https://devzone.nordicsemi.com/f/nordic-q-a/10153/nrf51-notificationsHey All, Just trying to get some advice/examples on how to incorporate notifications into a Custom Service on a nrf51 Dk board using gatts.

Have you set char_md.char_props.notify = 1; when you add the characteristic? Have you added a CCCD? Are you sure the client has written 0x0001 to the CCCD before you send a notification? Does sd_ble_gatts_hvx() return NRF_SUCCESS (0x00000000)?</p><div style="clear:both;"></div>
