Figure 8\u201318. HCI initiating a connection to a device 8.6.3. Canceling Initiating a Connection Sometimes a connection is initiated to a device that is not responding, probably because it is nowhere near the initiating device, and the host wants to cancel this connection request to do something else. In this example, which is shown in Figure 8\u201319, the host uses the LE Create Connection command to attempt to connect to a specific device.<\/p>\n

This also works for initiating a connection to a white list. When the host wants to cancel the initiating of this connection, it sends an LE Create Connection Cancel command to the controller that responds with a Command Complete event for the cancel command as well as an LE Connection Complete event for the initial LE Create Connection command.<\/p>\n

It is important to complete all commands, and the LE Create Connection command is completed with the LE Connection Complete event, regardless of whether the connection was created. Figure 8\u201319. Canceling a connection initiation It should be noted that there is a race condition here. It is possible for the host to send the LE Create Connection Cancel command to the controller at approximately the same time that the controller sends a CONNECT_REQ packet to the peer device but before the LE Connection Complete event is sent to the host to notify it of the new connection.<\/p>\n

In this condition, the LE Create Connection Cancel command will be completed by using the Command Complete event, but the LE Connection Complete event will be sent up to the host reporting the new connection that has been created. It is possible, therefore, to have created a valid connection even when trying to cancel this very same connection.<\/p>\n
