Hi,
I believed I had everything up and working but trying to send downlink data and nothing is received by the device. Can someone look over my configuration and tell my what I’am doing wrong as I’m lost to what to try next.
ChripStack is run with docker and the device connects with OTAA and sends data, below is my testing config let me know if you want other logs or config or what test I can do to figure out whats going on.
