Would anyone be aware of the location for any documentation on configuring the 4G LTE Hat to operate over the GPIO connection to the PI?
I’ve tried a few things over the last few days but feel like I am missing something simple in the process that is resulting in problems with getting this set up. While the connection via USB has been enough to confirm the viability of the hat in the scenario we wish to use it, we are hoping that shifting over to a GPIO will allow us to use a housing with a smaller form factor for the overall build for our device.
