https://devzone.nordicsemi.com/f/nordic-q-a/20595/nrf51822-scan-android-phone-or-bt-speakersHey! I am working on NRF51822-QFAC, with the help of SDK 12.2 with the aim of scanning my bluetooth speakers and mobile phone. For the same, I have loaded the project \examples\ble_central\ble_app_uart_c\pca10028 on the MCU (after loading the Softdeviceen-USTelligent Community 13Sat, 18 Mar 2017 14:43:47 GMThttps://devzone.nordicsemi.com/thread/80263?ContentTypeID=1Sat, 18 Mar 2017 14:43:47 GMT137ad170-7792-4731-bb38-c0d22fbe4515:61c81ccd-6a93-48c6-91b9-b9224cdc50casrijan12<p>Hello Jan! This is crisp. Your answer coupled with <a href="https://devzone.nordicsemi.com/question/80642/central-scanner-and-mobile-device/">this one</a> gives me complete clarity on the matter. I used the NRF Connectivity Android App to simulate the phone as Beacon, and it gets detected now.</p> <p>Thank you :)</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/80262?ContentTypeID=1Sat, 18 Mar 2017 14:10:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:93c64233-219a-4aee-a364-d1801021c119endnode<p>Hey srijan,</p> <p>Just a quick sanity check: are you sure that your Xiaomi phone and speakers are advertising? Phones normally don&#39;t send BLE advertisement packets unless there is some application which asks for it and as there is not HD sound transport standard for BLE most of the equipment like BT speakers or headphones or handsfree are using BT Classic A2DP profile/protocol which has nothing to do with BLE (BT LE if you want;).</p> <p>Cheers Jan</p><div style="clear:both;"></div>
