Helly everybody,
I'm quite new to this topic.
Anyhow, since days and days I'm trying to get this running.
I'm using an Arduino Uno R3 with an IComSat v1.1 GSM/GPRS Shield from IteadStudio using the SIM900 module.
The IComSat v1.1 has set UART and PIN TXD: 2 and PIN TXD: 3.
According to this website: It says, the POWER_ON Pin is D9 and the RESET is D10.
In order to power this up, I have attached the Arduino to a 9V Battery as well as to the USB cable.
For the communication, I'm using a German T-Mobile SIM-Card with the following settings:
APN: internet.t-mobile
User: t-mobile
Pass: tm
PIN: disabled
I've tried a second SIM-Card of the company Fyve (Vodafone) with the following settings:
APN: web.vodafone.de
User:
Pass
PIN: disabled
I try to establish a GPRS connection to my website in order to store GPS information on 9600 baud. I've used the following AT command series:
This is the result with T-Mobile APN and SIM-Card enabled:
And this is the result with Fyve APN and Sim-Card enabled:
Any idea what the problem might be?
Any help is greatly appreciated!
