Adafruit LoRa Radio Bonnet with OLED — RFM95W @ 915MHz — RadioFruit

I brough one a few weeks ago and I cant get it to send data to the things network I have this code

The code doen't work on the things network v3 does anyone know how to fix this

Unfortunately, the Adafruit CircuitPython TinyLora library does not support the TTN v3 stack.
See the note in this guide https://learn.adafruit.com/multi-device-lora-temperature-network/things-network-raspberry-pi-setup

Since this is not an issue with the RFM9X library.
There probably should be an issue opened on the TinyLora library regards this. I'll open one there.
Since this is not an issue with the RFM9x library, I will close this and reference it in the TinyLora issue.
