I’ve pulled two bluetooth modules out of some salvaged equipment, and I’d like to interface them with my Arduino Duemilanove 328. They are made by StoneStreet One with gigaAnt antennas. One is a USB bluetooth interface that plugs into the computer, and the other was an embedded board in a Leica GPS that I salvaged. I believe the embedded one is a serial interface, but I’m unsure how to even apply power. I’ve scoured the web for datasheets and other pinout info. I really don’t know where to begin. Both boards have a 6 pin slot with a polarity mark (square pad instead of round) which looks a lot like TTL or FTDI. I don’t know a lot about embedded radios, but I’m willing to go the mile and learn.
The boards can be viewed at: http://flic.kr/p/8pAx8g the one on the left is the USB, the one on the right is the serial. USB’s TTL/FTDI is vertically adjacent to the antenna, the serial is horizontally below the antenna. The board is clearly labeled J1 and the pins one and 6 are labeled.
Has anybody had experience using embedded bluetooth radios? The USB one I can at least apply power and probe around, but I don’t want to fry anything. Anybody come across a good embedded bluetooth tutorial? (This one: http://www.sparkfun.com/commerce/tutorial_info.php?tutorials_id=49 was a good start, but specific to a certain radio.)
According to this PDF by FTDI: http://www.ftdichip.com/Documents/DataSheets/Modules/DS_TTL232R.pdf
The pinouts should be
Does that mean I can solder header into the 6 sockets, apply 5v to pin3, GND to pin1 and connect 4 & 5 to some Digital I/O Pins? What are 2 and 6 for? The pdf called them ‘handshake signal’ pins. I’ve WIKI’d TTL, FTDI, UART and Elementary Physics (for fun) and still come up scratching my head.
Thanks for helping me out… I’m learning a lot, but I still have a long way to be a full fledged hardware hacker. This project would be great for my hacker cred. ;D
