Please have a look at our ble_app_hrs_c in the SDK, we handle the BLE_GAP_EVT_CONN_PARAM_UPDATE_REQUEST event in on_ble_evt() in main.c.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/32800?ContentTypeID=1Thu, 27 Aug 2015 10:32:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a4482698-2363-402e-9e6b-6cb42a96b7a6gigatronik<p>hi hung bui,</p> <p>i got the disconnection reason on my s130(central). I am connected to a nrf8001(peripheral). it seems that the nrf8001 is requesting an update of the connection parameters and my centraldevice does not response. So the connection is lost.. What should i do next?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/32801?ContentTypeID=1Thu, 27 Aug 2015 10:24:42 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b31bb7f0-5654-45e7-bd96-f5df28b7b1dbHung Bui<p>Hi gigatronik,</p> <p>On which device did you get the BLE_HCI_REMOTE_USER_TERMINATED_CONNECTION disconnect reason ?</p> <p>Which device your S130 connect to ? Do you have the same problem when testing with our S130 example ( central and peripheral)</p><div style="clear:both;"></div>
