23 OBEX Connecting State |
|
24 This state is entered during an OBEX connection attempt. The authentication state machine is |
|
25 invoked via ParseConnectPacket and PrepareConnect packet. |
|
26 A successful CONNECT will move the machine to Ready. |
|
27 A CONNECT requiring a user password will move the machine to WaitForUserPassword |
|
28 Other CONNECT results may stay in this state or move the machine to TransportConnected |
|
29 A DISCONNECT will be processed |
|
30 An ABORT will cause a Protocol Error |
|
31 Any other OBEX operation will be answered with an OBEX error code |
