2019-08-12 22:44:15.658 [DEBUG] [e.ember.internal.ash.AshFrameHandler] - ASH: ERROR received (code 81).
This is caused by an issue in the dongle - possibly caused by it getting out of sync with the communications with the computer. There is no way to recover from this other than to reset the NCP.
The binding should attempt to restart the connection, and it does try to do this, but it gets an error opening the port -;
2019-08-12 22:44:17.775 [DEBUG] [ding.zigbee.handler.ZigBeeSerialPort] - Connecting to serial port [/dev/ttyUSB0] at 57600 baud, flow control FLOWCONTROL_OUT_XONOFF.

Not really (sorry) - I’m not a Pi user or Linux expert myself. Personally, I would start with Googling on the forum about issues with Pi USB ports - otherwise a more general search.
I’ve found nothing so far… no errors during boot, doesn’t seem to use too much energy, nothing the linux logs around the time of failure that could give me any clue…
Unplug and plug the dongle doesn’t seem to work but restarting the system usually does.
Now I’m testing having just the Zigbee dongle connected, nothing else but the first attempt didn’t go well, it just didn’t get online. I’ll leave it all night and see what happens.
So I finally accepted that it won’t work and asked for a refund (still fighting with the vendor) and bought a telegesis that it’s not working either, I’m gonna cry
Sadly I have no screenshot and log in hand (log does not show it anymore) so I cannot tell precisely. I will collect them next time.
It was something like communication error on the dongle. The dongle status in paperui was grayed out and the related Zigbee nodes as well.
A rule could dis/enable the dongle as this step was always resolving the issue in my environment.
Ps.: Recently upgraded to the latest stable OH.
Update: @chris in the log I can see this
ASH: ERROR received (code 81). Disconnecting.
Would you need the full log or only a slice of it (if so, what time range before after the event)?
Is a regular log enough or should I set something to debug level? If yes, what exactly?
I’m fairly certain this isn’t related to general undervoltage or the like, as this behaviour is also apparent with my Intel NUC.
It might be related to USB power saving, but since the ember coordinator is also listed as “state UNKNOWN”, I’d wager it’s some kind of communication issue.
Hi,
This is a pretty old thread - can you explain what issue you are having, and what versions of bindings etc you are using. I’m not sure what your reference about undervoltage is as you’ve not referenced a previous comment…
Sorry - but it’s very difficult to help you with no information on the problem you’re having.
As per my response to the other thread you posted, please check out the documentation as this device may require additional configuration to be recognised.
