Hi,

I'm working on a connection driver that is actually subscribed to a device. Is is a good approach to configure it as an asset? In case it is, I was thinking in take advantage of the listen property already available in the WireAsset but I'm not sure that it should be used for this purpose.

Regards,

Hello,
what do you mean with "connection driver"?
Can you detail a little better what is the setup?

Best regards,
matteo

Hi,

I mean an implementation of org.eclipse.kura.driver.Driver. So far I've only created connections of type master-slave where I periodically request the data. What I intend to do is to perform a publish-subscribe connection with a device. Are the WireAsset and Driver interfaces the right option for this new approach? Is the field listen (of the ChannelRecords) expected to be used for this purpose?

Thanks,

An example of driver that can be used in listen mode is this one: https://github.com/eclipse/kura/tree/develop/kura/org.eclipse.kura.driver.ble.xdk
