This is what I’ve tried so far:
- Full ChirpStack Gateway OS image V4.1.1 (https://artifacts.chirpstack.io/downloads/chirpstack-gateway-os/raspberrypi/raspberrypi4/3.6.0/chirpstack-gateway-os-full-raspberrypi4-20220802203912.rootfs.wic.gz)
- Full ChirpStack Gateway OS image V4.2.0 (https://artifacts.chirpstack.io/downloads/chirpstack-gateway-os/4.2.0/raspberrypi/bcm27xx/bcm2709/chirpstack-gateway-os-4.2.0-full-bcm27xx-bcm2709-rpi-2-squashfs-factory.img.gz)
In V4.1.1 of the Gateway OS I also tried to explicitly start the chirpstack-udp-forwarder in /etc with the command “/etc/init.d/chirpstack-udp-forwarder start”. Couldn’t see that the UDP forwarder was actually running in /var/log/messages. Inside the chirpstack-udp-forwarder config file it is configured as below. I expected this to allow port UDP/1700 to be opened.
[[udp_forwarder.servers]]
# Server (hostname:port).
server=“localhost:1700”
Similarly in V4.2.0 of the Gateway OS I tried to explicitly start the chirpstack-udp-bridge with the command “/etc/init.d/chirpstack-udp-bridge start” as per this post Gateway OS forwarding to TTN
So to answer your questions, I understood that the chirpstack-gateway-bridge is part of the full Gateway OS image. So unless it isn’t started automatically on boot and I need to manually start it?
Also, I tried opening the UDP/1700 port on V4.2.0 in the ChirpStack config in the web interface and it didn’t work. Can you please indicate how I need to open the port? I did it similar to this post (Enable port forwarding for the OpenWrt - cFos Software). I couldn’t find a post specifically for the Gateway OS web interface.
