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.

Ok actually everything is not that easy. Now that Im back to our normal application - our device has Central and Peripheral roles at the same time and I guess while advertising it cant scan, so the question would be how do we manage to maximize scanning time and minimise advertising?

Try setting the advertising interval to a really large value and set (e.g. to the maximum of 10.24 seconds), and set the scan window close to the scan interval to scan most of the time
