// - Users of this metrics can deduce Bluetooth device's connection state from these events

// - HCI commands are logged before the command is sent, after receiving command status, and after

//   receiving command complete

// - HCI events are logged when they arrive

//

// Low level log from system/bt

//

// Bluetooth classic commands:

// - CMD_CREATE_CONNECTION

// - CMD_DISCONNECT

// - CMD_CREATE_CONNECTION_CANCEL

// - CMD_ACCEPT_CONNECTION_REQUEST

// - CMD_REJECT_CONNECTION_REQUEST

// - CMD_SETUP_ESCO_CONNECTION

// - CMD_ACCEPT_ESCO_CONNECTION

// - CMD_REJECT_ESCO_CONNECTION

// - CMD_ENH_SETUP_ESCO_CONNECTION

// - CMD_ENH_ACCEPT_ESCO_CONNECTION

//

// Bluetooth low energy commands:

// - CMD_BLE_CREATE_LL_CONN [Only logged on error or when initiator filter policy is 0x00]

// - CMD_BLE_CREATE_CONN_CANCEL [Only logged when there is an error]

// - CMD_BLE_EXTENDED_CREATE_CONNECTION [Only logged on error or when initiator filter policy is 0x00]

// - CMD_BLE_CLEAR_WHITE_LIST

// - CMD_BLE_ADD_WHITE_LIST

// - CMD_BLE_REMOVE_WHITE_LIST

//

// Bluetooth classic events:

// - EVT_CONNECTION_COMP

// - EVT_CONNECTION_REQUEST

// - EVT_DISCONNECTION_COMP

// - EVT_ESCO_CONNECTION_COMP

// - EVT_ESCO_CONNECTION_CHANGED
