So the new GoPro Hero 4 does not have a pure Bluetooth connection to the GoPro App. It is still WiFi. I would not suggest anyone with a 2.4 ghz Radio transmitter (Phantom 2 non Vision) use the Hero 4 with it's wifi/Psuedo Bluetooth turned on. The camera is still using WiFi. GoPro totally misrepresented the new Bluetooth feature for controlling the camera. I just got off the phone with GoPro and believe me, they are getting a lot of calls from Multirotor guys who are really pissed off. The support rep I spoke with even told me her dad just had a Phantom Flyaway after having the Hero 4 Wifi/Bluetooth turned on. I just needed to vent!!
