yes, that's what we thought also. Also, the phone is optional for our case (though you need it for sending texts - if you don't have one the display still shows rxed texts and headings/distance to members of the channel)

In my case, only the Heltec boards were easily available, and they lack the GPS that's in the TTgo boards. So I hope there's a way for the phone's GPS to participate!

(Or, since the esp32 has bluetooth, recognize a bluetooth GPS puck? That's extra work and they're quite rare, so maybe nah.)

Otherwise I'm totally fine soldering another GPS onto some random GPIO pins, I have a whole bag of those. I'm just not sure what it would take to get it recognized.

also, adding support to dynamically probe for a GPS attached to GPIOs would be very straightforward (almost identical to the tbeam case). If you're interested in this ping us on the devchat and someone will help talk you through it.

yes. If your radio doesn't have GPS the phone will provide GPS updates to the radio. Everything is treated identially (though there will be a bit higher battery consumption on both the phone and the radio)
