I spend alot of time then no success with plugin about cordova-plugin-zeroconf HOT 4 OPEN

Hi! There is an example app over here, and I see you have found this thread that contains some examples.

It should be possible to find the MDNS broadcast data from a NodeMCU device, and I suspect you might be having trouble searching for a particular type and domain. Are you able to find your NodeMCU device inside an MDNS search app like Discovery? If the zeroconf plugin app is searching for zeroconf.watch('_http._tcp.', 'local.', function(){...}) then the NodeMCU must be broadcasting at local._http._tcp. It's easy to get these backwards.

If you would like more help, please share you code for both your Cordova app and your NodeMCU device.

Thanks for your fast reply, I get results
zeroconf.watch fetch all parameters mdns devices
by the way, what is command to get ip address of specified device:
mdns name: echo
mdns port: 80
I want to get ip of address of it
is there any example?

The watch method in the README is close, it can be adapted like so:

zeroconf.watch('echo.', 'local.', function(result) {
    var action = result.action;
    var service = result.service;
    if (action == 'resolved') {
        console.log('service resolved', service);
        ipAddress = service.ipv4Addresses[0];
        console.log('my IP address:', ipAddress);
    }
});

I'm not completely sure this will find your service though. What is the full mdns hostname that your NodeMCU device is broadcasting as? It should be something like echo.local.

@emcniece
zeroconf.watch('echo.', 'local.', function(result){ }
it is not working to watch specific device
