https://devzone.nordicsemi.com/f/nordic-q-a/1185/creating-simple-ble-connection-with-android-to-nrf51822Hello, I am a beginner in the world of bluetooth and bluetooth smart connections. I am working with an nrf51822 Evaluation kit an android phone (Nexus 4 running 4.4.2). I was able to get the heart rate example uploaded to the board and get it workingen-USTelligent Community 13Mon, 30 Dec 2013 11:19:22 GMThttps://devzone.nordicsemi.com/thread/5533?ContentTypeID=1Mon, 30 Dec 2013 11:19:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:600d11e0-7805-4fa6-9e44-62d23fe94d66Marcus<p>I would like to ask the same:</p> <p>And are there any tutorials on how to send commands from android to the board(arduino)? Are there more simple tutorials on how to start writing your own code for the board(arduino)?</p> <p>The perfect tutorial for me would have: First tutorial(creating simple app): scanning after clicking button(everything in one class preferably). Second tutorial(creating simple app): send character after clicking button(everything in one class preferably). Third tutorial: &quot;receive one character&quot; app. Fifth: all above working together.</p> <p>That is most of what the arduino users want from ble.</p> <p>Kind regards.</p><div style="clear:both;"></div>
