Hi all 
I put a lot of hours trying to make Concentratord work Waveshare sx1302 Gateway HAT US915 (us915_1)
After fresh install from Openwrt image for raberry pi. In my case Raspberry pi4 B.
Any Idea?
chirpstack-gateway-os-4.2.0-base-bcm27xx-bcm2709-rpi-2-squashfs-factory.img.gz
I start concentratord manually, but it refuses to start at all… here are the infos:
