Arduino and Bluesmirf? Answered

HI,

I have an arduino uno and I am trying to use a BlueSmirf to light up an LED. The problem I am having is that whenever I plug in the Bluesmirf, I cannot update the script on the arduino.  When I do, I recieve this error message :avrdude: stk500_getsync(): not in sync: resp=0x00. I have been able to connect the Bluesmirf to my computer, but I have not been able to get it to reply or to recieve data.

Best Wishes
Amantux

Im having a very big problem. At first, i could successfully pair the bluesmirf silver bluetooth modem with the laptop. But after that, when I deleted the modem from the laptop's devices, I could not install it back. It will say that there are no drivers installed for the bluetooth peripheral device and there will be no COM port for the device, meaning I can't use the terminal software 'Coolterm' to configure the device. I am using a windows 7 professional laptop

The blueSmirf is a rovingnetworks RN41 or 42 module. If I were you, I'd try tying pin 16 (CTS) of the RN41/2 to the 3.3V supply rail WHILE you are trying to download a sketch.

I used to get that error when the Arduino drivers weren't installed correctly. Can you upload any other sketches?

What OS are you using? If Windows, go to devices and see if your Arduino's listed under USB devices or unknown. If unknown, it's not installed properly.

I am using the 1.0 release of the arduino devolopment environment with an arduino uno. If I remove the Bluesmirf, I can upload sketches to the board, however, once the bluesmirf is connected I cannot
Hope that helps

That's probably because the bluesmirf is using some of the same lines that the Arduino bootloader uses.

If you HAVE to have the 'smirf connected, find someway to "tristate" its serial lines when you want to upload a sketch.
