UdpProxy not capturing any packets

Hi, I’m trying to capture and parse the packets passing through my gateway using the UdpProxy, however, it is not capturing any packets, no Join-Request, nothing.

I followed the installation instructions provided in the repository and was trying to replicate the video demonstration seen on Matias Sequeira-Youtube.

My environment: Raspberry Pi 3 B + RAK2245 Lora module (I’m running the gateway using the vendors firmware on port 1700)

cat /etc/os-release PRETTY_NAME=“Raspbian GNU/Linux 10 (buster)” NAME=“Raspbian GNU/Linux” VERSION_ID=“10” VERSION=“10 (buster)” VERSION_CODENAME=buster ID=raspbian ID_LIKE=debian

My steps: Followed the installation instructions on Github.

Tried the following: /laf/tools python3 UdpProxy.py --port 1700 --dst-ip 127.0.0.1 --dst-port 1701

*tcpdump shows traffic on wlan0 port 1700 but not on localhost.

Maybe I’m missing something?

Yes I was trying to run LAF from the gateway(Raspberry Pi). Sorry, my bad, I thought it was the way to go. After changing the gateway configuration to send data to my host computer instead of the server(TTN), and cloning the repository again, it is working perfect! Thank you so much! I really appreciate the quick and precise reply. Issue solved, I will close the tread.

I’m still doing some tests with the SDR’s. Using Gnu-Radio and gr-lora it was possible to capture and decode uplink messages and join-requests in 8 channels simultaneously with the HackRF. I was also able to decrypt the messages using a similar technique as you presented in the conferences. There is still so much to test but not much time now. Regarding your project I would be very happy to get involved. Although my background is not in coding & programming, I’m starting to build a lot of knowledge in LoRaWAN and maybe I could contribute somehow.
