Adverting mode changing from BLE_ADV_EVT_FAST to BLE_ADV_EVT_IDLE. Could you provide example for changing adverting mode from BLE_ADV_EVT_FAST to BLE_ADV_EVT_SLOW mode?

Hi.
Closing this as a duplicate:
How to configure for changing advertising mode slowly?
Let's discuss your issue in the other ticket.
