I have been working on a program that uses AsyncStreamsObject to send a file. It was working flawlessly but now all of a sudden a get an error every time I try to connect. Basically, my program creates a server/client Bluetooth connection and then the server will immediately attempt to send a file to the client. As soon as the devices successfully connect, I get the following errors:
From the server:
astream_Error: java.io.IOException: Software caused connection abort
From the client:
astream_Error: java.lang.Exception: CRC value does not match
The server error seems to be the standard error that gets thrown any time a BT connected device terminates the connection, so that is probably a red herring. I've been trying to investigate the client error that gets thrown regarding CRC validation.
As I said, up until this evening, this was working flawlessly. However, now, this error occurs every time I attempt to use one particular device as a host. The code I'm using is fairly simple:
Everything else should be handled by the AsyncStreamsObject class. I have not made any changes to that file other than added a few additional lines for debugging purposes. I never get into Sub astream_NewData at all, the error gets called first.
I'm not even sure where to continue troubleshooting efforts, since everything is really contained within subroutines that I did not write, and have no insight into how to troubleshoot.
I appreciate any help you can provide. Let me know if I need to provide any additional information.
