I've got this GSM/GPRS Shield
and can not initialize it.
The most close schematic seems to be an IcomSat GPRS Shield, which use standard libs.
My configuration is Arduino 2560 + that GPRS Shiled + dc power plug 12V 1A.
I've noticed from descriptions of such configurations, that not all digital pins are ok for RX TX to /from this shield, but generally i simply can not catch the way of wirering those digital pins, because on my shield as you can see there are two 3-pins connectors with jumpers (first three marked sw-tx-hw, another three marked sw-rx-hw). While on other such shields there are multi-pin connectors.
For example here is a correct connection of digital pins of arduino 2560 to rx/ tx of IcomSat Shield. But in my case where i should plug those D2 and D13 pins ? What should be position of jumpers or they should be removed ?
And one more issue - with 12V power plug, voltage regulator on arduino is not very happy, the temperature is around 80 deg.. Is it normal ?
And the last question - is there a direct NOKIA display connection on this shield like on EFcom's for example ?
