@krag Yes the same Semtech LoRa wireless protocol

@lupyuen that's really useful.... I thought that PHY layer is proprietary

@krag Says here that "All features of the LoRa physical-layer modulation scheme are described in various patents and blog posts"

https://github.com/rpp0/gr-lora

So it's not officially documented. But people have been using unofficial implementations anyway.

@lupyuen thanks a lot....this can help in implementation of localization of lora nodes without semtech license.
