Wow its awesome to finely found someone that did get a wiimote connected to an arduino directly. But could you please share your source and document it. I think it would do the community very good.

And besides that I have an project on my own for wich I want to use the wiimote but I’m just not capable of achieving what you have done.

This can be done. However, I’d rather set it up differently – using regular Arduino connect USB Bluetooth adapter to the host shield and connect your sensor to the serial port of Arduino. Looks like it would be cheaper than Arduino with built-in BT.

This is an exciting platform. I would like to setup something like this:
1.) Arduino with bluetooth modem support to talk to
PC.
2.) This same Arduino to support USB host mode.

My goal is: Gather sensor data on external sensor device with USB interface –> Arduiono USB host mode –> Bluetooth –> PC.

Does this seem possible? The interface to the external sensor device is a simple serial interface.
Does this seem possible?

I did find the datasheet here for the BC41B143A. The common $3 USB Bluetooth Dongles often use these.

Most programming information is in the Bluetooth spec. though for HCI and higher protocols.

L2CAP layer is now working, so Wiimote buttons are working to Arduino over bluetooth. Still got some work to do to clean up disconnect process, only using about 70% of program and data space on AtMega168.

So we have WiiHID, on L2CAP, on ACL, on HCI, on USB, on MAX3421e, on spi! plus lcd and freemem as well.

Hi Yannick, It does look like CSR have tightened their access policy, though I would suggest you talk to them to get access to bluecore 4 data. The CSR chips do comply very well to the bluetooth spec, so that is the base reference. If your device is BC41B143A as is mine, then I can send you datasheet.

I now have HCI layer working reliably on Arduino to Wiimote, and am working on L2CAP layer.

Richard, you say that the CSR chip is well documented but I don’t finf anything on it. Could you help me ?

Showrov, The MAX3420E is a peripheral controller and not a host controller as well. This could be programmed to conect to a PC host, but not to a bluetooth dongle. I have never used the MAX3420 or the MAX3421 in peripheral mode. There are easier and in my opinion better solutions using readily available micros from Microchip, Atmel, Arm and others with already existing software.

Sprawly, The USB port on Deumilanove is also a USB peripheral specific for serial communication, so will not work to a USB dongle. You need the USB host sheild to use a USb dongle. If you just want serial connection, one of the modems is a lot easier.

Hey guys, I just got an Arduino Deumilnove and I wanted to experiment with having it communicate through a usb bluetooth dongle. The arduino has usb connectivity built in so im hoping this could work since the bluetooth modems i saw were upwards of 60 USD where i found a dongle for 15 USD. I;d imagine that it might take some extra code to read but im uncertain of where to start. My arduino has the ATMEGA328 which i know has double the ram capacity of the 168. The dongle that i plan to use is a Ciraga BTA-6130. I chose this one because it has a 100m range. Any help would be appreciated.

Thanks

Hi evreyboy ! I have a Blutooth USB dongle that contains A CSR chip ! Richard, you say that those chip are well documented, but I don’t manage to obtain them from theri website. I would like to register, but all my email adresses did not worked. Could you send them it is possible or tell me the correct way to download them ? Thanks
