Is it possible to connect multiple heart rate sensors?

Is it possible to connect multiple heart rate sensors? For example monitoring the heart rate of four different athletes on one watch at the same time. So that "sensorInfo.heartRate" will be not overwritten by the connected ANT+ heart rate sensor. Or even to compare an external heart rate sensor with the internal sensor on the watch.

You should be able to do this if you use ANT directly to each one. So you don't use the standard interface to a HRM (with Sensor.Info)

Ok, cool. Do you know if it is possible to access also the Heart Rate broadcasting of another watch on the ANT Generic Channel? Or is this only possible when pairing?

I've done very little with ANT, but a watch broadcasting HR should look just like an HR band broadcasting over ANT. And I know that with ANT, you can see an HR band without pairing.

Another option here is that you have an app on each watch that send it's HR data using makeWebRequest to a common server, and then you can view the data on that server. Each watch would need a phone paired/connected to it.
