Using lora without syncword #8

Open CajKos opened 2 years ago

I was wondering if it is possible to send and receive without using a syncword, or would this have the same effect as the public syncword? Kind regards!

Syncword is part of LoRa protocol. It is used to isolate different LoRa devices, only LoRa devices with the same syncword can communicate. Syncword can be any value but some of them might not work, so it's best to stick with the default value, public 0x34 (used by LoRaWAN) or private 0x12.

So no, you cannot TX RX without syncword.
