Confirmed downlink ACK bits being ignored by TTS

From:

Unable to send downlink to V1.1.0 end device

The repro does not say released against the 1.0.4/1.1.1 - and in fact says there are one active branches (sic) and goes on to list three, so YMMV. The issue here is the body of collective knowledge - if you want to go Chris Columbus and explore new territories, that’s great, but it will leave you figuring some stuff out alone. Plus 1.0.4 requires us to track the DevNonce - there’s lots of little subtle changes - so navigation can need more than no map and just a sextant.

@AnachronisticPenguin

it appears to correctly implement V1.1 if the appropriate compile-time flag is set

Appears being the operative word - LMn is just too complicated to work with the latest version, particularly when the code base has passed through an open source collective - even the ST version which is throughly processed to fit ST’s CubeMX world can result in some oddities - so I end up one version behind on CubeMX which is generally 6 to 9 months behind LMn release. I am looking at ways of reviewing the latest MX vs prior vs latest official release but it is a totally unaffordable time sink.

I’ll still try confirmed downlinks on my v1.0.4 setup if you care to do the same and we can compare notes!
