Hello,

Weekly I'm facing troubles with my Z-wave Stick, stick is dis- & connecting continuously.
I've tried to understand why it's happening, but couldn't find a good lead.
Are you familiar with this problem?

Suddenly it's stopping and everything is working fine without any problem.
Stick which I'm using is recommend type as described model(Aeotec Z-Stick) in the help file.

In my Win8 log file doesn't appear to be a problem with the stick or usb controller. I assume it's a software issue from bOS.

see attached print screen of log.

Any support is welcome.

Thank you in advance.

Best regards,

Fred Hartman

I'm having the exact same problem, but reducing the buffer only resolves it for a few seconds, could anything else be causing this?

Hi Jure,

I've located the cause of the problem, if was the buffer setting of the Z-wave stick.
After decreasing the buffer, the problem didn't occur again. I've tested it with several settings and the settings as showed in the print screen below are working fine.


So you were right it was hardware related.
Thank for your support so far.

Great! Also thank you for sharing the solution.

Hi Fred!


This is the first time I've seen an overrun error while working with zwave. I've done some research and it appears this is a hardware problem. The zwave dongle is not clearing its buffer fast enough to receive all the data, hence the error. Because of this I can't do much from my side. The only solution I can think of is to try installing a different dongle.


Sorry for the inconvenience.

Jure

Hi Jure,


See printscreen of retrieved info from monitor. Do you need more information or is this sufficient to fix it?
If needed you may acces my BOS server to check settings or errors.


Thanks for your support!

Hi Jure,

I'm using Win8.1 as well. I'll activate the monitor, including the requested settings and forward it within some days, so you can analyze the log file.

Hi Jure,

I've downloaded the software from the provided link and executed the firmware upgrade of the stick. drivers from usb-bridge controller software were not updated, so still version 6.7.0.0. (CP210x USB to UART Bridge VCP Drivers)
On the website of silicon labs (Link to driver page) I checked for latest version, there's no newer update available, 6.7 is latest.

Could you send me version 6.7.0.1 by email? or we.transfer.com

Thank you in advance.

Regards,

Fred

I just checked on a Win8.1 PC and the version is the same as yours. So that shouldn't be a problem. I think the next step would be to send be the monitor output.

Hi Jure,
I've done the soft reset for three times over the last three weeks, but it didn't solve the problem. I'll try to update the firmware version first. I'll keep you updated.
Thanks for your support.

This is the stick which I'm using.

Aeon Labs DSA02203-ZWUS Z-Wave Z-Stick Series 2 USB Dongle


I've bought by a local dealer in the Netherlands.

Current driver version in my Win8 system, see details below.

Hi Fred,

so I've checked a few things and noticed the driver version is different, I have version 6.7.0.1.

First do a soft reset on the device. There's a button in the Network Configuration form. That will reboot your z-stick. If that doesn't work try to update its firmware.

If this doesn't solve the problem I'm going to need a bit more data. So firstly, turn on 'Debug Mode' in Zwave main node. Then turn on the Monitor tool(bottom left). Click 'Filter' and select the Z-wave node. The 'Record' button should be blue, if not, click it. This will record all the communication between bOS and the dongle. Leave it for a day or so, then save it and send it to me.


Regards,

Jure
