Auto Boot SIM808 GSM/GPS Shield
link 2017-10-30 17:01:38 3497 Views1 Replies I try to autostart the DFRobot SIM808 shield (with UNO) without having to push the "boot" button manually.
The documentation says it can be done with pin 12. But all my attempts did not work.
I tried the power up/down method from the DFRobot library:
sim808.powerUpDown(PIN_PWR);
Also this did not work:
digitalWrite(12,HIGH);
delay(3000);
digitalWrite(12,LOW);
delay(500);
Do I have to solder / jumper anything?
Thanks for your help.
