I have a GSM/GPRS Module. I power up my module via code using these lines
But I want to add a check of execute this code if only module is not powered up. So which pin should I check?
Additionaly I see there two version of this module. How should I know which one is my module?
You can check the status from VDD EXT Pin. When module power up, VDD EXT is high. Check the pin diagram > https://sixfab.com/product/gsmgprs-shield/
