NB-IoT usage and specs

  • Hi,
    I am wondering how exactly the NB-IoT module is supposed to be used. It has a "Power button", and it seems to be neccessary to have it pressed for a few seconds/times/depends on the moon to be able to communicate with the module at all (I am using the default UART). Are the usage instructions or more examples somewhere? Also, the schematics indicate that the power line is connected to GPIO2, is this correct? Is there a reliable way to switch on the module via GPIO2 then (I could not get that working)? A specs document of the used "M5311" would be very helpful with this, but it is nowhere to be found (only a manual of the AT commands is available). Last question: I would like to use TinyGSM, is the module compatible with any of the predefined modems or do I have to extend TinyGSM?
    Any help on this is appreciated!
