I dont take uuid and appearance in adv report now. I just take the device name and mac address because It will return error when you try to take uuid and appearance from Polar and Wahoo device. and I still have other problem and working on it. So have a nice day or night. c ya

Ok, I would usually just scan for a device with the services I'm interested in. But glad to hear it was a result of how your application filtered the adv reports.

I found the problem is Polar H7 APPEARANCE is worng. everytime I can the BLE device I will read the name, mac address and appearance in one function. but read the Polar H7 device appearance will got the NRF_ERROR_NOT_FOUND and stop my scan action. So that is why I can not scan the Polar H7 and Wahoo Speed Sensor.

Now I just use find_adv_name only. So I can printf every adv device the reason is my central device can not scan the polar. and after case BLE_GAP_EVT_ADV_REPORT: just find_adv_name and my print function only but polar and wahoo speed sensor just refuse show up. in the same time cell phone ios and android can very easy to see those device show up.

Thanks

Have you tried printing all the information in every BLE_GAP_EVT_ADV_REPORT you receive? Or are you using the find_peer_addr and find_adv_name functions from the sdk example first?

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

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.

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 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.
