Why the ble_app_hrs_c can not scan the Polar H7 Heart Rate

[Vincent]

Hi, I use nRF52832 with sdk 12.2. and I running the ble_app_hrs_c example code on pca10040 evb. I can scan many hr devices but polar h7 heart rate not. I check Iphone and Android phone those cell phone has installed the nRF toolbox and can scan the Polar H7 device. Does central device scan has some parameter need to set?

Thanks

I also test the SDK12.2 central scan the Wahoo Speed and Cadence Sensor. The Cadence can be scan only. If I use nRF51 SDK10 central scan I can scan Wahoo Speed and Cadence. But SDK10 and 12.2 can not scan the Polar H7 Heart Rate belt either.

Can you use a sniffer to check what is advertised from the polar H7 belt? I would guess that you don't get a match when checking the adv data.

I dont know how to use sniffer and use this for check. Where is sniffer Document?

You can find the nRF sniffer here. Another option would be to use nRF connect on pc/android/ios to see what is advertised from the H7, or maybe just print adv reports from your application.

Ok, I will study Sniffer ..... But I do print adv report from my application. and i can printf most device name and mac address I have...but polar and wahoo speed sensor. If I can use sniffer to check polar and wahoo adv after that what I should I do modify some scan parameter or do something. Thanks
