Hey!

I just got a 6d Mark 2 and I have a couple questions I was hoping you could help me with:

1. Can you connect the camera to bluetooth ONLY?
2. Can you transfer photos using only bluetooth?

When I connect my camera to my iPhone 8 via bluetooth, it's telling me I need to connect WiFi in order to view images. That doesnt seem right....

Bluetooth has too low capacity for image transfer. But it's power efficient to maintain the connection during inactivity and then step up to WiFi during transfer time.

Okay, but what's the point of maintaining the connection? Do you run the Wifi all of the time?

Wifi is more power hungry. So there's a battery advantage in disconnecting between transfers.
But if you disconnect to the camera all together, you'll have a longer startup time when you want to transfer the next image. Thus the power efficient Bluetooth connection will stay alive all the time. When it gets a request, it will quickly wake up the WiFi connection, do the transfer via WiFi and then let WiFi go to sleep again.

Canon's idea is to give you the best from two worlds. Long battery life, quick startup and high capacity transfer. Well, reasonably high, at least.

After reading quite a bit on this and other camera implementations, the bluetooth appears to only be a constant bridge between your camera and your phone/tablet. As you want to do things with the camera from your device, those commands occur over the bluetooth connection. When data instensive things are needed, then the camera will turn on wifi for you automatically, connect to your device (provided you had it set up before), and then do the functions, and later turn off wifi to save battery life.

So the only time saved here is that the camera will automatically turn on/off wifi for you as needed depending on the functions you want to perform, while always staying connected via bluetooth for command and control back and forth. You no longer have to turn the wifi on/off yourself as you need it;with the bluetooth addition, the BT connection does that for you automatically now.

There is no wifi wakeup or sleep, there is only wifi turn on/connect and wifi turn off, so the lag involved in these functions still will exist.

Best analogy I could come up with would be two people are trying to set up AV equipment between two remote points, and instead of using AV equipment to communicate, they use walkie talkies to communicate timing and need between themselves, and those commands sometimes require AV gear to be turn on/off for video/sound feeds. The walkie talkie is the BT connection, the AV gear power up/down and transfer between two points is the wifi. Before the use of walkie talkies, there was just one person and they had to walk back and forth to turn things on and off as needed, or leave everything running all the time using up power.

It's correct that there's still a WiFi connect lag. But that lag tends to be shorter, when no person is involved, as no time is lost finding the right button to press, reading status messages etc.

This same question has come up before and every time it does numerous people are just appalled that both Bluetooth and Wi-Fi are needed, and they fight it. Why? Who cares what the camera does under the covers to make things work.

Appalled? Seems to be quite a bit over the top don't you think? Any post I have been involved in on 2 forums, people were more interested about what each will do, and how it impacts their remote access and control of the camera. I would say inquisitive or curious, certainly not horrified as you have put it. ;)
