[bluetooth-dev] Chat program



Dear all,
 
          Does anyone wrote a chat program with Openbt???
 
          I cannot successfully write that program, because i cannot no what is the flow of the program.
 
          I use scanf( ) to read keyboard data but it block forever if no data input. Therefore, it cannot read & print the data from serial port .
          Could anyone has the idea??
 
Regards,
Tim
