Hi, I was very motivated trying the V3 stack so I registered my first device / application yesterday. Unfortunately its not working. I used a (new and unused) Dragino waterleak sensor ( LWL01 -- LoRaWAN Water Leak ) and I think I set everything correctly. Keys double checked, Lorawan Version 1.0.3,…

Assuming that the device responds correctly you may be right. However, the device responce to the ADR request is never received by V3. Therefore I state that the downlink was never received by the device.

Yes, I think our devices don’t receive, or process the downlinks.

Sure but the question is if this is caused by the change in timing that is not accepted by de device (dragino ldr01) or by V3 that is not processing MY settings? As my device works fine in V2, although it seems that the firmware is not processing downlink ok, I would expect that settings in V3 woul…

Also got major issues with V3 and Dragino Water-detectors (LWL01). When switching the same device between V2 and V3 it works fine in V2. But in V3 it tends to run up to SF12 , since it does not seem to get the downlink confirmation. Also, the downlink commands on LWL01 work perfect in V2, but aga…

I updated the LPS8 to support V3, so it no longer routes through V2. This was in hope that it would resolve some timing issues. It did not Here something “strange”? I sent a downlink with two bytes : 0x05 0x00 (should turn off uplink confirmation on LWL01) But the MAC payload becomes 0A 40 …

[image] hellebauer: But the MAC payload becomes 0A 40 …that doesn’t seem right? You payload is encoded before transmission, that is why it looks different. Both LWL01 and LDS01 use the same base firmware which seems to have issues with the downlinks. I’m trying to find time in my schedule to…

Right, after spending a few hours on debugging the LoRaWAN library Dragino based their LDS01 and LWL01 sensor code on it seems there is a serious bug in a binary only part of the library. After the join reply is processed the RX1 delay is correctly set to 5 seconds, only to be reset to 1 second by …

Thanks again Jac! So I guess that’s why the LWL01 & LDS01 work with V2 since RX1 delay is 1s. Being curious, what libraries (V4.4, V4.3, asrlib.a ) were you refering to? I thought that LDS01 and LWL01 were closed source code. About the debugging: I guess the RX1 values can be viewed with AT …

The code for Dragino ASR650x sensors is based on code available on github . That is just the base LoRaWAN code for the chipset (akin LMIC for other hardware). The functionality for the devices is Dragino proprietary code. If you would want to create working code for the hardware yourself you’ll need…
