A SoftDevice is software which implements a wireless protocol and the nRF51 and nRF52 series specifically mention them. Since the nRF5340 has a dedicated network processor does that imply a SoftDevice is not used by the nRF53 series?

Hi,
For the nRF53 series we are no longer providing a SoftDevice. Instead we are providing a SoftDevice controller as part of the new nRF connect SDK. There is a blog here comparing the two. As well as some more blogs and tutorials here: https://devzone.nordicsemi.com/nordic/nrf-connect-sdk-guides/
The latest nRF connnect SDK documentation can be found here: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/index.html
Hi run_ar, this info is useful. However the latest documentation does seem to mention SoftDevice. If this is no longer true, it would be great if it were updated. Thanks!

"...Currently, the nRF Connect SDK provides the following solutions for the network core:
Bluetooth LE Controller - both the SoftDevice Controller and the Zephyr Bluetooth LE Controller...."
Hi,
As mentioned this is the "Softdevice controller". Compared to the traditional Softdevice this is only the Controller part.
So for nRF52 series we provide a Softdevice binary that has a qualified controller (link layer) and host layer.
For nRF53, we provide the Softdevice controller (only link layer), which has to be combined with a host layer, i.e. zephyr host or BlueZ linux host. See https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/ug_ble_controller.html#softdevice-controller
