Just got a fitbit force. My first instinct was to install the windows-only sync software in wine, but wine rates the software as garbage.

So I'll have to find another way.

I'm not alone trying to solve this problem: https://lwn.net/Articles/532410/

That makes it look like there isn't a very good solution.

Here is what the fitbit USB dongle looks like when inserted:

The comments in the article referenced above indicates that the current generation of fitbits are using bluetooth LE to transmit data.

treat the fitbit as a bluetooth device

A naive attempt to enable bluetooth in Ubuntu 13.10 does not work: No bluetooth adapters found.

Silly to hope that the base station is a generic bluetooth device. But if it were, I'd be able to do something like this to talk to the fitbit:

hcitool scan
bluez-simple-agent hci0 00:11:12:09:XX:XX
rfcomm bind rfcomm0 00:11:12:09:XX:XX
screen /dev/rfcomm0

Here's what I see:

root@ferret:~# hcidump
HCI sniffer - Bluetooth packet analyzer ver 2.5
Can't open device: No such device

snoop fitbit usb traffic

lsusb shows it here:

Bus 004 Device 002: ID 2687:fb01
