Unfortunately, I do not have experience using the BLED 112 dongle for anything except TrainerRoad 
.
Maybe someone on this thread has tried connecting BT headphones through the BLED1121 connection?
Hmm, that is fairly weird. This may be something best handled by our Support Team since they are extremely well versed in this type of issue. You can reach them at support@trainerroadd.com 
@Bryce thanks…I’ll email your team along with Wahoo.
I use a Wahoo ANT+ dongle with a Tacx Neo but have it on an USB extension cord so the dongle is right under the trainer. I set this up because my previous trainer (2017 KICKR) may have had interference problems… I was never able to completely confirm that was the issue but the extension cable was one remedy I tried and decided to stay with it.
The engineer in me abhors running a USB cable and going wireless for the last 6 inches of signal transmission. At that point, the trainer might as well just have an USB port and eliminate wireless entirely, but that isn’t an option for the current crop of smart trainers.

In my search for a BT dongle, I ran across something that states that the BlueGiga 112 is not the same as a generic BT interface. It certainly doesn’t come up that way in Win10.
I’m on an iPhone X, at home I have w Neo so can connect on Bluetooth no problem. The wattbikes at my gym are ANT+ only. What are my options to connect them to my IPhone X? What’s the best choice around at the moment.
I always use ANT+ dongle on a USB extension lead so I can put it closer to the trainer, not only that ANT+ can be read by multiple devices at the same time.
@TriathlonTom the modern way is to use an ANT+ to Bluetooth bridge. If I was starting over, would use this one:
4iiii Shop - USA/World: Heart Rate Monitors: Viiiiva combination Heart Rate Monitor, ANT+ bridge, and data recorder
These guys make a stand-alone unit, but that seems clunky in the gym:

I have an Wahoo ANT+ adapter, it uses the older 30-pin connector and that works for me in the gym with Stages bikes:
That’s awesome. Thanks for this. I was thinking there must be a more modern alternative to the pin adaptor and ant key!
So the wahoo key works with the latest iOS devices and OS now? I was under the impression earlier this year that something in recent iOS builds had broken the functionality.
If they work, I may change from Bluetooth to ant on my iPhone running TrainerRoad.
The Wahoo Key works as long as you have an Apple-Manufactured 30 pin to LIightning Connector. Many of the third-party adapters have the proper pins to transmit power and some data transfer, however, they do not have the proper hardware to continuously pass the ANT+ data into the TrainerRoad App.
The tricky thing is that Apple has now discontinued this adapter, so it is becoming harder and harder to find the adapter to make ANT+ work on iOS devices.
May I ask why you would want to switch from Bluetooth to ANT+? We find Bluetooth to be a more robust connection, and in almost all aspects, it is superior to ANT+.
Cheers!
Until last week I was running a needlessly complicated setup, trying to coordinate multiple services and run Zwift concurrently on a laptop with TR on the phone and I had a lot of conflicting BT issues that caused minor annoyance at times.
Since then I’ve decided that Zwift is not really worthwhile for my purposes and went back to TR on the phone with nothing else running.
I’ve added a Wahoo blue sensor to take over cadence and keep a zero speed alive since I’d been trying to negate the Kickr’s bogus distance/speed info, and think things may be settled out now.
Powermatch will take some getting used to but now it’s time to quit mucking about with sensors and software and work on the legs.

You can try BleuIO Bluetooth low energy dongle. its better if you are trying to connect to a pc mac or linux
In my experience, in addition to the BT dongle, you have to have a Windows computer that supports BT natively - a lot of laptops that started as Win10 machines do, some desktops that started as Win10 do, some laptops that started w. Win 7 or 9 and then went to 10 may work, and desktops that started as Win 7 or 8 won’t work. If you have any of these other machines that don’t natively support BT you can go with an ANT+ dongle instead but you’ll also want a long USB extension cord to get the dongle as close to the trainer as possible since the ANT+ signal isn’t as strong or reliable as the BT one.
