The source code of my nanoFramework C# Seeed LoRa-E5 library is live on GitHub. My initial test rig was based on an STM32F691DISCOVERY board which has an Arduino Uno R3 format socket for a Grove Base Shield V2.0. I then connected it to my LoRa-E5 Development Kit with a Grove – Universal 4 Pin 20cm Unbuckled Cable(TX/RX reversed)
So far the demo application has been running for a couple of weeks
The thread '<No Name>' (0x2) has exited with code 0 (0x0).

I have tested the Over The Air Activation(OTAA) code and will work on testing the other functionality over the coming week,

The Region, ADR and OtaaInitialise methods only need to be called when the device is first powered up and after a reset.
The library works but should be treated as late beta.
