https://devzone.nordicsemi.com/f/nordic-q-a/78584/android-blinky-app-with-passkeyI was able to successfully use the example ble peripheral blinky firmware example with the blinky mobile app. I added peer manager for passkey pairing but the blinky app is not showing a passkey entry screen. It works with the general software NRF connecten-USTelligent Community 13Mon, 16 Aug 2021 14:51:05 GMThttps://devzone.nordicsemi.com/thread/325165?ContentTypeID=1Mon, 16 Aug 2021 14:51:05 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4b3376cb-6efb-42d2-b800-1c5d2263b300dtran11<p>Just discovered that uecc does work. It was a compilation issue.

You could consider other <a href="https://infocenter.nordicsemi.com/topic/struct_nrf52/struct/nrf52.html">chips </a>with larger flash.</p> <p>-Amanda H.&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/324989?ContentTypeID=1Sun, 15 Aug 2021 18:23:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:99ef0b66-5ecd-4ce2-b52e-5839b044e1c3dtran11<p>I think I found the issue with using LESC. It has to do with using micro-ecc instead of oberon. When I switch to oberon it seems to work but it uses more flash.

However I want to use this security option. Does anyone have any ideas on how to get it working? I tried on two Android phones with the same result. Thanks</p><div style="clear:both;"></div>
