SCANNING ISSUE nRF52840

[Aylik]

Hi All,

My Server send ADV packet every 1.4 seconds.

Scanner (Peer) scan wiht parameters : 2000ms(period) / 1500ms(window).

WHY  CONNECT happens only each 6 seconds  not 1.4s ? The behavior is: Peer connected, then read some Server data then disconnected (~ 100ms for all operations).

How to set correct SCAN parameters (for 1.4s ADV) to do CONNECT every 1.4 s ?

Please explain how to SCAN works.

Hi,

You might be unlucky and all the three first advertisements fall outside the scan window. Have you tried setting scan window and scan interval equal? Please have a look at this blog post about how advertising and scanning works.

Best regards,
Jørgen
