Hi,
I hope this is the appropriate forum for this question. I've also asked this on the developer forum on thisisant.com, but received no answer there.
We are using Continuous Scanning Mode for our application, BigRingVR. This works very well for most users, but some users are reporting that their ANT+ sensors are not detected.
This happens on different ANT USB sticks, on different OSses. There is one user, using a 2moso ANT Stick, for which it works on Mac OS X, but not on Windows 10.
A trace of the ANT messages is below:

2017-10-06T05:01:14.001Z: OUT [a4][01][4c][02][eb]
Everything seems to be working fine, scanning mode is started:
2017-10-06T04:42:13.046Z: IN [a4][04][40][00][5b][00][bc][07]
But directly after that, this message comes:
2017-10-06T04:42:13.603Z: IN [a4][04][40][ff][01][01][18][07]
after which the channel is closed by the stick. In the ANT Protocol document, I cannot find the reason for getting this message and also cannot find what it means. As channel is 0xFF, it's probably meant for all channels, right?
Help is very much appreciated! Thank you, Ilja Booij BigRingVR.com
