https://devzone.nordicsemi.com/f/nordic-q-a/4700/nrf8001-send-data-to-smartphone-every-secondHello, I&#39;ve connected the nRF8001 module and a light sensor to a microcontroller. Actually I can read data only when I send a string from my smartphone but I want to read data from sensor and send it to my smartphone every second without send anyen-USTelligent Community 13Fri, 05 Dec 2014 11:10:14 GMThttps://devzone.nordicsemi.com/thread/16654?ContentTypeID=1Fri, 05 Dec 2014 11:10:14 GMT137ad170-7792-4731-bb38-c0d22fbe4515:59b4f836-c707-49f5-9ef7-03083a63a9cbDavid Edwin<p>You can look at the <a href="https://github.com/NordicSemiconductor/ble-sdk-arduino/tree/master/libraries/BLE/examples/ble_uart_project_template">UART over BLE example</a> in the nRF8001 SDK for Arduino for more details. This example allows you to send and receive data and you can use this as a template for your requirements.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/16653?ContentTypeID=1Fri, 05 Dec 2014 08:25:05 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e82cf514-746d-47eb-a8fb-6ff4a9e90ea1run_ar<p>Create a tx pipe in nRFgo studio. Use this to send notifications to the phone. Note that the phone will have to enable notifications by writing to the CCCD. Notifications are sent with <em>lib_aci_send_data</em>. make sure you call <em>lib_aci_is_pipe_available</em> first to make sure the pipe is available. In addition it would be a good idea to check that you have available credits (data buffers) using <em>lib_aci_get_nb_available_credits</em>.</p><div style="clear:both;"></div>
