Hi, Reach and RS can do so, i have done it my self. I work with Archicad and Acrhiterra and export surveypoints to an excel sheet, import to mobiltopographer that is connected to reach via bluetooth. I use one reach as base over a known point and the other to survey with the phone displaying coodinates. So its possible.
Reach need more DIY job and lack the LoRa (radio communication)
ReachRS i precisely what you need. It is ready to go.
You will find all ansvaers in my history topics, i share few here
