Can't start Bluetooth on Orange Pi Zero Plus 2 H5

Spider · February 29, 2020

Hello!

I'm tryiing to make iBeacon scan service. But can't make Bluetooth work on OPi0+2H5.

I'm using "Armbian_20.02.1_Orangepizeroplus2-h5_bionic_current_5.4.20_minimal.img" as OS, but no hci devices in system after start. I reded many topics from this forum and nothig helps me. Can't start BT

Is BlueTooth part work on this board? Can I use it?

I need only "lescan" functional....

Thx, for reply. But I finaly launch BT device.

Next steps:

1. Disable uart1 overlay

2. copyed firmware for ap6212 from last broadcom package into /lib/firmware/bcm....

3. modified ap6212-bluetooth

- at start add:

        devmem2 0x1f00060 b 1
        echo 10 > /sys/class/gpio/export
        echo out > /sys/class/gpio/gpio10/direction
        echo 0 > /sys/class/gpio/gpio10/value
        echo 1 > /sys/class/gpio/gpio10/value
        sleep 0.1

- at end add: (else after soft reboot wifi will not work)

        devmem2 0x1f00060 b 0
        echo 10 > /sys/class/gpio/export
        echo out > /sys/class/gpio/gpio10/direction
        echo 0 > /sys/class/gpio/gpio10/value

        sleep 0.1

        echo 10 > /sys/class/gpio/unexport
        sleep 0.1

Hi, could you elaborate on your fix?

How do I disable the uart1 overlay
Which firmware did you copy again?

Thanks

Hi , i have a same problem with opiz+2 Mainline kernel 5.4.2x i could not find ap6212-bluetooth file (i did it before on legacy kernel), now i have only bluetooth file. I try to edit this file but nothing change. Could you a bit clear how to success with bluetooth. Thanks

Bluetooth init success with Orange pi zero plus 2 Mainline kernel 5.4.28

i solve problem with these steps:

1) install bluetooth support from armbian-config

2) install devmem2 and compile if not installed

wget http://free-electrons.com/pub/mirror/devmem2.c
gcc ./devmem2.c
mv ./a.out /usr/local/bin/devmem2

3) add modules bluetooth and hci_uart to /etc/modules

4) remove bluetooth service (we will add new script)

update-rc.d bluetooth remove

5) remove blutooth init script (editing not worked for me)

rm /etc/init.d/bluetooth

6) copy modified bluetooth init script file(ap6212) to /etc/init.d/

7) edit permissions

chmod +x /etc/init.d/ap6212

8) enable service script

systemctl enable ap6212

9) reboot

after reboot probably you will see your service succefully running

systemctl status ap6212

Q: what is difference between ap6212 and bluetooth service init?

A: added gpio controls

Now you can attach uart with sucess

hciattach /dev/ttyS1 any 115200 flow bdaddr 00:90:4c:c5:12:38
hciconfig hci0 up

i could not change mac adress device always setup with AA:AA:AA:AA:AA:AA

if you can please let me know.

Thanks

I've followed the steps here on mainline kernel 5.8.5. $systemctl status ap6212 looks similar to yours. However $hcitool dev cannot find devices. I can't find my Bluetooth mac address.

Any thoughts or help would be great!
