Have been looking to set the neighbor up with a base and wifi NTRIP receivers to get rid of paying for corrections yearly. Pretty good documentation on the base side (rtkbase), but are there any good options for a wifi to serial device to just tether to the iPhones for internet and output to port C on serial?
Not sure how I missed ESPrtk, looks like it would be as simple as buying a ESP32, the firmware and away a guy goes
I combined a RS232 converter board with an ESP32 running a very simple program that listens on bluetooth and passes the data to RS232. RS232 connects up to port C. That’s all there is to it. I’ve got code on github for ESP32, but it’s designed to switch between a radio link and bluetooth automatically, so it’s a bit more complicated than you’d need. But you can have a look: GitHub - torriem/rtcm_switch: An Arduino sketch for ESP32 to automatically switch between radio and bluetooth for RTK corrections
I just use Lefebure NTRIP client on the phone to pass NTRIP from a caster to the bluetooth receiver in the ESP32.

That’s pretty decent, thanks for that. Too bad there’s no app for iPhone most people are running them around here. I saw the xbee firmware for the ardusimple wifi module is online and might work on a cheap esp32 as well
