What is possible though, is to measure the distance between the two nRF52 devices you have, then switch to the Thread protocol after measuring the distance and forwarding that information to the OTBR so it has that information. Check out the <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrfxlib/mpsl/README.html#mpsl">MPSL </a>to see how you can provide common services for multiprotocol applications.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
