Thank you for you comments. I always remember 868, don’t know why.

‘other’ network.

I use both networks but I admire the knowledgeable TTN people.

NbTrans, not important for me. I didn’t managed to think a use-case for that. I implemented it because it was simple and part of ADR command. I don’t wanted the LNS to send constant ADR commands if the device ignores the NbTrans variable.

Olivier Seller proposes NbTrans 4 for static devices at latest TTN conference in Amsterdam, although I don’t see a benefit. If you loose data you have the latest data. I don’t see a problem. LoRaWAN is not blockchain

Perhaps ask the TTN community what would be useful / essential and make it compliant to be a good radio citizen - I for one can work around DevStatus & DeviceTimeReq - the RXParam, RXTiming, NewChannel, etc seem to me to be a function of the network that’s being used and so are known

Well, that’s the reason I try to develop SlimLoRa. With TinyLoRa I had constant downlinks so I abandoned it.

DevStatus it’s ok for battery status. Margin I think is reported wrong. I have to evaluate. DeviceTimeReq is optional, not mandatory, but I think i’ts easy to implement. RXParam yes it’s omitted together with NewChannel. I am not happy for that. RXtiming is working.

Yes, I know about the better solutions. To my surprise the price of hope RF quadrupled. For half the price you get LR1110 which also has GPS. But I have some AVR’s hanging around and my brain has difficultly to jump on another platform like STM32WL. But yes, you have right. STM32WL seems better option. It’s my next step.

I remember many people here using 328p in the past, I thought that maybe they want a library to stop having abandonware.

The CFlist, hmmm, for a cut down stack against a know channel plan, why process it as long as we know it matches? Or even stop any such downlinks as being redundant.

Excuse me, I have language barrier here. I don’t start downlinks. ChMask is on ADR MAC command. I didn’t have never received a CFlist command yet.

I think more serious problem is the absence of confirmed uplinks.
