I've got a Siemens A60 (GSM/GPRS) phone hooked up to an Arduino (mostly using tutorial http://tronixstuff.wordpress.com/2011/01/19/tutorial-arduino-and-gsm-cellular-part-one/
which I know is actually for a shield, but I thought it a good starting point) I used the siemens charger cable and soldered in the Rx, Tx pins I got info on from pinouts.ru
The Arduino is communicating with the phone because I can send AT commands via the terminal program from the tutorial http://sites.google.com/site/terminalbpp/
. When I dial the phone, data gets sent via the Arduino to the terminal. Also I can terminate calls via the terminal.
When I turn on the phone I don't get all the SIND messages shown on the tutorial, which is a concern. When I try AT+SIND=? i get ERROR. When I try to set a GSM band I get and error
When I dial a number on the terminal: ATDphonenumber I get a NO CARRIER message.
setting the default network operator (orange) works fine and I can just dial out using the phone keyboard even when still attached to the Arduino.
I feel as though I'm close to getting it, but I am a beginner in this stuff, and it's time to ask the experts.
Can anyone help?
