Perhaps I misunderstood you. If you want to press a button during startup (after reset), and reset after exiting the specific mode, then you do not need to do any cleanup. However, if you want to switch to DTM after the SoftDevice have been enabled, then you should call sd_softdevice_disable() before you initialize DTM.

Hi sir

What is the specific method to disable softdevice?

It means to modify the parameter in the sdk_config.h?

Or set an button to switch the between them?

Many thanks

Hi,

It should not be a problem as long as you make sure to disable the SoftDevice before entering DTM mode, and make sure that you disable any interrupt sources before exiting DTM mode and starting the SoftDevice. The SoftDevice itself will configure all the relevant registers properly when it is initialized, so it does not relay on any registers having their reset/default values initially.
