BLE PHY and connection time.

[Ziyao Zhou]

Hi

Whether the physical layer (PHY) of BLE affects the time from advertising and scan response to connection establishment?

[Edvin]

No, increasing to 2MBPS will not speed up the connection process. increasing the advertising interval and scan window will decrease the time it takes to connect.

Do you have some more context? Do you have a peripheral and a central that takes a long time to enter into a connection? Are they located close to one another? Do you control both devices (meaning they are both DKs and you have built the code for them)? Or are one of them 3rd party (like a phone or some other product)? 

BR,
