Some question about the fitbit dongle

Hello,

 

It's a really nice article, love it. It helped me to know more about the device.

I also have a fit bit and it works great, However there are some things i dont understand.

As it usages a NRF8001 and it is a Bluetooth Low Energy, So how is it able to sync with Dongle as well as the smart phone's? Is it the Dongle which helping to do this? Is the dongle Dual mode, so that it can talk with Classic Bluetooth as well as Low Power?

Also when i plug in the dongle in my laptop i dont see it as a normal bluetooth device it appears as a human interface device in device manager. Isn't the dongle a bluetooth device? If yes why doesn't it show up as a bluetooth device?

I am really curious about it and looking forward to hear from someone.

 

Thanks in advance :)

Hi Rich,


This teardown was extremely helpful to me.  I am conducting a reliability study with 20 Fitbit Zips using a mechanical step machine.  I have two questions.  The first is whether I can have permission to use the internal picture you posted (I would provide the reference back to this teardown and credit you).  The second is whether you would be willing to identify the exact location of the mems accelerometer on the board.  You mentioned it is a 3mm x 3mm part that can easily be mistaken for one of the passives.

For the article I am showing the teardown of an actigraph 7140 that used a piezo-electric type accelerometer and I want to show the insides of the zip along with a MIT schematic of the Capacitance Acceleromer. 

I look forward to your correspondence.
