• RYLR998-LoRa

  6 15 6.6 Python

  A python program for 2-way texting with the 33cm band [REYAX RYLR998](https://reyax.com/products/rylr998/) LoRa® module, either with a Raspberry Pi 4, five wires and ten female-female GPIO connectors; or with a Linux PC running a CP2102 USB 2.0 to TTL serial converter, four wires and eight female-female GPIO connectors. No threads, only async

Theoretically, the physical layer of every LoRa transceiver should all be the same, up to the spreading factor, coding rate, etc. Still, I've found that REYAX devices are only sometimes compatible. How do we know that any LoRa receiver can receive any bits sent with LoRa? I wish! Have you tried them? I'm stuck having to order compatible devices for my applications. Here is one: https://github.com/flengyel/RYLR998-LoRa I guess I'll have to be content with practical experience IRL and downvoting on Reddit.

  4 585 4.4 C++

  This is the fully-functional GNU Radio software-defined radio (SDR) implementation of a LoRa transceiver with all the necessary receiver components to operate correctly even at very low SNRs. This work has been conducted at the Telecommunication Circuits Laboratory, EPFL.

One of my projects is to get GNU Radio to decode the variations in LoRa implementations around. That's without encryption of the payload. I'm using this code: https://github.com/tapparelj/gr-lora_sdr
