Hello,

As Turbo points out, the Softdevice reserves access to certain peripherals such as POWER and RADIO when enabled. A full overview of resources which are restricted or blocked to the application can be found in the "System on Chip resource requirements" chapter of the Softdevice specification.

If you need to clear bits in the RESETREAS register after enabling the softdevice, you must do so via the sd_power_reset_reason_clr () function.

Best regards,

Vidar

Softdevice has its own functions to access (parts of) restricted peripherials. You can see what is restricted (or blocked) in the softdevice specification.

No idea if that stuff is still online, SDK is no longer supported.
