RE: Central Connection Interval Schedule & Latency Issue

Hi,

What is the configured tolerance and source of the LFCK used here (on peripherals and central)? Any improvement if configure 500ppm?

To avoid scanning take precedence over active links, try to scan as often as possible, e.g. interval 10ms and window 5ms.

Also check out:

"The probability of collision can be reduced (though not eliminated) if the central role link parameters are set as suggested in this section, and the following rules are applied for all roles:"

I think you need to have a larger interval than 55ms here, e.g. 60ms due to tScanReserved.

Best regards,
Kenneth
