    Re: MIDlet crashes using BTSPP. Is it a bug?

    OK Robert, thank you for your reply, but I have some doubts yet:

    What is the baud rate that you use? What is the amount of data that you transfer? What is your symbian phone?

    Best Regards,

    I had a similar problem, and this happened because I had a call to "cancelInquiry()" method in "inquiryCompleted()" method. Perhaps this is your problem.
