Where I can download nrf51822&#39;s programhttps://devzone.nordicsemi.com/f/nordic-q-a/19712/where-i-can-download-nrf51822-s-programI had downloading many versions SDK,from 10.0.0 to 12.2.0.But when I Program SoftDevice then download the examples,such as the path: nRF5_SDK_12.0.0_12f24da\examples\ble_central_and_peripheral\experimental\ble_app_hrs_rscs_relay\pca10028\s130\arm5_no_packsen-USTelligent Community 13Wed, 15 Feb 2017 08:51:12 GMTRE: Where I can download nrf51822's programhttps://devzone.nordicsemi.com/thread/76699?ContentTypeID=1Wed, 15 Feb 2017 08:51:12 GMT137ad170-7792-4731-bb38-c0d22fbe4515:89c57641-2fba-4814-b315-8d8efab033a7J&#248;rgen Holmefjord<p>Hi,</p> <p>You need to program the softdevice before you can get Bluetooth applications to work. See the section <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v12.2.0/getting_started_softdevice.html?cp=4_0_1_1_3"><em>Running examples that use a SoftDevice</em></a> in the getting started chapter of the SDK documentation.</p> <p>You can run code that is written for nRF51422 on your nRF51822. These devices are equal, execpt from 51422 supporting ANT protocol in addition to BLE.</p> <p>Best regards,</p> <p>Jørgen</p><div style="clear:both;"></div>
