Hello Pure Data friends,
We are currently trying to make the Bluetooth CUI work with PD.
The Bluetooth Create Usb Interface is the wireless version of the USB CUI, a 13 analog/10 bits and 12 digital I/O interface for sensors. The BTCUI is perfect for embbeded applications like dance, performance, music etc. It's one of the cheapest and smallest wireless interface on the market, and it is Open Hardware !
The USB CUI works all right with PD, with HID tools. We use the [hid] external from PD-Extended 0.39.RC4 (on Mac).
Unfortunately, we didn't succeeded to make the BluetoothCUI working with PD. We have tried [comport] and [hid]. The BTCUI works perfectly on Max/MSP (demo version), as announced by Dan Overholt, its creator. His patch is downloadable at http://www.create.ucsb.edu/~dano/CUI/BlueCUItestRev2.zip and uses the [serial] object of Max/MSP.
The protocol of the CUI is probably similar to the one used by joysticks and such. It consists in a serie of integers with delimiters, the several remaining integers beings the values that the device sends to the computer. See the attached PD patches. Below are out two PD patches. The first one uses [hid] and works with the USB CUI, but not over BlueTooth. (Apple does serial port emulation) The second uses [comport] and almost work. The CUI LED lights up, so it means that it is sending data, but most often, dumping the data from [comport]'s outlet give us nothing.
Would you have any idea of what is missing to imitate, and make even better than the [serial] Max/MSP object ? Otherwise, would it be easier on Linux ?
