Hello all,
I have a new GSM shield.
This is the shield: https://shop.diy-dreams.de/products/sim-900-shield
I am already able to send SMS with it, however I have or lets say there is a drawback which is not handled in the manual.
On the side of the shield there is a button, which has to be pressed after power on, to make the device dial into the net.
For the project however power off could happen, and the shield should dial in automatically.
I am pretty sure there must be a software solution to fix this issue...
Has anyone an idea?
Kr,
Andreas
