https://devzone.nordicsemi.com/f/nordic-q-a/36302/nrf52-dk-eddystone-beacon-registration-using-ecdhHi, I&#39;m using the nRF52 dev kit and try to use it as an Eddystone beacon. More precisely I want to use Eddystone EID and I would like to register the beacon using ECDH. So I downloaded the nRF5 SDK v15.0.0 and flashed the Eddystone example.

I can&#39;t even use EID key instead of ECDH.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/140068?ContentTypeID=1Fri, 13 Jul 2018 12:55:42 GMT137ad170-7792-4731-bb38-c0d22fbe4515:22f58e8b-220b-4e82-945a-979ba9951637Roshan Rajaratnam<p>Hi, Thanks for reporting this, I haven&#39;t tested this lately but it should work with either keys unless google has made some api changes. You can also try with the &quot;beacon tools&quot; app to see if registration with ECDH works. I&#39;ll take a look at this and get back to you.</p><div style="clear:both;"></div>
