I try.
I followed more or less the same procedure as the opc-ua driver.
In the main class I implemented the driver and ConfigurableComponent interfaces.
I created the ChannelDescriptor based on what I need to use.
In the driver class I inserted some logs in the read and write methods.
On kura, I create a channel and set it in read_write mode. I expect the logger to print the write part to me, but instead I print the one related to the read.

public final class Eu63Driver implements Driver, ConfigurableComponent {

    @Override
    public void read(List<ChannelRecord> records) throws 
    ConnectionException {
		logger.info("READ");
    }

    @Override
    public void write(List<ChannelRecord> records) throws 
    ConnectionException {
		logger.info("WRITE");
   }
}

I entered the parts of the class I told you about.
I think something is missing because opcua instead does it.

The write operation is performed only if the request that triggers the asset is associated with a metric that has the same name and type of the channel defined in the asset.
