https://devzone.nordicsemi.com/f/nordic-q-a/65006/scan-requestSir, How can i use the SCAN REQUEST to transmit dynamic data PDU to the PERIPHERALS ? The idea is that the CENTRAL sends data to PERIPHERAL without make a connection! Is that possible ? And how the PERIPHERAL can read this PDU ?

Following the BLE specification you need to be in a connection between a central an a peripheral in order to send data between them two.</p> <p>If you want to advertise additional data over a BLE beacon you should take a look at the BLE beacon example in the SDK. More about advertising can you find in this <a href="https://devzone.nordicsemi.com/nordic/short-range-guides/b/bluetooth-low-energy/posts/ble-advertising-a-beginners-tutorial">Bluetooth Low Energy Advertising tutorial</a>, and using scan response data to extend your advertising packet is also further discussed/explained in <a href="https://devzone.nordicsemi.com/f/nordic-q-a/36365/scan-response-data-to-be-added-to-sdk-ble_app_beacon-example">this case.</a></p> <p>Best regards,</p> <p>Marjeris</p><div style="clear:both;"></div>
