gr-lora_sdr is a GNU Radio SDR implementation of a LoRa transceiver.
The bodily layer of the LoRa (LoRa PHY) is a proprietary normal owned by Semtech and other people have been attempting to reverse-engineer the LoRa normal for years with initiatives comparable to GR-LoRa, and over the yr varied individuals have taken over the works and new initiatives have include the most recent one being the gr-lora_sdr GNU Radio software-defined radio (SDR) implementation of a LoRa transceiver.
The mission has been carried out in collaboration with the Telecommunication Circuits Laboratory of the EPFL (École Polytechnique Fédérale de Lausanne) in Switzerland, and gr-lora_sdr is offered as a module for GNU Radio 3.10 with each Tx and Rx carried out, so it may be used with {hardware} suitable with GNU Radio that works within the ISM bands for LoRa (e.g. 433 MHz, 868 MHz, 915 MHz).
The code sends and receives LoRa packets between USRP-USRP and USRP-commercial LoRa transceiver (examined with Adafruit Feather 32U4 RFM95 and Dragino LoRa/GPS HAT).
