Description: I want to use the HR data broadcast by a Polar H10. I am able to retrieve the advertisement data and the Manufacturer data of 4 bytes. It seems that the last two bytes are HR values (u8) ? But what about the first two bytes ? At first I thought it would be some RR signal but after converting to u16 it doesn’t make sens. Any tips ? Am I correct for the last two ?

Hi, Did you figure it out? I have the same question and can't find the answer anywhere. And yes, I think you're right about the 2 bytes with HR data.

Still not found any documentation about it. But, yes it's R-R data in little endian format (2x u8 -> u16).

Super, thanks!
