Trying to connect to 2 tags at once

As mentioned over in the Node-Red side of things, I’m having issues connecting to multiple tags at once.

The second discover never happens. I’m wondering if the discovery phase is shutdown by the connect call. If so I guess the only way to do it is to call discover all, save the list of discovered tags and then connect after a suitable time out period?

var SensorTag = require('sensortag');

SensorTag.discoverByUuid("34b1f7d136b9",function(tag){
    console.log("found " + tag.uuid);
    tag.connect(function(){
        tag.discoverServicesAndCharacteristics(function(){
            tag.notifySimpleKey(function(err){
                console.log(err);
            });
            tag.on('simpleKeyChange', function(left, right){
                console.log("button " + left + " 34b");
            });
        })
    });


});

SensorTag.discoverByUuid('1cba8c20caf3',function(tag){
    console.log("found " + tag.uuid);
    tag.connect(function(){
        tag.discoverServicesAndCharacteristics(function(){
            tag.notifySimpleKey(function(err){
                console.log(err);
            });
            tag.on('simpleKeyChange', function(left, right){
                console.log("button " + left + " 1cb");
            });
        })
       });
});

What I found is that discovering stops when some data is sent. This the case when you do connectAndSetUp. In order to fix that I do the following:

1. Discover All
2. On connect stop discovering
3. When connected start discovering again

You can find a test script at https://github.com/martin-doyle/SensorTagMQTT/blob/master/testSensorTag.js.

I could connect up to 5 SensorTags so far. Please let me know if that works for you.

Hi, I have two noble listeners one is listening only and another one is scan and connect. If Noble is scanning and then connect after that 1 connection attempts never automatically start scanning. I have to start scanning manually “Noble.startScanning()” after every broadcast. Is there any solution to prevent them. Thanks in advance.
