Raspberry Pi GSM Add-on V2.0 Setup Documentation?

Is there any where that I can get documentation for the Raspberry Pi GSM Add-on V2.0? I'm trying to follow the instructions that I've found on the internet, but they don't seem to work for me.

4 people have this problem

Even a very simple step by step would really help me. Thanks

Hi, I just bought this device and I was looking for the same thing.

1. disable getty on ttyAMA0
check if someone else is using the tty:
# lsof | grep ttyAMA0

disable service

# systemctl stop serial-getty@ttyAMA0.service
# systemctl disable serial-getty@ttyAMA0.service

2. Power on the device:

it took me one hour to find out that there is a power button and I should press it for 3 seconds to power on the device!

3. Power on the device from bash (yeap, no need to press the power button!)

# echo 17 > /sys/class/gpio/export

# echo out > /sys/class/gpio/gpio17/direction
# echo 1 > /sys/class/gpio/gpio17/value

4. use minicom to connect to /dev/ttyAMA0 and send simple at commands like at, ati4, etc

5. check raspberry temperature:

# vcgencmd measure_temp

# cat /etc/debian_version
