Nintendo Wii Fit Board Questions

Hello, I need help “Hacking” my Wii Fit Board.

I want to use the UART pins
There is UART_TX and UART_RX.
I look on google and find nothing on how to make it work.

ALSO how can I make use of the J27H007 Bluetooth Module?*

Or can I just take out the Pressure sensors and use that?

*There is apparently a “Programmer” for it… But I cant find one.

Let me make a suggestion, get the Arduino Cookbook and a basic electronics book and read them. There you will find that Tx and Rx are output and input to a UART. The UART typically converts a 8 bit value to a data stream which can be synchronous or asynchronous.
