NRF5340 audio and DM (distance measurements)

[NCKGTW]

Hi All,

I have to validate following use cases:

• N reflector with nrf52833
• 1 initiator with nrf5340

The nrf5340 will be able to :

1. calculate distance from each reflector (i see that it could be done at application layer even if the DM is peer to peer)
2. sometimes send audio straming message in priority respect to distance measurements

The reflector:

1. will send advertising application data containing sensor data

Is this possible? Which is the distance accuracy in real life scenario in outdoor/indoor applications?

Thanks a lot

Hi Nicola

Note that the nRF52833 won't be able to do anything related to LE Audio, but if it is only to send a notification to the nRF5340 to do something audio related when it is within a specific distance, this absolutely possible based on the information you provided. The Distance measurement library is an experimental feature, so we can't guarantee a specific accuracy, but up to 10 meters at least I think you should be able to expect a 0.5m accuracy mostly. 

Best regards,

Simon

Hi simon, thanks .

Of course the nRF52833 will be replaced by another rf5340 if we will need Audio task on the reflector side.

Thanks a  lot.
