nRF52832 advertising not picked up by certain Androidshttps://devzone.nordicsemi.com/f/nordic-q-a/80380/nrf52832-advertising-not-picked-up-by-certain-androidsWorks on Huawei P20 Lite (Android v9), Samsung J3 (Android v7.1.1), all IOS phones. Doesn&#39;t work on Samsung A50. Samsung A50 does see the devkit when using the same firmware., could this be hardware related?

You should use the radio_test in the nRF5 SDK to setup a carrier, then measure the frequency accuracy of the carrier on a spectrum analyzer, the center frequency should be for instance within +-96kHz.</p> <p>Kenneth</p><div style="clear:both;"></div>RE: nRF52832 advertising not picked up by certain Androidshttps://devzone.nordicsemi.com/thread/332910?ContentTypeID=1Wed, 06 Oct 2021 23:03:21 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2089f71b-3d4d-4721-ae20-c880518f9b79danimalia<p>note - verified on two separate A50s. Have also rebooted in safe mode, and removed all BLE apps. phone still does not detect this nRF.&nbsp;</p><div style="clear:both;"></div>
