We have an install base of more than 200 TRB255 devices in the field that are all configured to work as a Modbus RTU to MQTT gateway.
We used a custom made application to accomplish this. Uptil now this has been working fine.
But with batch nr 13 a strange thing is happening:
We have to restart the application on the TRB device in order to prevent time out messages from happening on the RS485 connection.
I searched this forum to find a similar issue. I found one but it had a "PM", so I could not see the solution that was presented there.
Again, it looks like it is only happening on devices with batch nr 13.
I have also tried the latest FW version with similar results.
