Hello ChirpStack support team,
I have a question about how to interpret the “txack” flag/signal shown in Events related to downlinks.
When a downlink is sent and I see txack in the Events, does that mean:
-
the end node actually received the downlink (device-level confirmation), or
-
only that the network server sent the downlink (e.g., queued/emitted to the gateway), with no guarantee the end node received it?
If possible, could you also point out which specific event I should look at to distinguish “sent” vs “received/confirmed by the device,” and whether this depends on using a confirmed downlink and/or Class A/C?
