Hi
I am using bluetooth device RN-41 and i want to pair my PC with it so i power up the device and search for bluetooth device, i found and it wanted pass key, i wrote 1234(default key) and it wont connect. Can someone pls help me i am using Windows XP and i have installed extern bluetooth usb.
For grins
did you try 0000?
Alrighty
Let’s do this step-by-step.
Now, I saw that you are using a BT dongle on your computer. Before we even get to the RN-41, are you sure that the bluetooth works on the computer side? Were you able to pair anything else with it? Did you try your phone or BT headphones or anything?
I can assume you are using one of those $2, tiny black dongles and well, its a 2-dollar unit… …Might not be the most stable in the world. I would find something else BT and double check the computer side is working.
Next, you say you have a RN-41. This refers to the BT unit itself, not the board. Are you using a stand-alone RN-41 unit or are you using a breakout board like the BlueSmirf from SparkFun? If you are using just the chip, you might be missing some component parts --it will not work just by itself.
Assuming you are using a breakout, you should know you only have one minute to pair. My bluesmirf unit does a “fast blink” when it is in “pair mode”. You gotta be quick.
That’s all I can think of now, let us know how the BT-from-the-computer test goes.
