I have around 50 devices in the field integrating the RAK4630 module, all of which have been working correctly.
Recently, I spent some time testing newer RUI3 versions. I am currently using version 4.1.1, and I have tested all newer available versions from 4.1.1. However, I’ve encountered some issues. With the exact same application firmware, incoming messages are unreliable: some messages are received correctly, while most of them are lost after the upgrade. Situation is reverted when I downgrade to 4.1.1 again.
Has anyone experienced a similar problem? Is there a known cause or a recommended fix?
If you can give us more details, it will be helpful so we can replicate and see possible breaking changes that affects your code.
Are you using LoRaWAN or LoRa P2P? Is the issue present in all modules you test?
If LoRaWAN, when you say most message are lost, does it mean that the uplinks are not received by the gateway (no uplinks sent to LNS). Any error you see on the serial terminal?
Is the packet loss at the same rate on joining or only when already joined (normal uplinks)?
Anything that might be related to transmit power or reception sensitivity?
Any simple code you use that replicates the issue even stripping other parts (sensor readings, display, housekeeping, etc.) aside from LoRaWAN? This basic code will accelerate debugging if there is problem in the rui3 itself.
