https://devzone.nordicsemi.com/f/nordic-q-a/8797/how-to-get-an-image-from-phone-and-display-it-on-epdHii all, I would like to create a project that take an input from any Bluetooth device and display it on display device like EPD. Till now I just hard coded the image and transfer it through SPI to the EPD to display that image. But I now I wanteden-USTelligent Community 13Wed, 19 Aug 2015 11:59:46 GMThttps://devzone.nordicsemi.com/thread/32273?ContentTypeID=1Wed, 19 Aug 2015 11:59:46 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8cd2ad2f-26f4-4f40-8b4f-09bf3b68072eStian R&#248;ed Hafskjold<p>There is no standard way of transferring files using Bluetooth Smart, since it is not designed for large data transfers. However, we have a custom Nordic UART service which can be used to transfer data. We have example code for both the nRF51 side and the phone side. The phone application sends strings of ascii data to the BLE peripheral.</p> <p>You can find the source code of the Android/iOS side application here: <a href="http://www.nordicsemi.com/eng/Products/nRFready-Demo-Apps/nRF-UART-App2">www.nordicsemi.com/.../nRF-UART-App2</a></p> <p>You can then create an app that is based on this UART app, and send the image file as a byte array. It shouldn&#39;t be hard to get this working.</p> <p>The nRF51 side example code is called <em>ble_app_uart</em> and you can find this in the <a href="http://developer.nordicsemi.com/">SDK</a>. It is documented here: <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk51.v9.0.0/ble_sdk_app_nus_eval.html?cp=4_1_0_4_4_17">infocenter.nordicsemi.com/.../ble_sdk_app_nus_eval.html</a></p><div style="clear:both;"></div>
