Regarding the touch sensor I see that you already have a discussion about that going on <a href="https://devzone.nordicsemi.com/question/123072/nrf51822-with-gpio-programming/">here</a>, so I suggest you continue with that there.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/81504?ContentTypeID=1Thu, 30 Mar 2017 04:59:55 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1d6e0d11-7b98-44f7-8e74-c9845fccae77KETAN_PATEL<p>Thanks for reply @Martin Bors-Lind..</p> <p>try to connect touch sensor with NRF51822 and it&#39;s gives output in form of 0 &amp; 1 only. i want to send that data through NRF51822 to another NRF51822.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/81503?ContentTypeID=1Tue, 28 Mar 2017 11:07:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:372797c0-4b55-4e42-9215-7b2d5466259dMartinBL<p>Hi,</p> <p>That is simply verison 1 of our S130 Bluetooth LE Stack. You can use that to make BLE applications with your nRF51. There is also a version 2 though, and I suggest that you use that to get the latest features and upgrades.</p> <p>Have a look at the <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf51/dita/nrf51/compatibility_matrix/nRF51422_nRF51822_ic_rev_sdk_sd_comp_matrix.html?cp=3_0_4">Compatibility Matrix</a> to see what SDKs you can use with the Softdevices and the <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.softdevices51/dita/softdevices/s130/s130.html?cp=3_7_2">S130 Softdevice Specification</a> to read more about what it actually is.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/81502?ContentTypeID=1Tue, 28 Mar 2017 11:03:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f0ba4d56-4f7f-4a8a-b577-ed4dd25afd4aendnode<p>Sorry but hard to answer. Can you elaborate about what use case are you solving, what HW/SW you have on both sides?</p><div style="clear:both;"></div>
