Enable Bluetooth on Cubietruck

[kdeenkhoorn]

Cubieplayer, Please add the module hci_uart to your kernel because it is needed for Bluetooth to run.

The following is tested: If the module is there add it with some others to /etc/module:

    # Bluetooth
    rfcomm
    bnep
    hci_uart
    bluetooth
    hidp

Then restart the cubietruck.

    shutdown -r now

Then do:

    apt-get install bluez

Then download from https://code.google.com/p/broadcom-bluetooth/ the sources of 'brcm_patchram_plus.c' and change the code and remove the wait loop:

    if (enable_hci) {
            proc_enable_hci();

            while (1) {
                    sleep(UINT_MAX);
            }
    }

so whats left will be:

    if (enable_hci) {
           proc_enable_hci();
    }

Don't know why the wait is there but i have asked a question at google code about it. Now you can wait for the answer on my question what's the impact of this hack or compile the program using make like i did. If you are missing some bluetooth libraries during compile do 'apt-get install libbluetooth3 libbluetooth-dev' in advance.

Then after compilation execute the following commands once after every reboot as root in this order:

    echo -n "" > /dev/ttyS1

This initial echo has to be done to open the ttyS1 line, else the first run of brcm_patchram_plus will fail.

    ./brcm_patchram_plus -d  --patchram /lib/firmware/ap6210/bcm20710a1.hcd --enable_hci --bd_addr 11:22:33:44:55:66 --no2bytes --tosleep 1000 /dev/ttyS1
    hciattach /dev/ttyS1 any
    hcitool dev
    hciconfig -a
    hcitool scan

And now you're good to go.

Also look at: http://linux-sunxi.org/Cubietruck/Bluetooth and: http://archlinuxarm.org/forum/viewtopic.php?t=7253&p=39808#p39885

Probably the scripting mentioned in the last archlinuxarm.org link will work for cubian also but i have not tested that yet ... time is up for tonight. ;-)

Finally worked out a working script for enabling Bluetooth at boot time on the cubietruck. Sources and installation instructions can be found at: https://github.com/kdeenkhoorn/cubietruck-scripts/tree/master/bluetooth

Thank you for sharing, I'ved added to my TODO list, act ASAP.

Any eta when this will be available?

Hello, http://linux-sunxi.org/Cubietruck/AP6210 Did someone tried already to implement this drivers in the kernel for Cubian? Iam not good enough in Linux to compile a KERNEL with patches yet. Would be a great help to get a ready patched 3.4.79 suni7 or a tutorial for newbies with a HOWTO. :-) Rds Joe
