Devices depart from the 1 Wire network unexepected

[gordijn]

Hi,

I've recently bought a master hub from hobby boards for one wire and after a few hours running, the device
(I have only one, the battery monitor) departs from the network unexpectedly.
Also, I see that the switches in the hub itself depart from the network.

I am using the Java API, and RXTX on Linux.

Every now and then, I get the following exceptions:
Exception: com.dalsemi.onewire.adapter.OneWireIOException: OneWireContainer26-Bad CRC during read.99
Exception: com.dalsemi.onewire.adapter.OneWireIOException: OneWireContainer1F verify on command incorrect

Please advise.

Best regards,

Jaap,

Sounds like there could be a problem with your Master Hub. Can you use the OneWireViewer and see if the problem still happens so we can rule out a software problem.

Hi Eric,

I have done several tests, and I think that my hub is not working well.
I get many times the error OneWireIOException: OneWireContainer1F verify on command incorrect,
and after a few days, I get the error Exception: com.dalsemi.onewire.adapter.OneWireIOException: Error communicating with adapter.

If tried it two different computers.
I also get hangups if i use the OneWire viewer.

What can we do about this?

Best regards,
