https://devzone.nordicsemi.com/f/nordic-q-a/4028/early-nrf51822-ek-pca10001-v2-0-0-and-new-sdk-sHi all, some time ago we bought a nRF51822 Evaluation Kit with the PCA10001 being Version v2.0.0. Why exactly is it not recommended to work with the new SDKs such as SDK6? I downloaded the ble_lbs_example from nAN-36 from the Github, compiled iten-USTelligent Community 13Thu, 09 Oct 2014 11:35:25 GMThttps://devzone.nordicsemi.com/thread/14446?ContentTypeID=1Thu, 09 Oct 2014 11:35:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2cf9a0c1-9b4e-4f19-8821-0ba62b5e5afbAsbj&#248;rn<p>The code examples from SDK 6.x.x is design to work with Softdevice 7.0.0 as this softdevice is slightly bigger than the previous versions. So the memory settings would be wrong for the Softdevice 5.x.x and 6.x.x. I assume that you have checked the programming with the blinky example and that the blinky example run as expected? It may sound redundant, but it would at least rule out any issues with the programming itself. Does the kit show up in nRFgo studio? Do you see the intended softdevice in the memory area in nRFgo studio? Have you tried any of the other SDK 6.x.x examples along with SD110 version 7.0.0?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/14445?ContentTypeID=1Wed, 08 Oct 2014 17:07:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d16eab94-5c15-4588-8f33-2f7dcb73a589Stephan<p>Hi, yes, I tried all of them: SD110 v5, v6 and v7</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/14444?ContentTypeID=1Wed, 08 Oct 2014 17:04:30 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d45b1923-b1c7-49a5-9c52-3fba39edd188John<p>Are you certain that the soft device is programmed on your nrf51822?</p><div style="clear:both;"></div>
