Hi,

Sorry for the late reply. Can I ask what is the end goal for advertising only once on each advertising channel?

In Softdevice controller has a feature called Radio notifications which you can use to notify the application when the radio is in use, perhaps it's something you can use for your application so you are sure that the advertising packets are sent before stopping advertising: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrfxlib/mpsl/doc/radio_notification.html?highlight=radio%20notifications
