CC2640R2F: MAX_NUM_PDU and connection intervals

Part Number:CC2640R2F

Hello,

I've set the connection intervals on my central and peripheral bards on 4 sec. And I have also set he MAX_NUM_PDU to 1. The peripheral sends 200 notifications, which are being summarized on the central and its sum is being displayed. I assume that theoreticly, the sending of 200 packages with 4 sec of connection interval and 1 packet per connection interval should take 800 seconds. But why then I have a sum displayed in under 2 seconds?

Regards,

Alen V.
