I have the problem with serial port closed unexpectedly again. See this topic
Tried today updating NR to V1.1.2, no problems with that. However also the Serial node is update then to 0.10.3 and that gives me the problems again.
The port will give me Serial port /dev/ttyUSB0 closed unexpectedly in the debug window.
This time downgrading the serial node to 0.8.3 was not possible, couldn't get it working.
The usb serial port is an FTDI convertor connected to my smart meter. One side usb and the other side rj11 connector. This smart meter will dump every second some data at 115K.
If I put in the usb connector to my pi3b+ and the rj11 at the other end of the cable NOT to my smartmeter if works, the serial node has the status connected and no error in the debug window.
But as soon I'm plugging in the rj11 in the smartmeter and the data is coming in the node status is disconnected and the debug window shows the above message.
Resorted a backup and i'm back at NR 1.0.3 with serial node 0.8.3 works fine again.
However I can't stay forever at these versions and want to upgrade asap.
How can we solve or debug this problem?
