NRF52832 connect problem

[xiaosi1911]

Hi:

     I use heart_rate_collector project in pc-ble-driver (https://github.com/NordicSemiconductor/pc-ble-driver/blob/master/examples/heart_rate_collector/main.c)to connect my beacon.Now I can scan my beacon and create a connection success.But ,it takes me about 20 sec to create the connection success after scan and find my beacon every time.Do you encounter such case,and why?

    I delete scan process and create a connection by mac address,It create connection successfully in 3 sec.I think when the host find my beacon by scan and begin create connection immediately,the host will stop scan .Is it right? But why it effect the connect time.

 Computer platform:linux 
                                                                                                                            Thinks

Hello,

Can it be that the peripheral device have some whitelist enabled? Typically peripheral devices may start advertising with whitelist if they have bonded, and then disable whitelist after a period of time to allow for a new central to connect.

You may also try to set SCAN_INTERVAL=SCAN_WINDOW=0xA0.

Best regards,
