Reconnect after sd_ble_gap_disconnect

Question

Hi 
 I am using the nRF52832DK and the BLE_App_Blinky. 
 I have a stable BLE connection to a phone and then I try to close the connection inside the nRF with sd_ble_gap_disconnect(m_conn_handle, BLE_HCI_REMOTE_USER_TERMINATED_CONNECTION);. 
 It do a disconnect, but right after it reconnects again by firing BLE_GAP_EVT_PHY_UPDATE_REQUEST. 
 Why is this event generated? Do I have some settings that makes it reconnect or should I use another parameter instead of BLE_HCI_REMOTE_USER_TERMINATED_CONNECTION? 
 
 Regards, 
 Morten

Hi Morten, In that case you would need to handle the re-advertising on your own. What you need to do is to set a flag when the nRF52 actively disconnect the connection. In that case you don't re-advertise (start advertising after disconnected). If the flag is not set, then you can start advertise in the BLE_GAP_EVT_DISCONNECTED event. 
 To be able to handle the task manually you need to disable ble_adv_on_disconnect_disabled.
