I have the same issues with Windows, even with a BT dongle I purchased (thinking it was because my built-in BT was too weak). On the exact same machine, if I boot into Ubuntu, the webide works flawlessly. If I forward the BT dongle to a VM in virtualbox, the VM webide works as well (but a bit slower than native Ubuntu).
I think it's just Windows being difficult. If you have a way to use a different OS, you should try it. A raspberry pi works as well (you can use the https://github.com/espruino/EspruinoHub project which also includes a hosted webide).
