National Semiconductor's LMX9838 Bluetooth IC

Here is one of my old projects:

I was able to acquire free 5 pcs sample of LMX9838 IC. I was able to use and evaluate it quickly. Here is my exact schematic (I created this in Eagle).

I was able to use this to control my microcontroller projects (LMX9838 in transparent mode) via
1. my Nokia E63 with a PythonS60 script.
2. USB Bluetooth using C# SerialPort Class
