Hi,

I am having problems to write to the server with the writeAsync method.. But the writeValue method works fine, with the same NodeId and value, this the code for writeValue:

NodeId nodeId = new NodeId(2, “MyLevel”); //DataType : Double
double vd = 15.5;
try {
client.writeValue(nodeId, vd); //————————-This method works fine!
System.out.println(“Value save succesfully to Node Id: ” + nodeId);
} catch (ServiceException | StatusException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

And this is the code for writeAsync method:

DataValue vdf = new DataValue(new Variant(new Double(vd)));
WriteValue arg0 = new WriteValue(nodeId, Attributes.BrowseName, null, vdf);
System.out.println(nodeId);
System.out.println(Attributes.BrowseName);
System.out.println(vdf);
AsyncResult r = client.writeAsync(arg0); //This does not work!
WriteResponse response;
try {
response = (WriteResponse) r.waitForResult();
StatusCode[] val = response.getResults();
System.out.println(val[0]);
//System.out.println(“Value save succesfully to Node Id: ” + nodeId);
} catch (ServiceResultException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

Error: Bad_NotWritable (0x803B0000) “The access level does not allow writing to the Node.”

—- The access level of the NodeId is 3, this is how I created it:

// My Level Measurement
final NodeId myLevelId = new NodeId(ns, “MyLevel”);
UaType doType = server.getNodeManagerRoot().getType(Identifiers.Double);
CacheVariable myLevel = new CacheVariable(myNodeManager, myLevelId, “MyLevel”, LocalizedText.NO_LOCALE);
((UaVariableNode) myLevel).setDataType(doType);
myLevel.setTypeDefinition(myLevelType);
myDevice.addComponent(myLevel);

I do not know what can be the problem, I am trying to write to the same NodeId and one method works and the other does not.

Thank you!
