https://devzone.nordicsemi.com/f/nordic-q-a/56522/how-can-nrf53832-receive-a-response-from-peer-as-centralHi, all, I try to use NRF52832 as central and peripheral. When it is connected with peer as central, I try to send to peer a message with &quot;sd_ble_gattc_write&quot;, but I can not find a way to receive the response(such as a notification) from peer, canen-USTelligent Community 13Sat, 18 Jan 2020 09:29:39 GMThttps://devzone.nordicsemi.com/thread/229719?ContentTypeID=1Sat, 18 Jan 2020 09:29:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e5310735-c67f-4569-88a1-202479a5077achenwenjing5<p>Thanks for your reply.

If possible, I suggest you implement the <a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v16.0.0/group__ble__bas.html">battery service</a> in the peripheral and central and try to retreive the battery level from the peripheral device (see the ble_app_hrs_c and ble_app_hrs for example). The <a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v16.0.0/structble__bas__c__init__t.html">bas_c_evt_handler </a>function should be helpful.&nbsp; If the only goal is to see that you are able to receive anything from the connected peripheral, this should be pretty straight-forward.&nbsp;</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
