https://devzone.nordicsemi.com/f/nordic-q-a/119297/enabling-notification-in-central-applicationI&#39;m writing a client/central application connecting to a peripheral, discovering a service, and then wishing to enable notifications from a specific characteristic. Once enabled, I expect to receive the BLE_GATTC_EVT_HVX events and go from there. en-USTelligent Community 13Tue, 25 Feb 2025 16:24:26 GMThttps://devzone.nordicsemi.com/thread/524671?ContentTypeID=1Tue, 25 Feb 2025 16:24:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:24cbb793-a8e8-4a6d-85a9-cdca2a649a08Vidar Berg<p>Hello,</p> <p>I suggest using the&nbsp;ble_nus_c_tx_notif_enable() function in the ble_app_uart_c example as a reference. This implementation uses the&nbsp;<a href="https://docs.nordicsemi.com/bundle/sdk_nrf5_v17.1.0/page/lib_ble_gatt_queue.html">BLE GATT Queue</a>&nbsp; module to queue the write request, because issuing the request directly may lead to a &quot;busy&quot; error if another request is already in progress.</p> <p>Best regards,</p> <p>Vidar</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/524468?ContentTypeID=1Tue, 25 Feb 2025 02:47:17 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9974cd73-047e-4b49-87a1-2b9addafac4dJchristf<p>PS: I&#39;m using SD 140</p><div style="clear:both;"></div>
