LTE Hat

Post by k4vl » Fri Sep 25, 2020 8:17 pm

Has anyone tried stacking an LTE hat under an MMDVM? It seems like something interesting to try. Even if you haven't, What are your thoughts?

I looked at it briefly and I couldn't find how exactly it communicates with the RPi over the GPIO, I suspect it uses the serial port, and if that is the case then it is going to conflict with the MMDVM hat. So in that case you are going to need a hat that connects over USB and not the GPIO.
If someones previous actions are any indication of their future actions, then I predict the deletion and removal of access will happen at any moment. 7-11-2020.

Thank you, that is what I was looking for. It sounds good in theory and would make a great mobile device.

A quick look with a search string of "Pi LTE HAT" found this:

However it uses the whole of the GPIO connector and I don't know how you would make use of it without a HAT that gives you the UHF RF access.

In all honesty bridging to a dedicated 4G device via WiFi is probably more sensible if you don't want to use a phone WiFi hotspot.
