https://devzone.nordicsemi.com/f/nordic-q-a/5794/reading-data-from-tmp102-and-nrf51822-ekI am a very beginner on embedded field. I have a nrf51822 and tmp 102. I follow this direction on mbed site link text and it&#39;s actually working. The code provide is C++, simple and easy to understand. The only problem for that code is it&#39;s inen-USTelligent Community 13Tue, 03 Mar 2015 15:11:24 GMThttps://devzone.nordicsemi.com/thread/20264?ContentTypeID=1Tue, 03 Mar 2015 15:11:24 GMT137ad170-7792-4731-bb38-c0d22fbe4515:cb025030-9d03-4e7a-9ca4-99c4f4025cf2Stefan Birnir Sverrisson<p>Hi</p> <p>It seems that all these sensors are using TWI (I2C) interface for communication. There is a <a href="https://devzone.nordicsemi.com/documentation/nrf51/6.1.0/s110/html/a00051.html">TWI example in the nRF51 SDK</a> which you can use to receive the data from the sensors. It should be fairly easy to send this data over BLE in order to receive with a smartphone. We have several BLE (LE) examples in the SDK as well that you can use in combination with the TWI example to send the data over BLE to be received by a smartphone, IOS or Android.</p> <p>There is a blog <a href="https://devzone.nordicsemi.com/blogs/11/using-nrf51-sdk-with-the-nrf51822-mbed-kit/">here</a> that instructs how to enabled the mbed kit for C code and Keil. The streamlined method is however to purchase the latest <a href="https://www.nordicsemi.com/eng/Products/nRF51-DK">nRF51 DK development kit</a> to start development with examples in the nRF51 SDK.</p> <p>Here is <a href="http://developer.nordicsemi.com/nRF51_SDK/doc/7.2.0/s110/html/a00008.html">instruction</a> on how to operate the TWI drivers available in the SDK.</p><div style="clear:both;"></div>
