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

Thanks Carl for your inputs.

As these samples are suggesting to use antenna array along with nrf52833 DK, can you suggest these antenna array can be interfaced with 

development kit.

what are all the compatible antenna arrays available to use with nrf52833?

Thanks,

Hello!

Any AOA antenna array should be compatible per say, but this kit from Insight uses an array similar to the Nordic reference design and should work well. It's also possible to use this solution from uBlox.

We have a partner delivering antenna arrays in the US as well.
