9 years ago Hey there, starting bluetooth is working fine and searching for devices, too.
But if I pair my Logitech Bluetooth Audio Adapter with the CT, the whole system freezes. What can I look for, to find the problem ?
Bellow step I try more than 3 time and confirm working for Cubian X1 Desktop. FOR CUBIETRUCK ONLY!
1.)Upgrade the kernel to latest version with hci_uart support.
sudo apt-get update sudo apt-get upgrade linux-image-3.4.79-sun7i **Make sure is linux-image-3.4.79-sun7i 3.4.79-4cubian or above.
2.)Install requirement app.
sudo apt-get install libbluetooth3 libbluetooth-dev sudo apt-get install bluez blueman sudo apt-get install git-core
3.)Adding the related modules to /etc/modules.
bluetooth
rfcomm bnep hci_uart bluetooth hidp
4)Reboot with totally power off. let's the kernel and added modules working.
sudo shutdown -h now \ remove the power source for 10 second and reconnect power!
5.)Check your kernel & modules status
sudo uname -a
You should see this: Linux Cubian 3.4.79-sun7i #19 SMP PREEMPT Fri Oct 10 03:20:03 CST 2014 armv7l GNU/Linux
sudo lsmod
you must see this, to make sure the module are loaded:
Module Size Used by hidp 17640 0 hci_uart 24892 1 bnep 14422 2 rfcomm 58826 14 bluetooth 265030 25 bnep,hidp,hci_uart,rfcomm
6.)Download the bluetooth script (brcm_patchram_plus and brcm40183-patch).
cd /home/cubie git clone https://github.com/kdeenkhoorn/cubietruck-scripts.git ./bt cp /home/cubie/bt/bluetooth/usr/local/bin/brcm_patchram_plus /usr/local/bin chmod 755 /usr/local/bin/brcm_patchram_plus cp /home/cubie/bt/bluetooth/etc/init.d/brcm40183-patch /etc/init.d chmod 755 /etc/init.d/brcm40183-patch cp /home/cubie/bt/bluetooth/etc/default/brcm40183 /etc/default chmod 755 /etc/default/brcm40183 update-rc.d -f brcm40183-patch defaults
7.)reboot
8.)Verify your bluetooth status & troubleshooting!!
sudo hcitool dev
**make sure you see "hci0 xx:xx:xx:xx:xx:xx" like bellow.
Devices: hci0 43:29:B1:55:01:01
DNS issue and kernel issue can cause the brcm_patchram_plus and brcm40183-patch not work!
9.) /etc/init.d/brcm40183-patch start
[ ok ] brcm40183 device allready initialized...done. Devices: hci0 43:29:B1:55:01:01
This two command will let's u know the bluetooth working or fail.
sudo hcitool dev /etc/init.d/brcm40183-patch start
Try your bluetooth Manager (blueman) Menu > system > preferences > Bluetooth Manager
**If your bluetooth working, you must able to click the search button!
