Hello
For your information, I had exactly the same issue with Cycplus ANT+ dongle. Replacing it with TAOPE ANT+ fixed the issue immediatly. Doing more research, I found the in my PC device manager, the cycplus ANT+ dongled appeared with a yellow exclamation mark. I tried to update its driver but it did not solve the issue.
Later, I saw also that on RGT Forum there is also a thread with the same excat issue!
Hope it helps…
regards
Pierre
