I've done some work using ANT+ and a sensor on the simulator. Connect the ANT+ stick via USB, fire up the simulator and run your code.
Should that work on Windows 10? I connected a Garmin USB ANT+ stick, have several sensors active, but the ANT+ Sensors box in the simulator remains blank. I tested the ANT stick with a phone, and it is working. It is listed in Bluetooth & Other Devices as "ANT USBStick2" without further information. The app that is running in the simulator has permissions to use ANT and works correctly on a Fenix 3.
Also tried a Suunto PC Pod ANT stick, and for that Windows complains it can't find drivers, so I am assuming that that the Garmin ANT stick has the correct drivers installed. Reboot of system, reinstall of SDK didn't help.
Is there perhaps an error log somewhere to troubleshoot this?
