Hi,

I have the same problem with A-LINK BLUEUSB21 dongle. Actually, at one point I was able to scan and see my Nokia phone using hcitool scan but then suddenly it stopped working.

Please find below some hopefully useful output (incl dmesg) from my setup.

Hi,
I have got blue tooth working, but it's tricky. You need to upgrade to the latest sid kernel and add the following setting to cmdline.txt found in /boot

dwc_otg.microframe_schedule=1

You will need a blue tooth dongle with a cambridge silicon chips set - typically nano dongles. Tesco's sell a Tecknika nano dongle that has such a chip set. I installed blueman and bluetooth packages. The blue tooth dongle works much better if you insert it directly into the usb ports. Finally to get blue tooth working well you have to over clock the rpi to at least 800 Mhz. Iv'e got my pi running at 880 Mhz at the moment, but it isn't terribly stable. Here my config file it is best to edit it using another computer. If the pi won't boot or you get errors on booting revise the arm_freq parameter downwards.

Code: Select all

# uncomment if you get no picture on HDMI for a default "safe" mode
#hdmi_safe=1

# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan

# goes off screen, and negative if there is too much border
#overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16

# uncomment to force a console size. By default it will be display's size minus
# overscan.
#framebuffer_width=1280

# uncomment if hdmi display is not detected and composite is being output
#hdmi_force_hotplug=1
