I currently own the RTK Mosaic X5 as a RTK base. I also have an Emlid RS+(Rover bought at diff times). The Emlid supports LoRa (I would guess this would be proprietary interface so not easily hackable) & serial output. Since I also own a LoRaWan Gateway (Milesight UG65) I was thinking of possibly trying to use an Serial-LoraWan End Node to the LoraWan from the Emlid. The questions with these components. Do you see a more successful path using two LoRa end nodes (such as SparkFun LoRaSerial Kit - 915MHz (Enclosed)) between the Base and Rover directly or some other serial interface device bridge to the LoraWan (on Rover) and then goto Mosaic over ethernet. Also do you anticipate any issues using RS485 (such as something like the RAK2461 WisNode Bridge IO Lite or Sparkfun equivalent (please suggest)) with the RTK mosaic X5 and Rover as a End node to LoraWan approach.
Using the LoRa radios this would be the Mosaic X5 side
If you’re looking for a plug-and-play minimal effort solution, then the LoraSerial Kit would be ideal
If you’re comfortable with wiring/programming then you could tie in a bare module…though we wouldn’t have much advice for how to configure the milesight side of things
Following up on Lora Serial radios. I purchased the LoraSerial and have serial communication between two computers working fine. I also have the radios working between the Mosaic X5 sending Nmea DTM updates @ 57600 fine. I need to send a corrections using RTCM v3 as I plan to use this radio if the default Emlid RS+ LoRa radio can’t join the multicast. I get about half the data maybe less. Some text comes through, but more often then not I get block blotches unreadable. I reduced the RTCMv3 down to MSM4 to stay within packet boundary. Still no luck in getting readable communication. I reviewed I think the config data for trying this maybe I missed something.
