BT5.2 nrf SDK17 or nrfConnnect

[nobody_19]

Hi 

I heard in the "nRF Connect SDK" presentation from May 2020, that the nrfSDK only support BT 5.0.

• Is this still correct that the features of BT5.1 and BT5.2 are not supported in the nrfSDK?
• Is the 5.2 from nordic already released? Or when it is planned to release?
• Is there somewhere a pro/cons list (or something similar) between nrfSDK and NRFConnect?

• Is there a Debug and Trace example for the nrfSDK and nrfConnect available? 
• Is there a  hardware difference between nRF52840 DevKit Rev 1.0.0 and Rev 2.0.0? Or only a software difference which can be programmed?

Thanks in advance for the answers.

Is this still correct that the features of BT5.1 and BT5.2 are not supported in the nrfSDK?

The Bluetooth Low Energy protocol stack can be found in our SoftDevices or in the nRF Bluetooth LE Controller for NCS. The latter includes the Link Layer from the Nordic Softdevices. NCS is based on the Zephyr project RTOS, which also includes is own Bluetooth stack. Running an RTOS allows more advanced features.

Is the 5.2 from nordic already released? Or when it is planned to release?

No, unfortunately, there is nothing available on DevZone. Your RSM may have something. 

The nRF5 SDK is more mature and supports the nRF52 series. 

The nRF Connect SDK (NCS) is fairly new and has more support for our newer devices i.e. nRF9160 and nRF5340, and, at the moment, less support for nRF52 series.

Is there a Debug and Trace example for the nrfSDK and nrfConnect available? 

 I recommend looking through our examples in the nRF5 SDK and NCS.

Is there a  hardware difference between nRF52840 DevKit Rev 1.0.0 and Rev 2.0.0? Or only a software difference which can be programmed?

 No, there should not be any noticeable differences for you from rev v1.0.0 to rev v2.0.0. 
Edit: The changelog for the nRF52840 DK HW files, found here, has a more detailed answer.

Kind regards,
Øyvind

So If I understand it right the Softdevice BT Stack is not the same as the Zephyr BT Stack. So then still the question is open till the softdevice BT Stack gets some new BT features, like the 5.2 features (or 5.3 features). 

Is there a plan to also support on the softdevice BT5.2?
