HR Strap Signal Strength

Hi,

Is it possible to get the signal strength from the HR strap? So you can determine which strap is closest to the receiver?

Thanks

What you are looking for is proximity pairing. See ANT AN Proximity Search in our developer documentation: https://www.thisisant.com/developer/resources/downloads/#documents_tab

Thank you for the reply,

I am currently using continuous scanning mode to get HR's from numerous HRM devices. I am wanting to display a list of all of the detected HR devices ordered by signal strength, so the user can determine which strap is closest to the receiver in a crowded environment while still being able to see all of the other straps that are detected. Is this possible in continuous scanning mode?

The documentation states that you set which "bin" you want to limit your search to when you open the channel. Is there a way to iterate through the bins that you are limiting your search to so you can determine which HR devices are in which bins while in continuous scanning mode? Or would the only way be to open a channel with bin 10, note all the devices detected. Then close that channel and reopen at bin 9, note all the devices detected and repeat the process until you reach bin 1 and then determine which devices were detected in which bins?

Proximity Search limits your search to a bin, or relative nearness. You may want to take a look at ANT AN RSSI Extended Information in our developer documentation: https://www.thisisant.com/developer/resources/downloads/#documents_tab RSSI .is the relative signal strength for each received message. You may then use RSSI to order the devices, which can roughly approximate nearness.
