Hi, 

I am writing a programm using serial profile. But it makes me crzay.

When I am using serial port program (client and server) after I am setting 

using "rfcomm command" ,i.e, listen and connect, it is ok.

But, When I try to merge with my program The Peer doesnot gets Data even though the connection is opened successfully and 

client sent data successfully.

My program is like this.

                                                           open("/dev/rfcomm0") 

     test "config1" -----fork--------------------------^----*----- read( nothing or less than sent!!!) 

                           |                           | signal (to let parent know I can reciev

                           +----     exec ( rfcomm listen) .... 

                                                      | 

                          +------- exec (rfcomm connect) 

                          |                            | signal (to let parent know it can send something) 

     test "config2" -----fork ----                     v ----*------* write( 100 bytes)

                                                          open("/dev/rfcomm4")

 IS THIS Because I am using two USB dongle in the same Desktop linux????

 I think it is not, becuase I tested one dongle with one pc also, and same result.

 Is it bug or something new thing I don't understand??????

 Please check the attachment file for me 

 The reason I do this, we want relaying data (application level scatter net service!!!)

 It is reuired for us but scatter net doesnot supported in my dongle and even bluez!!

 thanks!!!!!
