Connecting FRDM-KL25Z to Arduino and Bluetooth Serial

Hi, Recently i connected my wild thumper controller (arduino) to my andriod phone via bluetooth and now my lecturer says I should connect the bluetooth serial to an FRDM-KL25Z which will send data to the arduino. Please does anyone have a simple mbed code to receive data from a bluetooth serial and transmit it?? here is a link to pin configs of the FRDM-KL25Z if needed http://mbed.org/media/uploads/rikabel/kl25z-pinout-revised.jpg . Also, are the rx/tx pins on the FRDM-KL25Z operating at the same voltage as the rx/tx pins on my wild thumper controller? Thanks for the help.

/media/uploads/kosidinma/mbed.c Ok so i managed to write up a code but i have no idea if its correct (i can't test it because my FRDM-KL25Z isn't here yet). Please can someone check it and see if its correct? Thanks.

Hello Kosy Onyenso,

have you added KL25Z as your board here? In order to be visible in the online compiler, you can add it here http://mbed.org/platforms/KL25Z/

You can compile your code, even without a board. Once it arrives, just flash it. Happy coding!

Thanks but the above code is giving me errors

Any idea on how to fix it?

Maybe mention which errors you are getting...

Anyway I guess it is something like: "Expected a ';'". Your last line of regular code lacks a ;. Btw you should take into account the KL25 is not 5V tolerant, you may not put I/O voltages above 3.3V on it.
