Arduino weird bluetooth module Recently I bought a BT module from eBay which was very cheap. I didn't really noticed the image and I just bought it. When it came I couldn't find any holes to solder the headers. Also the specific module is pretty rare and I couldn't find anything.

Here is an image:



How do I wire up this chip?
From the picture you posted, i was able to google and find something called a BC04-B Bluetooth serial module. It looks almost exactly like yours, and I found a diagram on how to hook it up.


I also believe that these are the serial commands you can use with it...
