ANT Forum

Hi,

I got a question, i can't find the answer for me.
I want to calculate the speed and candence. I find the formulas, but i did not find how to process the message(which bytes) and which message.

I read something about every 65th message, if so does it matter which type of message?

I hope someone can help me with this.

Best Regards,
Klaasjan      

Hello,

The ANT+ Bike Speed and Cadence device profile describes how to calculate speed and cadence data, as well as how to interpret the data pages.

Please have a look here.
