I’m in the process of setting up a permanent base with a express plus and rtk2go as an experiment. We are currently using a paired telemetry radios for this (Works great). Looking at options for a longer range, since our application is in rural Kansas where cell is spotty, and wifi networks don’t exist. The LoRa radio looks good, but not available. So is it possible to connect to the rover via rtk2go with a cell phone (data) and the final connection via serial bluetooth. We do want to be able to say we are not in Kansas anymore!
It is https://docs.sparkfun.com/SparkFun_RTK_ … port/#wifi - we also have these https://www.sparkfun.com/products/18572 still in-stock, which should work great for your use-case
Works perfectly with BT and sw maps. So I have radio to radio, ntrip server to client working (rtk2go) and ntrip server to sw maps to rover. next is to turn the express base into a permanent station. After that its onto rover mower.
