I found the same topic without a solution (Jul 13, 2015, 04:06 pm).
I want to transform the ANT+ (or, if easier, bluetooth) Signal of my heartrate strap and send the HR to my treadmill which uses an uncoded ~5kHz Signal (like Polar T31).
How could I do this?
1st step for me: Getting HR to treadmill
Could I use an old uncoded strap and stimulate it with arduino? How could I do that? Just connecting the two pins coming out of the sensor with a relay would surely not work? (Haven't tried it yet)
I hope anyone has done something similar?!
Thanks for help!
P.s.: Of course I could buy a new strap which sends uncoded + ANT+ + bluetooth - that is not the question
