Hi
We use a kerlink gateway on TTN network.
When the backhaul is ethernet the downlink works fine but when the backhaul is 3G the downlink doesn t work.
I did measure the latency they are lower that 30ms on ethernet and lower that 120ms on 3G.
According to me 120 ms should be ok to handle the 1s (Rx1) or 2s (Rx2) window. Do you have an idea of where the problem come from?
As an additional question that could help:
What is the RX2 policy on TTN? It used to be SF9 does it move to SF12?
Thanks
