When we implemented Bluetooth connectivity in our Windows app a long time ago, there were so many PC devices with differing levels of Bluetooth connectivity, and many PCs didn’t even have Bluetooth hardware yet. Because of the amount of work it would require to make the app’s device layer communicate with all the possible devices out there, we decided to just support the Bluegiga dongle at the time.
Bluetooth has since become equally prevalent as ANT+, and we’ve worked to support it natively on iOS, Android, and Mac, yet we haven’t been able to address it for our PC users. When Windows 8 was released there was hope of being able to connect to Bluetooth devices through that OS, but if we would have implemented our solution using Windows drivers for Bluetooth dongles, this would have only worked on Windows 8. We’re planning a full revamp of all of our apps, and one of the key pieces we plan to address is Bluetooth connectivity on Windows.
I hope this helps explain your original question, @isaac124! I’m sorry we don’t yet have a better solution. For now, the other comments in this thread contain good advice for how to get all your devices working together.
