https://devzone.nordicsemi.com/f/nordic-q-a/39423/use-pca10040-on-a-nrf51-donlge-with-pca10031Hello, I want to use ANT+ communication on the nRF51-dongle that has a PCA10031. I have downloaded the SDK 12.3 to use. I have used some of the BLE examples before that was for PCA10028. To use this examples I used this two threads to manage to runen-USTelligent Community 13Mon, 15 Oct 2018 07:21:00 GMThttps://devzone.nordicsemi.com/thread/152793?ContentTypeID=1Mon, 15 Oct 2018 07:21:00 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8ce5caed-0a95-42b9-94a2-d7bbf53ace99Edvin<p>Hello,</p> <p>The softdevices for the nRF51 series are:</p> <p>S130 - BLE stack.</p> <p>S210 - ANT stack</p> <p>S310 - ANT + BLE stack.</p> <p>So you would need to use an SDK that supports S310.</p> <p>From what I can read in the release notes, the last SDK to support this softdevice is SDK10. I see that this SDK has a PCA10028 folder for the ble_ant_app_hrm example, so you should be able to port this to run on the dongle with the guides from your links.</p> <p>If you want to use a later SDK, you must change to the nRF52 series (nRF52832).</p> <p></p> <p>Best regards,</p> <p>Edvin</p><div style="clear:both;"></div>
