OPZ+2 H5 onboard bluetooth support?

Larry Bank · November 20, 2017

Is there some DT overlay to enable or some software to install to use the onboard bluetooth radio of the Orange Pi Zero Plus 2?

No proper quick hack solution yet. https://github.com/armbian/build/commit/d95d45f20947661c17d3d1ee3b1ba964de677cb4

Hello everyone,

I managed to have armbian running on my H5, nearly everything is fine so far, boots from NAND, have NodeJs perfectly running, but i do need to have Bluetooth support, basically that was a reason why i got the board. Anyone can tell me how to enable BT support from command line please?

Regards,

Evi

It is not implemented yet. You can use some USB based until then - it should work out of the box. You only need to enable Bluetooth support within armbian-config or install appropriate userspace packages manually.

Is there an issue for this or some other way I can track it's status?

I'd really like to help and get this working, but I am having trouble getting started. I have setup the build environment and have created images for the OPiZero2+H5 but have no idea what to try to get BT up and running. There are scattered hints here in the forums, but most are over my head.

Is there a resource that would guide me in the right direction?

Thanks.

Happysax I am trying to contribute also and I just came across in the armbian doc with this:

https://docs.armbian.com/Process_Contribute/

I’m still learning, yet see if that would help

enable overlay uart 1

and add

param_uart1_rtscts=1

to armbianenv.txt

and adjust /etc/init.d/ap6212-bluetooth so it looks like this

# Start patching
        rfkill unblock all
        echo "0" > /sys/class/rfkill/rfkill0/state
        echo "1" > /sys/class/rfkill/rfkill0/state
        echo " " > /dev/$PORT
        devmem2 0x1f00060 b 1
        echo 10 > /sys/class/gpio/export
        echo out > /sys/class/gpio/gpio10/direction
        echo 0 > /sys/class/gpio/gpio10/value
        echo 1 > /sys/class/gpio/gpio10/value
        sleep 0.1
        hciattach /dev/$PORT bcm43xx 115200 flow bdaddr $MAC_OPTIONS
        hciconfig hci0 up

and reboot

oh you might need to install devmem2

happyzax · May 6, 2018

Thanks for this precious information!

I've had this bleeding Orange Pi Zero 2+ H5 for like a year now, and finally someone has figured out the BT. Excellent work!

TonyMac32 · May 7, 2018

@Myy I wonder if this might be able to be adapted for Tinker mainline bluetooth?

So much time so little to do!... Strike that, reverse it.

On debian devmem2 not available. Debian users should install it from http://launchpadlibrarian.net/153545374/devmem2_0.0-0ubuntu1_arm64.deb

thc013 · May 7, 2018

all this could be implanted in the dts file

its only uart1 on default and pin 10 enabled

oh yeah and the clock

Aha ! I'll try this tonight ! Though I forgot the chip they used in the Tinky. It's a broadcom too ? I'll take a look.

TonyMac32 · May 8, 2018

It's a Realtek 8723BS, but operates the same way. (any guess what BS stands for? ;-) ). I actually think we should wipe out the DTS entry that's there for it and start over, since that one appears to be tied somehow to the Rockchip special rfkill system. I was able to get it to start the handshake by toggling the gpio pins associated, so this might be a template for getting to to work properly. Ok, enough off-topic. :-D

thc013 · May 17, 2018

huh wipe out you only have to add the clock and extra gpio pin in the dts file .

I use this solution what you had wrote,but the effect is not significant. my img is Armbian_5.42_Orangepizeroplus2-h5_Debian_stretch_dev_4.16.img .

but when i reboot or use this

You have to install devmem2

Thank you for your reply！

but I'am already install devmem2,I think my mistake is somewhere else.

i use this script to test:

#!/bin/bash
PORT="ttyS1"
MAC_OPTIONS="43:29:B1:55:01:01"
rfkill unblock all
echo "0" > /sys/class/rfkill/rfkill0/state
echo "1" > /sys/class/rfkill/rfkill0/state
echo " " > /dev/$PORT
devmem2 0x1f00060 b 1
echo 10 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio10/direction
echo 0 > /sys/class/gpio/gpio10/value
echo 1 > /sys/class/gpio/gpio10/value
sleep 0.1
hciattach /dev/$PORT bcm43xx 115200 flow bdaddr $MAC_OPTIONS
hciconfig hci0 up

result:

root@H5:~# ./blue.sh
/dev/mem opened.
Memory mapped at address 0xffff9eab1000.
Value at address 0x1F00060 (0xffff9eab1060): 0x1

bcm43xx_init
Initialization timed out.
Can't get device info: No such device

devmem2 seems are correct... I don't know what to do now

Don't use "dev" branch images because they have broken overlays. Only "next" branch images with kernel 4.14 may work.

Thank you ！

I'm so sad , Because when i use Armbian_5.38_Orangepizeroplus2-h5_Ubuntu_xenial_next_4.14.14.img, This problem has arisen "Starting kernel" reboots.

Now i try to use the nanopi-neo-plus2 image . If I successfully solve, I will feedback in time

zhen8838 · May 29, 2018

My problem has been solved，I compiled a new image ：Armbian_5.45_Orangepizeroplus2-h5_Debian_stretch_next_4.14.44.img .

thc013 · June 11, 2018

thnx zhen8883

i didm't notice that bluetooth was again not working . last weeks i fighting with spi and a nrf20l01 i can't get it working with mysensors and the rf24 lib works a bit

but i tried al armbians from 5.38 till 5.46 and kernels from 4.14.14 till 4.14.48 and suddenly it is not working anymore . and i saw your blogs and tried a orangepi distro and works right away when activate it .

only thing that was mentioned in the mailine bluetooth thread was that the rts and cts are not bind to uart1 in the dts file so i include them and and put them both in the main dts but no effect

i got the info from other threads but hte problems are similar i guess it is the binding of uart1 or the wake up routine is not going well

thc013 · June 12, 2018

a bit futher

make sure

devmem2 0x1f00060 b 1

give as result

Value at address 0x1F00060 (0xffff9eab1060): 0x1

happyzax · June 20, 2018

Just installed the latest nightly, did an upgrade and sure enough BT is not working anymore. The fix no longer works. Dang! Almost had it!
