Why is pairing taking so long?

I am using the stm32wb55 as a Central.

When pairing to my server, I encounter long pairing times.

About 80 seconds from the moment I send the passkey to the time I get paired complete event.

.

(I have no errors in the pairing complete event)

I did not have this issue with my previous device. Pairing has always been done quickly.

Please tell me if I might be doing something wrong. What might be prolonging the process?

Hello,

Is this delay increasing depending on the number of connections in your setup? Which connection interval are you using?

Thanks. I checked and the connection interval was way too long, after changing it all works fine.
