lsmod and dmesg both produce no bluetooth output
Any suggestions?
Here the same. Bluetooth isn`t working under Armbian and Debian. Any solution?
Hi
for Armbian,you can run start_bt.sh
root@rockpi4b:/usr/local/bin# ./start_bt.sh
and you will see that
We must stop getty now, You must physically disconnect your USB-UART-Adapter!
Using /dev/ttyS0 for Bluetooth

Thank you very much, that helps instantly after a manuell search for adapter on the GUI.
But how can I integrate this in the start prozess? Sorry for that (maybe) stupid question, but I´m a Linux Dummie.
You can edit /etc/rc.local file
Add line
/usr/local/bin/start_bt.sh &
Before the exit 0 line.
It will run every time booting.
That script does not exits on my system:

And naturally BT is not working. Image written to emmc is rockpi4b-ubuntu-bionic-minimal-20190104_2101-gpt. How to proceed to get this working?
Really? Ofc it doesn’t exist on your system, because your system is not Armbian, so try it with armbian first
Oooops 
I’ll try with correct image
Yes…BT works with Armbian and board is able to see my RuuviTag’s 
Added to root’s cron entry: @reboot /usr/local/bin/start_bt.sh >/dev/null 2>&1
Now BT is available after reboot w/o manually activating it.

Faced the same issue. Switched from Armbian to Ubuntu since I did not get iptables there.
But with this ubuntu, no bluetooth:

I have troubleshooted and tested with different images and after i finally got iptables working I’d like to stick with ubuntu. But if BT does not start to work I need to continue finding working image with iptables and bt…
Hi, Miha
To enable BT on Ubuntu Server, you should install the following package:
apt-get install bluez ap6256-firmware
First stop the rfkill
echo 1 > /sys/class/rfkill/rfkill0/state
Download the BT firmware with brcm_patchram_plus1 tool
brcm_patchram_plus1 -d --enable_hci --no2bytes\
--use_baudrate_for_downloade --tosleep 200000 \
--baudrate 1500000 --patchram \
/system/etc/firmware/BCM4345C5.hcd /dev/ttyS0 \
> /dev/null 2>&1 &
It will run on the background.
Now check the hci device
hciconfig
hci0: Type: Primary Bus: UART

TX bytes:2284 acl:0 sco:0 commands:49 errors:0
Scan other BT devices
hcitool scan
You can add the first two lines on /etc/rc.local to download BT firmware every time.
Did following:
root@rockpi:~# apt-get install bluez ap6256-firmware

Works! Thank you Jack
Hi guys,
I am a newbie in Linux.
I managed to get Bluetooth connection for my Bluetooth 3.0 keyboard with built in keypad when disable the wifi connection.
Can’t make both BT and WIFI working together…
Any advice?
Don
Hi guys,
