i have been trying to fix a little quirk for a week, so we have 5 Dragino temp/ humidity sensors all logged onto a LG16 and to our Chirpstack Server, and they stay online ok, so link seems good, but we have 5x LGT-92 pendant GPS and they logon and show up online when i turn them on, but as soon as it hits its the uplink interval time of 5 mins 300 seconds, it stops. and shows offline in the dashboard for active devices, so far i have checks settings over and over it looks good, i’m a bit lost at why this is happening.
Perhaps everything is working ok. I explain myself.
Chirpstack, in order to show active or inactive device compares the last time it received an Uplink from a sensor with the time setup in the device profile, so if this setup 5 minutes and the end node makes an Uplink every 30 minutes, it will be shown as inactive after the first 5 minutes.
By other hand LGT-92 has a movement sensor, so when it is moving it sends uplinks more often that when it detects that it is stopped, to save energy, so perhaps after 5 minutes from turning it on, it goes on standby mode, it sends uplink less frequently and Chirpstack shows them as inactive.
It ended up the problem was a timer issue, it was different to the user guide, as firmware was different, changed the timer in ChirpStack and all working.
