Arduino Yun + GSM Shield, HOW TO?

Official Hardware Classic Yún

Greetings everyone, I'm totally new to this stuff. Could you guys tell me how to connect GSM Shield to Yun? I read the guide on Leonardo but I quite don't get it. I need kind of "baby explanation" :blush: like:
pin 8 on gsm shield -> digital pin on arduino yun and so on.

please? :~

Regards

I own a SIM900 chip and I simply hook it up to the usb host port on the Linux side (through usb/serial converter); I can write my AT commands to /dev/ttyUSB0 ...

kind regards,

Jos

The point is that, I don't have USB port cable. I'm trying to wire them using jumper cables only.

Regards.

EDIT: I'm trying following:
Yun GND -> GSM GND
Yun 5V -> GSM 5V

for these steps, as far as I know, it should be powered on, but I don't see any blinking light on GSM shield.

Afterwards, reading this: http://arduino.cc/en/Guide/GSMShieldLeonardoMega I attached jumpber on GSM:
GSM pin 3 -> GSM pin 8 but no luck.

Any ideas?

EDIT2:
I'm using GPRS Shield module v1.4 by seeedstudios. is that a problem?

Your shield has the same SIM900 chip as I have; I can't power it from an Arduino (it takes up to 2.5A at 5V when it is transmitting or receiving); can't you power it externally? b.t.w. a SoftSerial interface should work fine for RX/TX.

kind regards,

Jos

Hi, I can't plug directly to USB cause I don't have the cable :frowning: and with software serial, it seems to having same problem. I'm using pin 7 and 8 as RX/TX but meh, no RX TX signals at all.

Should I buy http://arduino.cc/en/Main/ArduinoGSMShield instead or do it will have same problems?

Regards.
