Of course they interfere, Bluetooth and Bluetooth LE use the 2.4-2.48 ISM band, and so does WiFi. WiFi has up to 14 overlapping 20MHz channels, and Bluetooth 4.

Of course they interfere, Bluetooth and Bluetooth LE use the 2.4-2.48 ISM band, and so does WiFi. WiFi has up to 14 overlapping 20MHz channels, and Bluetooth 4.0 has 40 2MHz channels. Though I guess Bluetooth could be clever enough to avoid the channels with interference.
