Same here. We've been using Ubertooth One and it was not a pleasant experience. Certainly cheap and easy to set up, but with very mixed results. Not only does it miss connections due to the channel hopping, it also frequently loses connections, which is even more frustrating. We've had the privilege to know someone with a professional wide-band solution (Ellisys Bluetooth Explorer), and it was miles ahead, including the analysis software.
