Nrf5340 soft device backward compatibility

[Akshay Goyal]

Hi Team,

Currently we are using 52840 soc with softdevice s140_nrf52_7.0.1_softdevice.hex.

We want to migrate to 5340 for BLE 5.2 features, we would like to understand below points.

1. is it possible to use the same softdevice(s140_nrf52_7.0.1_softdevice.hex) with 5340 soc without any application changes.

2. if any other latest versions of softdevice is recommended for 5340. if yes, is it backward compatible with softdevice(s140_nrf52_7.0.1_softdevice,hex).

3. From where we can find the supported examples and SDK's or any third party libraries for direction finding(AOA and AOD).

Thanks,

Akshay Goyal

Hello!

Thanks for reaching out. The answer to your first two questions is that the nRF5 SDK SoftDevices are incompatible with the nRF5340 and there is no plan for any compatible release. The nRF5340 is designed to be used with the nRF Connect SDK (NCS), with either the Nordic SoftDevice Controller (not to be confused with the nRF5 SDK SoftDevices) or the Zephyr Bluetooth LE Controller (open source) as Bluetooth link layer. 

NCS has the "Direction finding connectionless beacon" and "Direction finding connectionless locator" samples. Though there is currently not implemented any support for the nRF5340.

For more information on the roadmap for this you can contact your Regional Sales Manager (RSM). If you don't know who that is please send me a DM with your location and I'll provide the contact details to you.

Best regards,
Carl Richard
