Does Nordic provide an API to get connection event counter

I suggest to take a look at this case:
https://devzone.nordicsemi.com/f/nordic-q-a/61403/connection-event-trigger-and-timeslot-api

"The event trigger task is triggered when the radio starts ramping up before the first reception or transmission in a connection event. That is, 40 us before the first radio activity."

Is there a way to tie the BLE adapter’s clock to a specific point in the CE like what ONSemi described? also if I use sd_ble_gap_conn_evt_trigger_start where is the CE actually triggered? our peer device will grab its clock at the start of the first RX window in each CE.

The only api available is the one already linked sd_ble_gap_next_conn_evt_counter_get Whether this will fit your requirements is difficult for me to comment on.

what i actually expect is when the connection event occured, i can have a way to associate it to the timestamp.

can I use the sd_ble_gap_conn_evt_trigger_start to implement this requirement? So I'm thinking can I use the PPI

to associate the connection event with a gpio task, then in the gpio interrupt handler, I can assign a timestamp to it?

Hi,

there is a sd_ble_gap_next_conn_evt_counter_get function in S140.
