Hi @Chris,
I’m experience another strange serial port issue with the Zigbee-binding:
210 │ Active │ 80 │ 2.3.0 │ ZigBee Binding
211 │ Active │ 80 │ 2.3.0 │ ZigBee CC2531 Binding
When the coordinator is the only USB-serial device plugged into the system, the binding is initializing it.
But when I have a couple of other serial devices connected, it fails permanently.
Well, I’m aware of some of the common issues regarding USB-to-serial devices connected to Linux. So I have symlinked the Zigbee coordinator ( /dev/zigbee, since this had the same issue now to /dev/ttyUSB99 to match a common pattern):
SUBSYSTEM=="tty",ATTRS{idVendor}=="0451",ATTRS{idProduct}=="16a8", SYMLINK+="ttyUSB99", GROUP="dialout", MODE="0666"
/etc/defaults/openhab2 is adjusted as well:
EXTRA_JAVA_OPTS="-Dgnu.io.rxtx.SerialPorts=/dev/ttyUSB99:/dev/bluegiga0:/dev/bluegiga1:/dev/bluegiga2:/dev/bluegiga3:/dev/bluegiga4"
If it’s the only serial device, then it works:
2018-07-09 15:14:41.926 [hingStatusInfoChangedEvent] - 'zigbee:coordinator_cc2531:88c83f29' changed from UNINITIALIZED to INITIALIZING

2018-07-09 15:14:46.804 [hingStatusInfoChangedEvent] - 'zigbee:coordinator_cc2531:88c83f29' changed from UNKNOWN to ONLINE
But if some Bluegiga BLE dongles are connected to the system as well, the binding can’t open the serial port:
2018-07-09 15:00:12.061 [ERROR] [ding.zigbee.handler.ZigBeeSerialPort] - Serial Error: Port /dev/ttyUSB99 does not exist.
2018-07-09 15:00:12.061 [ERROR] [.cc2531.network.ZigBeeNetworkManager] - Failed to open the dongle.
btw: The Bluegiga-dongles are symlinked to /dev/bluegiga0, /dev/bluegiga1 etc.
More than this: When I remove a CC2531 coordinator from the paper UI and add it back again, it only offers a wrong serial port (/dev/bluegiga1) in the drop-down list to me:
Since the field is not editable, I cannot adjust to the /dev/ttyUSB99 in that case.
Any idea what’s wrong here?
As I said, plug in the CC2531 first, start openHAB and then plug the Bluegigas later works. But this is not a solution for daily operation. And I should have mitigated this need by the symlinking stuff …
