nRF Connect Bluetooth Low Energy application displays not all BLE devices

[SergeyV]

Hi!

I use nRF Connect Bluetooth Low Energy application for scanning. There are not all BLE devices on the device list.

The device that is not displayed on the list send Advertisement and ScanResponse packages.

Are you sure that the device you expect to see in the list is actually advertising? are you testing nRFConnect on desktop or the mobile phone. I haven't personally experienced this but if I were you, I would check with the sniffer to see if the device (not listed) is actually advertising or not.

Yes, I'm sure. the device is advertising. Other BLE devices receive packages from the device. I'm tetsting nRFConnect on desktop

[Susheel Nuguru]

that is strange. I have not heard this before, You see few other devices advertising around you but do not see one specific device? can you install nrf connect on your mobile phone and see if your device appears there?

Yes, that's right.

Mobile application displays less devices than its desktop version

It is hard for me to understand why this is happening. If your advertiser is close enough, then surely it has good signal strength. 

Can you give me the hex file for the advertiser so that I can run it on our DK and see if i can reproduce it.
