I use unconfirmed uplinks. 5-10 per hour.
I can’t say for sure if this case was really reduced to SF7, because I didn’t record the console. But I have seen it before, although the receiving values were not so good.
The ADR from the v3-stack is unfortunately bad in my experience and should be adjusted.I measure meteorological data and these should be more or less complete.
Found another case where it is the same.
This is how it looks then, on 03/28 I turned off my TTIG.
Then I waited, but ADR comes to no satisfactory settings. Almost everything is lost

This was not the case with TTN-v2. ADR adapted more slowly, but actually about 50% of the packets arrived after successful adaptation.
Can I use ttn-lw-cli to add my own values?
ttn-lw-cli end-devices set <app-id> <dev-id> --mac-state.desired-parameters.adr-data-rate-index
ttn-lw-cli end-devices set <app-id> <dev-id> --mac-state.desired-parameters.adr-tx-power-index
ttn-lw-cli end-devices set <app-id> <dev-id> --mac-state.desired-parameters.adr-nb-trans
