Problem with the Polar Heart Rate Monitor Interface

Hi,

I recently bought the Polar Heart Rate Monitor Interface and wanted to link it with my Arduino board.

I tried to copy the code of the manual Appendix B (Arduino using I2C) into my Arduino, and I removed the SJ1 jumper. (I hope it is totally removed, I don’t see a connection anymore)

But it doesn’t work…

I can see the led blinking on the Polar module , so it has a connection with my belt, but I don’t see anything in the serial monitor of Arduino.

Can somebody help me ??? What am I doing wrong ???

Thank you!!

Kind regards,

Hans
