New version 6.5 schedule downlink for each uplink

[tanguy-e]

I'm trying to modify my sketch to work with the new version :

#include <RadioLib.h>
#include <Wire.h>
#include <Adafruit_BMP280.h>
#include <CayenneLPP.h>
#include <Preferences.h>

    Serial.println(F("Could not find a valid BMP280 sensor, check wiring or "
                     "try a different address!"));

But there is a scheduled downlink for each uplink (whereas with previous sketch and previous version not).

[StevenCellist]

Looks perfectly fine to me: the LNS is very actively reducing the transmission power of your device using ADR commands. You can see this from the LinkADRReq commands in the logs, or from the dashboard console when you put it in verbose mode.

[tanguy-e]

So if i understand well your answer there is more downlink because the ADR is more efficient than in the previous version. If i wait a few the number of downlink will decrease ?
My concern is that the number of downlinks authorized by TTN is low....
What's the meaning in power of txPower = 4 ?

[StevenCellist]

I don't think the new version is 'more efficient', unless I unknowingly fixed a bug that unknowingly occurred in 6.4, or introduced a bug in 6.5. How the LNS reacts is different for each moment in time and depends on the exact details of whatever happened during uplink transmissions, with surroundings, electrical interference and what not.
The number of downlinks allowed on TTN is the number of downlinks that you as a user generate; either you 'by hand' sending downlinks to the device, or you programming your device to send confirmed uplinks (or a device trying to join very very often). So-called 'network' downlinks which include just ADR requests, do not necessarily fall under this limitation, unless a device is so poorly designed that it makes the SF / SNR / RSSI go all over the place.
TL;DR: you need not be worried about simple ADR downlinks. Your head will not be smashed in at once. So you can keep the device running for a bit longer with an appropriate interval that adheres to the FUP that you are worried about! (Meaning: not once every minute, but at the very least every three!)

The meaning of txPower = 4 can be found in the LinkADRReq explanation in the spec, boiling down to MaxTxPower - 2*txPower. But might be more properly named something like txSteps or so.

Your head will not be smashed in at once

That's not normal policy, but suspending an account that breaches FUP as egregious as this isn't unusual. And very irritating as the example is set to 5 minutes and the starter notes link to the air time calculator - so no excuses what so ever.

At an RSSI of -44 you have your gateway & device far too close for either RF input circuits comfort. And it is the reason you see the downlinks as the power levels are progressively reduced, so in fact this would fall in to your doing, not TTN. Separation of 5 to 10m with a brick wall intervening is the recommendation.

17:09:22 - Joined
17:09:23 - First uplink - set SF to 7, standard power.
17:09:28.869 -> RLB_PRO: PHY: SF = 7, BW = 125.000 kHz, CR = 4/5
17:09:28.869 -> RLB_PRO: PHY: TX = 14 dBm

17:10:28 - Second uplink, reduce power
17:10:34.243 -> RLB_PRO: PHY: TX = 12 dBm

17:11:34 - Third uplink, reduce power
17:11:39.567 -> RLB_PRO: PHY: TX = 8 dBm

At the same time as being given a link to the air time calculator, I see it has been recommended on the TTN forum you familiarise yourself with the spec With the header size & the operation of ADR issues raised, this would be apposite. And please don't make things difficult for us providing support that isn't in line with FUP. Whilst I can read enough European languages if you are going to change the debug, can you at least leave the technical keywords like uplink in place.

Thank you very much for your help but i can't undertand "Whilst I can read enough European languages if you are going to change the debug, can you at least leave the technical keywords like uplink in place.".
I did not change anything in the debug ?

Serial.println(F("[LoRaWAN] En train d'envoyer la trame ... "));

Whilst it contains a frame, it is sending an uplink - it just makes it easy for the volunteers to scan through the logs quickly to answer your questions if the expected keywords are in place.
