https://devzone.nordicsemi.com/f/nordic-q-a/118770/nrf-connect-mobile-doesn-t-bondHi, I&#39;m new to the nRF52840 and BLE and want to send a simple string like &quot;Hello World!&quot; to a paired device (phone) at a cadance of 1Hz e.g. I started with the peripheral sample app (I assumed this would be a good base to start from) and realizeden-USTelligent Community 13Mon, 10 Feb 2025 12:14:13 GMThttps://devzone.nordicsemi.com/thread/522179?ContentTypeID=1Mon, 10 Feb 2025 12:14:13 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3a2d7c82-80c0-4982-886f-add068f93d23Menon<p>Hello,</p> <p>If you are new to nRF and BLE, I recommend exploring the Developer Academy course on<a href="https://academy.nordicsemi.com/courses/nrf-connect-sdk-fundamentals/"> nRF Connect SDK </a>and<a href="https://academy.nordicsemi.com/courses/bluetooth-low-energy-fundamentals/"> Bluetooth Low Energy</a>. This will provide you with a good starting point.</p> <p>Regarding the peripheral sample, I wasn’t quite sure which specific sample you are working with, as there are several peripheral samples available. I recommend looking into the<a href="https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/bluetooth/peripheral_bms/README.html"> Peripheral_BMS sample</a>, which demonstrates bonding.</p> <p>Kind regards,<br />Abhijith</p><div style="clear:both;"></div>
