For starters, a bit of context We are new to LoRaWAN, with which we are trying to use the TTIG to forward packets from Sensoterra autonomous soil moisture probes up to their servers. We have a fairly simple design with 8 probes positioned in an orchard around a gateway that is powered via a solar panel, and connected to the internet through a 4G dongle. Distance is quite low in comparison with what other people have been trying to do with TTIG, i.e. <100m. We can easily monitor the gateway through TTN v2 console so we know it is up and running, and we have other ways to check if there is a power loss on our setup.
Once we woke the sensors for the first time everyone was happily connected with a fairly good declared network power from the probes. But after a few days everybody progressively stopped emitting even though nothing changed in the setup. That is why are now trying to have a look at the TTN gateway trafic interface, on which we noticed that there were comparatively more and more join/accept requests and less and less uplink and downlink ones.
According to your experience, what could be the cause of this ? Is there any element we could have a look at in the trafic monitor or elsewhere to try understand what may be the issue ? I feel like the documentation is quite hard to reach and fully understand for newcomers, so my reason for being here today.
Thanks in advance !
edit 2 : we moved the antenna a bit further up, and now one probe woke up. Stragely enough, it is one of the farthest probes and declares a very good signal strenght.
