A C# library for LoRaLoRaAlliance connectivity for Semtech SX127X/HopeRF RFMRFM9X equipped shields on Windows 10 IoT Core Raspbery PI devices.
The repo has the source code for the series of blog posts written as I built this library
Rfm9xLoRaDeviceClient Rfm9XLoRaDevice
There are also projects for each of the shields
Dragino
Elecrow
ElectronicTricks
M2M
Uputronics RPIZero
Uputroncis RPIPlus
Adafruit LoRa Radio Bonnet with OLED RFM95 433MHz
Adafruit LoRa Radio Bonnet with OLED RFM95 915MHz
There is also a parallel development project for NetMF which is documented here
My main use case for the Library is a telemetery field gateway uploading data from a number of remote devices.
Shield from Dragino

Shield from ElectronicTricks

Shield from Elecrow

Shield from M2M

RPIZero Shield from Uputronics

RPIPlus Shield from Uputronics

LoRa Radio Bonnet from Adafruit

The code has been stress/soak tested with a number of clients

Most of my testing has been at 915MHz but I have some 433MHz devices on order.
