Hi,
Now I’m trying to test the downlink via the MESH topology(one hop).
Chirpstack Version:
chirpstack-concentratord: 4.4.2
chirpstack-gateway-mesh: 4.0.0
chirpstack-mqtt-forwarder: 4.3.1
chirpstack: 4.9.0
[Topology]
Sensor )))) Relay Gateway ------- Border Gateway ----ChirpStack LNS
*Border Gateway in the shielding box
Currently I use the ABP node with the RX Delay=5 to trigger the downlink process.
I always got the “Handle mesh event error: Tx Ack error: TOO_EARLY” error message.

Is there any way to avoid the “TOO_EARLY” status?
Thanks.
