Found this thread by following the various Android & Ant+ threads.
If this is not the right place to post, please let me know where I can repost this question.
I have a Huawei MediaPad T5 that has EMUI 8.0 (a variant of Android 8.0)
I have all ANT Radio Service, ANT USB Service and ANT+ Plugins Service all installed. I also have the ANT Tester app installed.
I also have Zwift v57540-1.0.57540 installed on this tablet.
I also have the ANT+ Plugin Sampler, and using this, I can confirm that the the OTG cable and Dongle are both working and that I can receive telemetry from both my Kinetic InRide 3 and Garmin Cadence Sensor (Model: F4ECNA01).
However, when I open up Zwift, and attempt to locate these devices to pair them using ANT+, the pairing screen just sits there, seemingly stalled saying “Searching…”
So this can’t possibly be a hardware issue, since I get telemetry from ANT+ via the Plugin Sampler, and I’m at a loss as to why Zwift can’t locate these (or any) ANT devices on this tablet.
