ANT Forum

Hi,

We are planning to design a watch that basically collects data from an ANT+ device (such as a heart rate monitor), then create a FIT file and then transfers it to a host computer via ANT-FS.

For this use-case, the watch would need to continually open one channel for ANT-FS to be the Client(Master) and then a second channel (on demand) for the ANT + device to receive real-time broadcast heart rate data.

My question is, if a channel is already using the ANT-FS network key. How would I go about opening another channel using the ANT+ network key? Wouldn't the use of a different network key reset all my previous channel configuration for ANT-FS? Is it not possible to have both channels operating at the same time with different network keys?

Greatly appreciate your help.

Thank You,

Harvey      

ANT allows for up to three network keys to be assigned to different channels on a device.

So it is not a problem to use both ANT+ and ANT-FS on different channels. Their configurations should not impact each other.

As for running both at the same time, this is not really a problem, but you have to keep in mind that the ANT radio can only be on one network at a time, so if you are in a long ANT-FS session, you will not be getting heart rate data during that time.      

I am also interested in simultaneously operating as a ANT-FS master and ANT+ slave. Did you have any success with your system?      

Yes, I believe that I just used the ANT+ network key for both the ANTFS channel and for the ANT+ sensors. Both channels can operate off the single network key.
