I use two nRF52840 to send notifications every second. Analysis using a logic analyzer revealed that the reception interval had strange variations. What is causing this? Why is there a gap at 1 second from the reception?
connection interval 10ms.

connection interval 10ms.
The program is based on the sample ble_app_blinky and ble_app_multilink. The connection interval defined MAX and MIN on the peripheral side.
For the notification of every second, the timeout was set every second using app_timer.
I also wanted to know the time it takes to send and receive, so I switched GPIOs just before the peripheral sd_ble_gatts_hvx and at the beginning of the on_hvx in the central, and observed. I wanted to check it as low as possible, but that was the limit I think.
This graph is the time from the transmission pin to the reception pin which I set measured on the logic analyzer. The time is [ms]. I am worried about the strange law of delay.
I'm sorry for my bad English．
