How to use nrf52833 DK as Bluetooth 4 device instead of Bluetooth 5

[HillRipper21]

I would like to test some compatibility features using the nrf52833 DK as a Bluetooth 4 transmitter instead of Bluetooth 5 (which it is by default). I do not see an explicit way of doing this in any of the documentation. According to the documentation, only Softdevice Version S113 is compatible with this particular DK, and the specification for S113 states it is Bluetooth 5.

So my query is should I:

1. Use a different softdevice version that is Bluetooth 4

2.  Keep the S113 softdevice, and avoid using Bluetooth 5 specific features? In this case, is it equivalent to using Bluetooth 4?

Thanks.

Hi

As long as you don't use any Bluetooth 5 features, the S113 SoftDevice should let the nRF52833 act as a Bluetooth 4 device, as these features are mostly optional.

It should be sufficient to just not implement any Bluetooth 5 specific features in the advertising packet.

Best regards,

Simon
