This code is just a small example, error handling is minimal. Now type something in one terminal and press Enter – the string you just typed will appear in other terminal window. After some time ( 30 seconds or less ) both terminals will print “Connected”. To establish connection, type ‘C’, Enter in other terminal. Note that if you send address request before starting the server, address containing all zeroes will be returned. If you are curious, type ‘M’, Enter – the address of the module will be printed.

In one terminal, type ‘S’ and press Enter. In order for two Bluetooth devices to talk to each other, one has to be the server and another one client. Sketch starts by printing short help (see screenshot below) and then waits for the command.

Serial port speed is set to 115200 in the sketch, it can be changed in setup(), if necessary. Also, SPI library shipped with recent versions of Arduino IDE is not compatible with USB Host library, if you have compiler errors related to SPI, replace your library with one from Arduino-0018 or the Playground. You need to compile and load the sketch into both Arduinos and then open two terminal windows, one to a serial port of each Arduino – this can be done from a single computer. To use the program, you need two Arduinos, two USB Host Shields, and two Bluetooth dongles. Standard Arduino library format of the code has not been tested yet, for now it’s easier to just copy all the files in a directory and open btclass_h.pde in Arduino IDE. The source is hosted in GitHub repository. The code has been developed by George Lgotkin. I wanted to have simple communication transport over Bluetooth which would fit into Arduino and the code I’m presenting in this article is doing just that – it’s lightweight terminal program allowing two Arduinos talk to each other over Bluetooth. One good example of such approach is Richard Ibbotson’s HID over Bluetooth implementation – see Wiimote Game Controller Interfacing article for details.

Even though full Bluetooth protocol is heavy and takes a lot of program space, it can be stripped down quite a bit for a particular application. Bluetooth dongles are affordable, interface is well documented, and USB transport layer is very simple. I am pleased to announce addition of Bluetooth dongles to the family of USB devices supported by USB Host Shield. The standard RFCOMM/SPP implementation is available in rev.2.0 of the library.
