EWS can build you anything you need. Just tell them what chip you wanna use or what specs you want. They will draw it up in a day or two and produce how ever many you want. The great thing about the Bluegiga iwrap firmware is you have a much easier instruction set for running the BT module and what you want it to do. The BG stuff basically takes a BT modules language and commands and turns it into "BASIC" and you send it by UART or USB. I'd still email em, tell em what your looking for and a number and he can at least tell you about other options, whats on the market, or point you in the right direction.I had a look at the suggested link by maxpower097 and found this:
http://www.goews.com/bluegiga_wt12_module which is $30
but I think I prefer this:
https://www.sparkfun.com/products/10253 which is $15.95 but
But I also think that either one above Must be interface with a DB9 Solder cup male like this: http://goews.com/db9_solder_cup_male
Am I correct? this is for the microcontroller side!
I use to run into that years and years ago.... but with most recent UART technology you don't have to worry about it anymore.... atleast I don't ...Check datasheets for levels required. Because all chips like MAX232 invert the RS232 signal, the PIC RS232 input and outputs are the opposite (also lower voltage) of normal serial signals. Some of these chips may need the signal the right way up.
I am Happy that I don't have to use those 'AT Commands' when I'll use the buetooth...less reading on complicated stuffand the AT command in the BT module usually means run a self test. Otherwise its really not used.
DEV-09873 will be seen as normal serial port on your PC. Given that the driver is installed. The main benefit. Is that you can connect your pic directly to the FTDI chip. No need for any MAX232 circuit. You can also power your PIC from this device. But I am not sure how much current you can draw from it in 3.3 volt mode. Maybe Bmorse know. But I guess up 100mA should be OK.I think I'll go for BMorse suggestion as it looks simpler, however I have a few questions before ordering these FTDI chip
I like your diagrams on post#20
A quick *supid* question! the two suggested method will only use TX, RX and GND. correct? (well I already know this is the case for FTDI IC). And either method will not affect the way the program on PC (chess engine, or whatever...) communicate with the MCU, correct?
Correct, there should not need to be any more connections than that from what I can tell from the datasheet for the BT modules, but you may want to thoroughly read the datasheets yourself and double check your work...A quick *supid* question! the two suggested method will only use TX, RX and GND. correct?

At least with the BlueGiga iwrap firmware it didn't. Yours might I don't know your module and what commands its gonna want.I am Happy that I don't have to use those 'AT Commands' when I'll use the buetooth...less reading on complicated stuff
I plan to use PIC18F26K20, operating voltage: 1.8V - 3.6VDEV-09873 will be seen as normal serial port on your PC. Given that the driver is installed.
