    Hi ,

    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?

    Hi,

    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/

    dmesg | grep ttyUSB

    will show you details of the connected USBs.
