I have 3 xbee receiver devices connected to Ubuntu on port ttyUSB0, ttyUSB1, ttyUSB2. Out of these 3, device on ttyUSB2 stops working after every 2-3days. When I open xctu, it shows below error:
Could not find device on port /dev/ttyUSB2. Error initializing xbee device parameters. Connection timeout. Could not read device information.
When I type ls /dev or lsusb, I can see all 3 devices connected and all the 3 serial ports but the device on /dev/ttyUSB2 doesnt respond. When I unplug it and plug it back, it starts operating normally. But again after 2-3 days, it stops responding.
Can anyone please suggest what could be the issue.
I had the same problem. Turned out another program (Cura / Creality Slicer, in my case) was intermittendly checking the serial ports for connected devices, which (I assume) interrupted serial communication for XCTU. Closing the other program solved the issue.
