Just to add to the discussion: I also recently purchased an Airturn BT-500 to replace my aging BT-105 that started to become unreliable due to flaky connectors of the pedals. I've been using a Windows-based tablets with MobileSheets for a couple of years, and never had any problems. But I could not get the BT-500 to work correctly in any mode, even though pairing did seem to work. I'm also very sure it's a Windows/BT-500 related problem, since the BT-500's pair and work perfectly with my (very old) Android-tablet and the Android-version of Mobilesheets. I also bought an Airturn PedPro in the meantime that works perfectly with the Android tablet AND the Windows-tablet.

Something I've noticed: All of my other Airturns show up in the keyboards-section in the Bluetooth-settings, but the BT-500 gets put under the "other devices". The icon showing which type of device it is, is also different from the other Airturn-pedals, namely a keyboard+mouse (desktop-set) instead of just a keyboard with the working pedals. My best guess is there's something wrong with the driver that the BT-500 gets assigned in Windows, or there's a bug in the firmware that only shows up in pairing with Windows.

Here's to hoping they fix the error soon. I really prefer the tactile pedals of the BT-500 to the pressure plate of the PedPro's, since with the latter I regularly get missed presses that really take you out of focus while playing.

i have sent it back to thomann.

Too bad you've already sent it back. I've experienced the same thing about 15 minutes after opening the BT-500's box by just doing a hard reset (based on the manual's instructions), and I've gotten pretty thorough steps from Airturn Support (that are not mentioned in the manual) to recover a BT-500 that's in such a state. It worked perfectly for mine either way, although they're still not working on Windows as described earlier.

Do you feel confident enough to share the un-printed steps?
Does anyone have a BT 500 working with Windows10?
