Hi, I also got the Error sending data! once today. I loeokd around the and found this:* * Right now errors message are simply forwarded to the GUI. The reason for that is they would otherwise be unnoticed and the user has no idea what’s going on. I cannot really do anything against these errors since they come from libraries that I just use. I can only change my program to behave more nicely when they occur. Instead of displaying a blocking error message there could be an Error Log Window or something like that. In case of severe errors the program could gracefully reset itself to initial state or do a reconnect (I have to investigate into that). Other suggestions?More info: the previous release did not have this problem. Also, when run with BlueCove debug enabled, nothing appears abnormal.I guess that’s because all errors were simply ignored This happens consistently 60 seconds after the wiimote connects. Does the code do a status check on the wiimote then?Yes, I do a status check every minute to update the battery level. Does the program work normally until the error occurs?Uwe
