Bluetooth - how does it work with Fitbit?

kah22

I have three devices: a Fitbit Charge HD  activity wrist band, a Galaxy s4, and an iPad Mini. Here is my confusion

The Fitbit gathers the activity information and, as I understand it, is suppose to pass the information on via Bluetooth to the other devices. What seems to be happening is that if I am in an area where there is wi-fi then the synchronization takes place. So my question would be does a set up like above need wi-fi to operate or should it operate independently? How does this synchronization take place anyway?

Thanks for helping me understand a little bit about how Bluetooth works

It only has Bluetooth not WiFi, it will only sync with FitBit servers with an internet connection available and a Bluetooth connection, well my ONE does, or you can go into the FitBit app and tell it to sync now, but it has to have an internet connection available as well or it will not do it, maybe it's only getting the BT and Internet with you by WiFi but it should do it with a reasonable strength Mobile Phone signal.

Will test it with my mobile later just to see what happens. Thanks for helping to clear things up in my mind
