23 GET Operation Wait State |
|
24 This state issues the Get indication to the Application on entry and then waits for the response. |
|
25 |
|
26 Any OBEX operation will be cause a Protocol Error |
|
27 Chaging the MObexServerNotifyAsync via CObexServer::Start() will cause a Panic |
|
28 A Reset event (Protocol Error, Server Stop, Transport Down) will cancel the notification and move the machine to Disconnected |
|
29 The NotificationComplete event will queue a async one-shot to process the returned object, moving the machine to GetOpSendObject |
