The timeslots I referred to is a SoftDevice API feature that allows you full access to the radio etc for a given time period. You can refer to the timeslot documentation for details if relevant. Your original question was quite spares though, so I cannot say for sure if this is relevant for you. I suggest you elaborate / explain more about your original question if you want better help.

Hi,

This depends on several factors, not least which SDK variant and version you are using. Can you explain?

If you use the nRF5 SDK and SoftDevice the SoftDevice itself supports being disabled and then re-enabled. However, several of the SDK libraries are configured for using SoftDevice or not compile-time, and the SoftDevice handler library supports initializing the SoftDevice, but does not handle re-initialization out of the box. In sum this means that you need to make quite a few changes in SDK code in order to support disabling BLE and using proprietary radio without a reset. Other alternatives is to do a soft reset when switching, if that works with your application. You can also keep the SoftDevice enabled, and use timeslots.
