Cores & extreme sensitivity to Bluetooth interference?

Anybody here experienced the Cores being extremely sensitive to bluetooth interference? The Photons seem much more tolerant of sharing the airspace with Bluetooth.
Ideally I’m after comments from people who have (or have not) actually experienced this, rather than more generic helpful comments about the likelihood of this being the case due to the generally ‘better’ WiFi chip on the Photon.

Yes, I have experienced this with Cores and some cheap BT Mice, whenever the mouse was moved for some time the connection of the nearby Core dropped out.

Since WiFi and BT are both running at 2.4GHz and older or cheap hardware often doesn’t implement congestion avoidance schems that’s not surprising. TI’s C3000 is definetly one of the older devices.
