No bluetooth adapter found

lsmod and dmesg both produce no bluetooth output

Any suggestions?

Here the same. Bluetooth isn`t working under Armbian and Debian. Any solution?

brian · December 17, 2018, 2:51am

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!

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.

jack · December 18, 2018, 3:53am

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?

Dante4 · March 2, 2019, 10:31am

Really? Ofc it doesn’t exist on your system, because your system is not Armbian, so try it with armbian first

miha · March 2, 2019, 12:40pm

Oooops I’ll try with correct image

miha · March 2, 2019, 2:06pm

Yes…BT works with Armbian and board is able to see my RuuviTag’s

miha · March 3, 2019, 8:19am

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:

Installed bluetooth and it’s running:

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
	BD Address: 43:45:C5:00:1F:AC  ACL MTU: 1021:8  SCO MTU: 64:1
	UP RUNNING
	RX bytes:785 acl:0 sco:0 events:49 errors:0
	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.

miha · March 16, 2019, 12:31pm

Did following:
root@rockpi:~# apt-get install bluez ap6256-firmware Reading package lists… Done Building dependency tree Reading state information… Done bluez is already the newest version (5.48-0ubuntu3.1). ap6256-firmware is already the newest version (0.3). 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. root@rockpi:~# root@rockpi:~# echo 1 > /sys/class/rfkill/rfkill0/state root@rockpi:~# hciconfig root@rockpi:~#

Decided to reboot because output of the command hciconfig was empty. After reboot:

Added to cron and tested how BT survives on reboot:

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

wodonwong · May 2, 2019, 5:08pm

Hi guys,
Good news.
Try the following link, it works for me.

I have done all the tricks mentioned on this thread w/o accepted result. Still no bluetooth and as a bonus, wifi keeps disconnecting. Any ideas how to proceed? Thanks

@anon77784915, thanks for the tip, I found this command works once to activate the Bluetooth adapter, but failed after?

I have also added the download command to my /etc/rc.local as

#!/bin/sh -e

apt-get install --reinstall rockchip-fstab
