GPS and LoRa Tutorial with M5Stack in Arduino IDE.
Building on the LoRaReceiver and LoRaSender example sketches for the LoRa 868 module on M5Stack Core, I add the AT6558 GPS unit to the LoRaSender and do a mashup of the GPS_AT6558 and LoRaSender example sketches in Arduino IDE and send GPS data to the LoRaReceiver.

Example sketches:
M5Stack / Modules / LoRa433_SX1278 / LoRaReceiver and LoRaSender
As demonstrated, these are simple sketches that just need to be adapted for the scenario.
M5Stack / Basics / Display
This shows how to overcome the issue where data scrolls off the screen on the receiver. Set cursor to specific location and overwrite.
M5Stack / Unit / GPS_AT6558 / FullExample
Complex display with lots of data, more than needed.
"No GPS data check wiring": I posted an issue on the M5Syack GitHub repository and got this response from GitHub site: use ss.begin(GPSBaud, SERIAL_8N1, 22, 21)
I want to concatenate all desired data into a single string for LoRa packet transmission. I had two problems. Defining the string variable as 'char' gave me an error converting 'int' types when concatenating. So I went with the String function to over come this. But I could not easy get the float precision for latitude and longitude that I desired until I found the dtostrf() function.
