[Raspberry Pi4] Bluetooth not enable/not working

kev-dev1 commented 4 years ago

Bluetooth on Raspberry Pi4 not working to enable. Can we add Bluetooth for Raspberry Pi4.

danialbehzadi commented 3 years ago

Repeat this one. This should not be so hard, since konstakang and arpi kernels support Bluetooth well.

danialbehzadi commented 3 years ago

Adding BT_BCM to kernel config seems to be the Bluetooth magic: https://github.com/lineage-rpi/android_kernel_brcm_rpi/commit/4a2059b200425c15e3a590d874cd447d1bf16054

Hi, I've tried to enable bluetooth on the next branch but without success. These are the steps I've performed:

kernel/glodroid-broadcom/arch/arm64/configs/bcm2711_config updated with changes described for lineageos_rpi4_defconfig adding various CONFIG_BT...
device/glodroid/rpi4/device.mk updated calling bluetooth.mk instead of no-bluetooth.mk
common/bluetooth/boardconfig.mk updated adding first only BOARD_HAVE_BLUETOOTH_BCM

but when I try to enable bluetooth, I get several fails and moreover using adb shell dumpsys bluetooth_manager name and address are always null. I have then tried other changes:

device/glodroid/common/bluetooth/boardconfig.mk updated adding also BOARD_BLUETOOTH_BDROID_BUILDCFG_INCLUDE_DIR and BOARD_CUSTOM_BT_CONFIG but this means adding the folder with files as for android-rpi with bdroid_buildcfg.h, bt_vendor.conf and vnd_rpi4.txttoo
device/glodroid/common/bluetooth/bluetooth.mk updated with bt_vendor.conf:system/etc/bluetooth/bt_vendor.conf and also android.hardware.bluetooth@1.0-impl and android.hardware.bluetooth@1.1-service.btlinux or alternatively using 1.0-service and 1.0-impl but with the same result

I ultimately changed also device/glodroid/common/init.common.rc moving and changing the rfkill management as for android-rpi but without success.

My apologies for the request, I know you said it should not be so hard, probably I am just missing something more trivial which is not present in the GloDroid tree. I've not changed anything more than what I have just described here. Thank you for your support!

I've submitted a minor fix that should help debugging it further: https://android-review.googlesource.com/c/platform/system/bt/+/1896708

rsglobal commented 2 years ago

Ok, here is my current progress on bluetooth. All necessary kernel modules is up, but still I can't see no devices to pair.

Interesting, did you not add BCM4345C0.hcd? I just followed all the steps in android-rpi:

https://github.com/android-rpi/device_arpi_rpi4/commit/dde16ec3f1b4f60ecb5c4c40de4f68c75e9ed23b

When you do adb shell dumpsys bluetooth_manager can you see the name and the address?

ghost commented 2 years ago

I see only the name, but the address is always null. These are interesting things I can see from my log:

I've got some initial initialization but it crashes soon with:

rsglobal commented 2 years ago

Interesting, did you not add BCM4345C0.hcd?

No, thanks for suggesting. Let me try.

rsglobal commented 2 years ago

It seems to work:

Bluetooth Status
  enabled: true
  state: ON
  address: DC:A6:32:0F:C3:90
  name: rpi4
  time since enabled: 00:00:10.673

rsglobal commented 2 years ago

It still crashes during pairing, but at least there is a progress.

ghost commented 2 years ago

Nice! But then or I'm missing some kernel modules or I'm doing something wrong somewhere else because I still do not see the address. Can you tell me which CONFIG_BT... you put on bcm2711_config and defconfig?

rsglobal commented 2 years ago

I haven't enabled any extra configs. Just that patch (next branch was updated). Ensure you've executing m images, not just m before flashing.

I got it! And I'm pairing without crashes! We have Bluetooth up & running here!

Now I do not have time to put all the changes, I have to clean a bit because I was trying a lot of things but on Monday I will post everything.

Thank you very much for the help and enjoy your weekend!

I suspect I used wrong firmware. Now I am trying official: https://github.com/RPi-Distro/bluez-firmware/blob/e7fd166981ab4bb9a36c2d1500205a078a35714d/broadcom/BCM4345C0.hcd

rsglobal commented 2 years ago

Much stable now. I was able to pair my phone. Next branch updated.
