I was trying to make a Java program to communicate with the NXT brick, but now Bluetooth seems to fail:
My computer and PDA can "see" the robot via Bluetooth.
Also, nxjbrowse "sees" the NXT, but whenever I click connect, nxjbrowse says "Failed to connect", and in the console it says:
Error from open: Can't connect: Invalid exchange (52)
I'm quiet sure it's not a problem with my computer or BT dongle:
I tried it with several computers. And the result is always the same. And more important: nxjbrowse on the same computer, does work over BT with other NXT bricks.
I flashed the lejos VM to the robot again, but the problem did not disappear (even the files previously uploaded to the brick where still in there, is that normal?)
Thanks in advance,
