How to connect wii balance board with android

Question

I found this answer useful: Is it possible for an android device to read information from the wii controller and nunchuck? (quoted below with thanks to @Ben Mordue)

Have a look at this open source project: http://code.google.com/p/android-bluez-ime/

Update:

I first installed the APK file on Galaxy Nexus and it works. I have checked the code out of the repo, and it builds fine, and it relatively easy to understand.

It comes in 3 projects - to use Wiimote, you need to install all 3 projects. The one is just used as a flag to allow the service to try for a Wiimote (considering not all ROMs support that level of HID interaction).

I also found these resources on WiiBrew.org:

I used the Wiimote link to understand the Bluez-IME code.

Update 2:

Last night I got the board to communicate with my Android phone correctly. I did this by starting with the Bluez-IME code linked above, and modifying it based on the wiibrew.org info.

The trick is that the Balance Board is like a wiimote with an Extension. So its like a Nunchuk or Classic Controller, but just with a different device ID to look for.

For my initial demo, I just searched for all code that uses a Nunchuk, and duplicated it for a Balance Board. Then to initialise the MODE to use channel 0x32, as per the wiibrew Balance Board page.

Update 3:

I just stumbled across this app on the store: FitScales

And the developer has shared his code on github: paulburton / fitscales
