Nanopi M4 on-board bluetooth not found

[Jerry Jyrer]

Anyone gets Nanopo M4 on-board bluetooth working. Any pointer would be appreciated.

 

Here are what I did: 

-  install Bluetooth component from armbian-config

$ sudo service bluetooth status

I used (Bionic) image from the download section and I could navigate KODI via Bluetooth enabled mouse ... Which image did you used? Have you mage some upgrade from Stretch to Buster? Where is your armbianmonitor -u (which can perhaps tell more).

I think I saw Buster available on the Download page but what I did was simply change /etc/apt/sources.list and apt update & upgrade. Something similar to:

https://linuxconfig.org/how-to-upgrade-debian-9-stretch-to-debian-10-buster

 

somehow armbianmonitor -u returned empty string for me.

I did something similar here:

Thanks for your help.

Simply implement this https://github.com/armbian/build/commit/1541de32b85fa81c82bb549b67a91746ae33230c#diff-fd85d58c8bb1c2923d75fd40b35d907f or start with a clean build if that will give you too much trouble.

Thanks Igor. Pretty newbie here. I changed to nightly firmware and upgrade there to 

 

$ uname -a

Linux nanopim4 5.1.0-rk3399 #5.91.190708 SMP Tue Jul 9 07:58:42 CEST 2019 aarch64 GNU/Linux

 

Things are still not working. Here is $ sudo armbianmonitor -u (it works now :))

Use image from the download section and stay away from nightly / beta sections if you want that things works.

sir, yes sir. : ) I'll definitely try to flash the image from the download section to a new SDCard to just check if BT comes back to work and report here when I get a chance.

By the way, do you have any suggestion for me to just update the core parts in my existing system with the image from the download section? I have things setup already and its kind of painful to re-config things from a fresh install.

I already told you exactly what you have to do, but can't guide in case of troubles. Also you have to remain on stock/legacy kernel. With development kernels (5.1.y) you are on your own. This recipe might work or not.

I got the bluetooth working with a fresh install from the download section to a new microSDCard.  I have rootfs installed in my external hdd. So, I did similar procedures in what nand-sata-install is doing except formatting the external hdd (rootfs). Basically, 

 

- setting the correct UUID and others in /boot/armbianEnv.txt

$ mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr

- setting the correct UUID and mount locations in /etc/fstab

 

The system boots fine. Other things seem to be working okay. BUT the bluetooth is not working : (

 

Here is $ sudo armbianmonitor -u

Helps are appreciated.

Thank you Igor. I finally got it work. Basically, follow your guidance: 

 

$vi /lib/systemd/system/

Description=Bluetooth nanopi

After=bluetooth.target

Type=forking

ExecStartPre=/bin/echo 1 > /sys/class/rfkill/rfkill0/state

SysVStartPriority=99

 

[Install]

WantedBy=multi-user.target

 

$ sudo systemctl --no-reload enable nanopi-bluetooth.service

$ sudo systemctl start nanopi-bluetooth.service

 

BT is working now. : ) 

Trying to get my generic gamepad to work is another story : (

But at least, it's connected.

Hello All,

Just quick question, I hope some of your will be able to answer. I was running Armbian Bionic on legacy kernel for a year on my NanoPi M4 (verion 1) and was able to enable the nanopi-bluetooth.service..

 

Now I have upgraded to Buster server with kernel 5.4 - and cannot get Bluetooth working. I guess this is my mistake to go for server image, and maybe bluetooth is not included in this image by default. 
So my question is should I go back to legacy kernel, or desktop version with 5.4 kernel will be fine, and bluetooth will work with that image. 

I run my NanoPi M4 as headless server, but still need wifi and bluetooth - so that is why I went for Buster server. I do not really want to try all the images myself, because a lot of important services are running on my SBC so I want to make this last shot right now, and choose right here (with WiFi and Bluetooth working, without graphical interface):

 - go back to images based on legacy kernel

 - use desktop buster image on kernel 5.4

 - stay on my current image of Buster server kernel 5.4 and add Bluetooth service myself (if someone can point me into solution).

 

will appreciate any help here, thanks.
