Bluetooth stopped working at 3.59.6.20210911

[in-voker]

Describe the bug
Since version 3.59.6.20210911 the bluetooth doesn't work anymore at my ELV Charly (RPi3).
I set the /etc/config/enableBluetooth file correctly and also tired to start /etc/init.d/S40bluetooth start manually.
On version 3.59.6.20210911 the message "WARNING: bluetooth setup failed" is appearing.

Steps to reproduce the behavior

1. installed fresh (without any backups) RaspberryMatic-3.59.6.20210703-rpi3 which is working without any issues
2. installed fresh (without any backups) RaspberryMatic-3.59.6.20210807-rpi3 which is working without any issues
3. installed fresh (without any backups) RaspberryMatic-3.59.6.20210911-rpi3 which shows that bluetooth is not able to beeing enabled
4. installed fresh (without any backups) RaspberryMatic-3.59.6.20211009-rpi3 which shows that bluetooth is not able to beeing enabled

*installed fresh = flash rom directly with win32diskimager on sd

Expected behavior
the start of hcitool via ssh should work to be able to use lescan

Screenshots
i didn't take any screenshots because there isn't anything special to see. bluetooth is just not working with the newer versions...

System information:

• RaspberryMatic Version: RaspberryMatic-3.59.6.20210807 (currently using this version because this has working bluetooth support)
• Used Hardware: RPi3 (ELV-Charly)
• Used HomeMatic RF-Module: RPI-RF-MOD

Additional context
i am a bit irritated because i don't find any other guys reporting this. this is the reason why I waited that long...
Because it flashed a completed fresh rom on SD without any additional stuff from myself i am pretty sure it's nothing wrong with my hardware. everything works well with the 20210807 and before...

I have exactly the same problem!
Since version 3.59.6.20210911 bluetooth doesn’t work on an ELV Charly (RPi3).

I checked /etc/init.d/S40bluetooth and tried to start bluetooth manual by the CLI.
It seems to be that the necessary tools hciattach and hciconfig are missing.

If i enter hciattach or hciconfig in the CLI, i get „not found“.

For my project I use l2ping, this tool is also missing.

Hello,

i've the same issue with the Raspberry and i think that the issue could be that /usr/bin/hciattach is not existing anymore but this tool is needed to start /etc/init.d/S40bluetooth

Hi,

I found out the following:

Change log RaspberryMatic 3.59.6.20210911

• updated buildroot to latest stable 2021.08 version.

There is a change from buildroot 2021.05 to 2021.08.

Change log buildroot 2021.08-rc1, released August 3rd, 2021:

• Many features of the bluez5_utils package have been made optional, and default to disabled. Users of bluez5_utils are encouraged to review their configuration.

In menuconfig:
Target packages -> Network applications

• in the tree ‚bluez-utils‘ is selected
  ‘install deprecated tools’ is also selected but NOT ‘build tools’

‘build tools’ contains hciattach and l2ping!

I tested it in my own build environment by adding the package ‘build tools’ and compiling it.
After this bluetooth started working.

This issue is still in RaspberryMatic 3.61.7.20220115.

After this bluetooth started working.

Thanks for the investigation. Are you able to submit a PR on that or at least show a diff against the defconfig? That would be highly appreciated.

I compared the from ‘menuconfig’ generated defconfig (RaspberryMatic 3.61.7.20220115), there is only one difference:

original:

BR2_PACKAGE_BLUEZ5_UTILS_TOOLS is not set

patched:
BR2_PACKAGE_BLUEZ5_UTILS_TOOLS=y
