If you want to send the button state over BLE, we have a specific service for this, <a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/group__ble__lbs.html">LED Button Service Server</a>. You can test it out using the <a title="BLE Blinky Application" href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/ble_sdk_app_blinky.html?cp=7_1_4_2_2_3">BLE Blinky Application</a>.</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>
