Difference between NRF Sniffer and BLE Central scan code

[Sergy]

I have a peripheral device that sends an advertisement package with all the data I need every 5 seconds (sensor).

When I use NRF Sniffer via Wireshark I see a message from this device every 5 seconds (sometimes corrupted, like 1 per 20 messages) which is ok.

when I use scan from BLE Central example  sometimes I dont get any packets from the sensor for 1,5 minutes.

The question is whats the difference between the code or may be settings?

(also did a test with Zephyr central_bas sample code - also missing packets)

Thanks!

I'm currently looking into your questions and will try to provide an answer in the upcoming days.

Hi Simon,

With this one I figured it out, so will reply myself:

There is a difference in the scanning method between Sniffer and whats in S132 softdevice. And there is a packet loss happening due to the switch of the channels.
