduino-0017/hardware/libraries/test_gm862/GM862.cpp:12: first defined here

Any idea what went wrong?
I’m using too an Arduino mega and a telit gm862 gps.

Thanks for your help.

Hi , could i use an Arduino duemilanove with this scheme? I have to change serial3 with serial , it is right or i am costrettoforced to use an Arduino mega?thanks Donato

Hi 3dotter,
no, I’m sorry, haven’t tried that yet.

Hi Alex,

Did you already try the same with the newest NewSoftSerial library (instead of 2 hardware serial ports)? Would be very interesting! What changes are necessary in your code when using this?

Best wishes,
3dotter

Hi Peter,
works for me, just re-verified (on OSX).
Maybe accidently mangled one of the include lines?
And yes, it should be possible to use a Duemilanove, but then you have to rewire your setup for every upload.
Cheers,
Alex

Hi,
I wanted to try this code (I use arduino 0017) but I can’t compile it? I get this:

o: In function `GM862::isOn()’:
multiple definition of `GM862::isOn()

Any idea what went wrong? By the way, if I don’t want to use serial “feedback”, can I write the responds to a LCD so I don’t need arduino mega?

Regards,
Peter
