2 weeks ago we updated our loraserver to version 2.8.1, we updated because the upgrading to ADR fit us, the one where you set DR Max and loraserver lowers the DR of all devices.
After the update we kind of saw a high packet loss on nodes that where working perfect before.
We updated the server the 6 of May
So I started digging a little with this node and try to check what is wrong.
We configured the MAX DR to 3 but the device still seems to not be working, If I set maxdr to 0 it seems to work fine.
I get messages with SNR -17 -19 and the server still sets DR to 3
What I don’t really understand is hoy this device worked for 6-7 months losing 1-3 packets day, and now it loses around 50 every day.
Could it be that server is wrongly calculating ADR or TX Power for device? Could it be solved if we upgrade server?
This exect behavior can be seen in around 200 nodes.
