Is it sending out indications to other central devices? Maybe you can do a sniffer trace of a connection that works and compare it with a sniffer trace of connection with the nRF52840 central?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/83769?ContentTypeID=1Wed, 19 Apr 2017 12:39:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d60b518e-b2c9-4508-bdf7-2446ff12d75evinu<p>in my (sd_ble_gattc_write) function it is showing successfully written but in periphreral side iam not getting any indication ..plzz help me sir iam trying from 4 days.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/83767?ContentTypeID=1Wed, 19 Apr 2017 11:59:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:932a4d87-00e0-4abc-8ff5-b1bc966422f0Petter Myhre<p>So everything is ok?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/83763?ContentTypeID=1Wed, 19 Apr 2017 04:54:15 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b80ec823-faac-4053-9f65-ca59ddd1e340vinu<p>actually i made nordic as a central and it is GATT client and my peripheral is GATT server which is sending temperature data by using health temperature service .and iam able to send indications successfully to the server</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/83770?ContentTypeID=1Tue, 18 Apr 2017 15:57:30 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6ba906cc-926d-4ff7-a151-ebc94eb8cc2aPetter Myhre<p>So you have enabled indications by writing to the CCCD?
