I have not tested it personally, but it is implemented in ble_advertising.c (same file that has ble_advertising_init()).</p> <p>According to the declaration in ble_advertising.h: &quot;This function can be called if you wish to reconfigure the advertising data The update<br /> * will be effective even if advertising has already been started.&quot;</p> <p></p> <p>Best regards,</p> <p>Edvin</p><div style="clear:both;"></div>
