Wiimote for NMT
I have been trying to see if I can see my Wiimote on the NMT/PCH C200 media player that I have. So far it does seem to work, but the bluetoothd process tend to hang in bad ways.
For now, install the CSI package, or the ZIP file. My little init script will assume the path is /share/Apps/wiimote/ that we are working in, but the only path required is for LD_LIBRARY_PATH.
Inside the package, you will find "init.sh" file. This has the setup procedure, and what is expected. I tend to cut'n'paste the lines, rather than to try to run it.
For example, after a reboot do:
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/share/Apps/wiimote export LD_LIBRARY_PATH cat /proc/dmesg & mkdir -p /var/run/dbus/ /share/Apps/utils/bin/rsync --inplace -ar etc/ /etc/ ./dbus-daemon --system insmod bluetooth.ko insmod l2cap.ko insmod hci_usb.ko
This sets up the PATH to find libraries in the wiimote directory. I cat the kernel messages here so that we can more directly see the output from kernel modules. It is initially very verbose, but don't worry about that. It is only new lines that are interesting.
Then we copy over the dbus files to etc. This assumes you have rsync installed, which is part of C200 utils. (Thank you vaidyasr) Then we start dbus daemon. Finally we load all the kernel modules.
I see the following output.
Bluetooth: Core ver 2.11 NET: Registered protocol family 31 Bluetooth: HCI device and connection manager initialized Bluetooth: HCI socket layer initialized Bluetooth: L2CAP ver 2.8 Bluetooth: L2CAP socket layer initialized Bluetooth: HCI USB driver ver 2.9 usbcore: registered new interface driver hci_usb
Here is were it sometimes goes wrong. We start the bluetoothd process, which finds the hardware, and enables any. This process tends to hang for me. I ignore it, and everything works, but it is rather annoying.
For me, if is run ps now, it will print everything, until it gets to the bluetoothd process, then hangs. Oh well
Now, for me, I can list my bluetooth device.

Nice. I can look for the wiimote:
./lswm_c200 Put Wiimotes in discoverable mode now (press 1+2)... 00:17:AB:31:9A:03
And perhaps, more fun:
and use 1, 2, 3 and so on, to turn the Wiimote LEDs on and off.
Please let me know if it works for you, and if not, what part fails. Either use the NMT forum thread, or just send me an email.
