Can we still use the following gateway ( or is it toast )
what else could I do with it ?
Its toast.
Only has a Single SX1276 LoRa device so is not compliant to be used as a TTN Gateway.
Use it for many interesting experiments but don’t connect it to TTS (TTN). As LoRaTracker said, it’s not compliant and may disturb other nodes.
Could I use SX1276 to connect to a new 8 channel gateway as it has discrete inputs that could be used
The manual mentions using a Arduino LoRa library, so presumably you can run independant programs on the ATmega328P processor and use it as a TTN node.
But, it would be best to ask Jaycar for clarification …
