ANT+ and Bluegiga USB Dongle

What is the difference between “ANT+ MINI USB STICK" and"BLUEGIGA USB DONGLE


The first one is an ANT+ dongle and the second is a Bluetooth dongle.

More then likely you will need the first one, but it’s hard to know without more info on what you are looking for.

Thank you for the information. I am going to connect my PC to the Cycle ops Hammer

You will need the Ant+ dongle to Connect the trainer to Zwift on a PC.

… Yes (ant+). When (if) you want to update the firmware on your Cycleops Hammer, that’s when you use the BlueGiga dongle and the rouvy app (or whatever Cycleops’ app is called at the time).
