Hello there. Every time I send an uplink in my TTN gateway with DR6 - SF7BW250 - I receive a MAC command with payload 0350FF0001 03 is ADR command. Next byte 50 binary: 01010000 means that the MSB...

clv: So DR6 is not welcome in LoRaWAN? Better to use it in special cases? Same goes with FSK? Yes - at least for TTN, yes and yes. AFAIK, the original chipsets couldn’t do DR6 so …

Again, thanks for your response and perspective on this. I do not yet fully grasp the power dynamics of TTI/TTN or the pulse of this open-source community. Having a discussion here feels like the...

Thanks. descartes: AFAIK, the original chipsets couldn’t do DR6 so … The chipsets of concentrators? FSK is five times faster than DR5, so it seems it has some benefits.

colinsurprenant: My point was about your statement on how things should be done: “real programmers decode on their own platform”, which I assumed to be TTN’s perspective on how I should approach...

All I knows is that a major vendor said their device supported DR6 which the worlds largest Defence Contractor purchased from me for a pilot project but it turns out the vendor had got it wrong and it...

stevencellist: So that has nothing to do with DR6 not being welcome, it’s simply a matter of the ADR algorithm. So, to paraphrase, DR6 is all good but the LNS will never enable it. Is that not the...

Thank you so much for your reply! RSSI & SNR I tried sending the signal from home (distance to the nearest gateway is about 200m). I got the following results: First attempt - the device...

stevencellist: I think DR6 is welcome. I think it can’t be welcome without having an option to tell the LNS a device is DR6 compatible. AFAIK there is no such option in the current code base and as a...

Thanks again, Nick. I appreciate the context you’ve shared about TTN, TTI, and the challenges around maintaining the platform, as well as your insight into the practical realities of its operation....

At 200m I’d expect a far higher (or lower, as you brain works) RSSI. Somewhere around -90 which is sort of a guess value, but -114 is definitely in the km range so this isn’t ideal. [Note to self,...

I’m not fighting my bosses on their CO2 sensors, I was thinking about having my own boxes use DR6 to avoid losing packets to the CO2 sensors. But I rest my case
