Apparently, as my wife will attest, I’m wrong.
The channel setup & other information comes with some ADR & power settings baked in to the specification.
Certainly I see a very large downlink on my desk, it may be that the extra information increases the size of the downlink and it just doesn’t quite make it to the device.
I’ve been working on a somewhat related issue with ADR and ABP, see ADR features recently introduced to TTS March 2022, I can setup a test to see what my enhanced debug log shows me with an OTAA join with ADR on & off.
To provide context for the testing, why turn off ADR on the device?
