我終於有點搞清楚Hero4所謂的藍牙系統了....
看起來是待機時WIFI會關閉省電，但是傳輸時還是得靠WIFI，但是操作時開著WIFI應該還是很耗電吧...？！

Let's Clarify!
Bluetooth is only used on iOS during the INITIAL PAIRING PROCESS to help isolate the connection, save battery life during pairing, and to make the camera more easily discover-able to the device/user
Once the initial pairing process is setup, the GoPro iOS App switches from Bluetooth back to Wi-Fi, it does NOT"Connect + Control" using Bluetooth. This is because Wi-Fi has better bandwidth, security, and range than Bluetooth.
On your Android device, simply initally pair using Wi-Fi and the connection will be retained when you are ready to use "Connect + Control".
In summary the end result is that both the iOS and Android App from GoPro still continue to use Wi-Fi for the connection between the camera and your smart device.
*************************************************************************************
Bluetooth connectivity on the Hero4 is solely for extending battery life while WiFi is on.
It takes much less battery to power a bluetooth signal compared to a WiFi signal. So the wifi connection is off while the camera is off but in wireless mode, and the bluetooth remains on so that the iOS can send a signal to the bluetooth to turn the WiFi signal on.
The only advantage of having an iOS operate a GoPro remotely is a slightly extended battery life.
