https://devzone.nordicsemi.com/f/nordic-q-a/11321/the-proper-function-to-call-to-pull-the-received-data-from-s120-softdevice-stackI have been working on the multilink example lately (version: 8.0), I have identified the function to send data on the peripheral part, it is sd_ble_gatts_hvx(), but I&#39;m having a real hard time locating the function to receive data from the s120 softdeviceen-USTelligent Community 13Thu, 14 Jan 2016 13:43:12 GMThttps://devzone.nordicsemi.com/thread/42583?ContentTypeID=1Thu, 14 Jan 2016 13:43:12 GMT137ad170-7792-4731-bb38-c0d22fbe4515:93c85099-cf83-43e9-b2e0-6415652af8a3Petter Myhre<p>I think you should have a look at the BLE central tutorial, found <a href="https://devzone.nordicsemi.com/tutorials/">here</a>.</p> <p>Whenever the SoftDevice receives a notification, sent with sd_ble_gatts_hvx() from the server (here the peripheral), it will send a BLE_GATTC_EVT_HVX event to the application. With the event you will get a ble_gattc_evt_hvx_t struct, and in this you can find the data.</p> <p>In the ble_app_multilink_central example you can see that this is handled in client_handling_ble_evt_handler() in the BLE_GATTC_EVT_HVX case. This is turn calls on_evt_hvx() where the data is used to toggle the LEDs.</p><div style="clear:both;"></div>
