As i understand it i should get a PSSTK (welcome) message but i don't get anything.
I've tried switching the power input to external supply and plug in a 12v 1.5A source
Here's a picture of the module, the jumpers etc:Large Image of the module
The only thing i haven't done is solder (or just put) a 220µF capacitor on the 5V and GND because i have a external powersupply that generate "enought" power what i thought.
On the picture i can see the power jumper i set for external power supply just to bee sure you know that.
So how did you connect the external power supply? It has to be connected directly on you gsm module, i did that wrong the first day and got also nothing from the module so connect it directly.
Oh, so basically i gotta solder on the external power supply right onto the module?
I just put the external power supply into the external jack on the Ardo card which was logical to me..
