I keep all the code and projects descriptions I have written for LoRa devices on a dropbox, There is LoRa code for PICAXE, Micromite and Arduino, a number of reports on link testing and completed code for a Lost Model Locator (Arduino) and High Altitude Balloon Tracker (PICAXE and Arduino).  The balloon tracker code covers the setup of the Ublox GPS that is normally used.
