Could you please enable the inclusion/exclusion list capability to ANT+ pairing process, or is there any other way of selecting a device in a situation where multiple sensors are within the same proximity?
For the time being the best option will be to set the proximity bin of the channel to a small enough range to allow for a proximity pairing experience.
However, I do understand the need for inclusion/exclusion list capabilities to make the pairing process easier when there are multiple sensors close by. I'll log this feature request for a future release.
