Features Features
-------- --------
Though the core functionality of LoRa is described in various patents and blog posts (for a good resource, see [this RevSpace page](https://revspace.nl/DecodingLora)), most of the details are missing. The following features are fully supported by gr-lora: Though there is no official reference implementation of LoRa, the protocol is described in various patents and blog posts (for a good resource, see [this RevSpace page](https://revspace.nl/DecodingLora)). The following features are fully supported by gr-lora:
- Synchronizing to LoRa frames transmitted with any spreading factor - Synchronizing to LoRa frames transmitted with any spreading factor
- Deinterleaving - Deinterleaving

Not supported: CRC checks of the payload and header. Not supported yet:
- CRC checks of the payload and header
- Decoding multiple channels simultaneously
- Clock drift correction for very long frames
This feature set is enough for basic, experimental usage with SDRs.

Hardware
--------
Primarily, gr-lora was developed using a USRP and RN2483 LoRa chip. The following LoRa modules and SDRs were also tested and work with gr-lora:
Transmitters: Pycom LoPy, Dragino LoRa Raspberry Pi HAT, Adafruit Feather 32u4, Microchip RN 2483 (custom board)
Receivers: HackRF One, USRP B201, RTL-SDR
