Uplink messages are received but Downlink not received by class A device.Please find attach log of chirpstack gateway bridge,chirpstack network server , chirpstack application server.Please suggest what can be the issue.
Which device, running exactly what version of what firmware?
And also, which gateway?
Usually this is a result of either bugs in the node firmware, mis-entered settings, or occasionally being too far away from the gateway or sometimes even too close to it.
