This is a bt adapter that is used on some reprap with bt connection. Also will provide detailed instructions on how to setup with using android device only.

Bluetooth is a wireless technology used for short range communications. Bluetooth has protocols that allow it to mimic serial communications and this makes it perfect for use with arduino, and on a ramps board for 3d printing software controls such as pronterface, and repetier host.

Also it allows programing to be done on any device that has arduino ide. this includes PC, Mac, ubuntu, and android.

here is a video of it working on a reprap.

here is a program i made that runs on arduino ide and automatically detects baud rate and sets up device. bt_magic.ino for arduino runs on version 1 of arduino ide. also serial monitor needs to be at 57600 and set to no line ending. cr and line need to be disabled for serial monitor.

here is a video of the program used to setup bluetooth adapter link title

SETUP with android devices requires a ON THE GO CABLE and the following free apps to be installed Arduino Communicator (to setup usb comm), arduino droid, and free usb serial. free usb serial app acts as the terminal because the system monitor does not yet exist in android version of arduino ide.

I will do another video soon (using a better camera), and add multicomm port program ability.

enjoy!. questions or comments or feedback contact me on the forum. thanks!
