TinyCLR OS V2 Seeed LoRa-E5 on Github

The source code of my GHI Electronics TinyCLR-0SV2RC1 Seeed LoRa-E5 library is live on GitHub. The initial test harness uses a Fezduinoand a LoRa-E5 Development Kit.

So far the demo application has been running for 24 hours

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,

            }
         }
         catch (Exception ex)
         {
            Debug.WriteLine(ex.Message);
         }
      }

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.
