Fastest supported connection interval using the Coded PHY?

[Starbuck]

I'm trying to achieve a 10 ms connection interval using the LE Coded PHY.

SDK version 2.5.0

After implementing support for LE Coded PHY into our central application, I set the connection interval to 10 ms, but on the sniffer capture I’m seeing that the central (master) only checks in with an interval of 39.28 ms after every 3rd check in instead of the expected ~10 ms.  Any thoughts on why that would be?  My main.c is attached.

After looking at the event counter column, I'm pretty certain this is a limitation of the sniffer and not an issue with my code, but I would feel more comfortable if someone from Nordic would confirm.

Hi,

I agree, the sniffer is not receiving all packets as events are missing. It also looks like retransmissions based on SN/NESN, but it would be easier to say more with the actual sniffer trace/wireshark file.
