hi at all,
how i have to test my BT ?
i send the sketch to my Ard. BT. then i open my emulator and start to try a connection. but i get "Cant connect" exception.
and how i have to do it if i dont use an emulator.must i break the communication between pc and board ?
Generally when you can't connect to the Arduino to upload, it means that you need to change the COM port in the software. Go to Tools > Serial Port, and try another COM port.
If that doesn't fix it then, what was the last thing you uploaded to it?
thnx but i mean that i can upload my sketch to the board.
the problem is that i cant connect to the board in my J2ME phone application over bluetooth.
I used it first in emulator then i tried it with a nokia 3500 and E65.
but i dont think that the problem is the phone type. now i will try a samsung E250 but it will be very helpfull if you or someone else will write some stuff to this topic :-/
