Distance measurement on nrf52 series

[haricane]

Hello Nordic Semi team, 

I have some nrf52810 and nrf52832 devices already in production. 

I would like to add distance measurement between nrf52810 and nrf52832. Is this possible? I see the documentation say only nrf52833, 840 is supported. 

Kind regards, 

Hari

Hi Hari

The smallest device supported for the Nordic Distance Toolbox (distance measurement library) is the nRF52832. The nRF52810 simply doesn't have enough RAM and Flash memory to make use of it. They're also missing the floating point HW support so they can't run the algorithms needed efficiently. As of now we've only added support for nRF52833, nRF52840 and nRF5340, but nRF52832 should be possible with some code optimization or by setting it to only be the initiator or only reflector. See the Distance measurement library for more information.

Best regards,

Simon

HI Simon, 

Thanks for the clarification. I had suspected the hardware floats might be needed.
