This project forked from tapparelj/gr-lora_sdr

This is the fully-functional GNU Radio software-defined radio (SDR) implementation of a LoRa transceiver with all the necessary transceiver components to operate correctly even at very low SNRs. This work is a collaboration of the Telecommunication Circuits Laboratory from EPFL and the Electronic Systems group from the Technical University of Eindhoven.

gr-lora_sdr's Issues

Update n_required_items once work_done signal is recieved

Noiw once a work_done signal is send it must propagate the entire flowgraph with the required number of input and output items, this should lead to a lag in the system.
It is better to update the number of required items to 1 once a work_done signal is recieved

Cmake errors and GNU Radio version issues

I just tried to run the repository from the conda environment provided. GNU Radio 3.9.5 is installed on my machine, but after setting up the conda environment, the GNU Radio version in that environment says 3.8.2, causing errors when I tried to run cmake. I'm guessing this just means that the environment.yml file didn't get updated to 3.9 when the rest of the repository switched?

GNU Radio 3.8 branch compiling issues

I figure most people using this project are using newer GNU Radio versions. However, for those using 3.8, I had to make the following changes to the gnuradio3.8 branch.

lora_sdr_impl.cc is still referred to on line 55 of lib/CMakeLists.txt. I had to remove that, since lora_sdr_impl.cc was removed in a commit and said to be no longer needed.

I also think there's two references to config.h in the frame_sync_impl.cc causing this error

gr-lora_sdr/lib/frame_sync_impl.cc:4:10: fatal error: config.h: No such file or directory
4 | #include "config.h"

Not sure if removing the second reference below endif is recommened, but I did, and it built afterwards. Haven't tested it yet, but figured I'd share while it was fresh on my mind.

Thank you.

No TX or RX against commercial devices and gr-lora from rpp0

Hi,

Thanks for the port to 3.8 version of @tapparelj we can directly try. I shortly tried the project and tested the RX against TX that are working perfectly. Nevertheless, against gr-lora from rpp0 (https://github.com/rpp0/gr-lora) no uplink frame gets detected using the same config (SF, BW, freq), and neither with a Dragino LG308 gateway, and the RX part of the project doesn't see uplink packets coming from sensors I have including a LoRa shield to easily force the config with Arduino SDK. Only if I conjugate downlink, some garbage happens but not the original text.

Does it work on the original 3.7 version? Or maybe I'm missing another thing? The RX and TX I'm using are taken from the app directory, I only adapted the frequency to match the 868 MHz in Europe, used it with one channel like 868.1MHz, CR=4, SF=7, BW=125kHz, and adjusted the TX_gain to see something in my receiver using a waterfall and FFT.

Thanks in advance!
