Bluetooth problem with Pi Zero W - Mac address AA:AA:AA:AA:AA:AA

Hello

I have a problem with the internal bluetooth controller of my Pi Zero W.
Mac address is AA:AA:AA:AA:AA:AA !!

I found this errors in dmesg

What can I do ?

Got same problem on my RPi 3b+, the address of bluetooth module is all 00:00, the scan don't working. I guess, the internal bluetooth module is just not compatible with kali linux.

Seems that BCM43430A1.hcd firmware file is missing in some of this packages packages:

Code:

kalipi-re4son-firmware bluez-firmware pi-bluetooth+re4son

You can download it manually and place into /lib/firmware/brcm/BCM43430A1.hcd

Code:

wget https://github.com/RPi-Distro/bluez-firmware/blob/master/broadcom/BCM43430A1.hcd -O /lib/firmware/brcm/BCM43430A1.hcd

but this still not resolving the issue. I'm not sure what actually wrong.
You can check the another image Kali Linux RPi0w Nexmon P4wnp1 Aloa where bluetooth works correctly and look what is missing.

I've tried Kali Linux RPi0w Nexmon P4wnp1 Aloa and bluetooth works correctly:

Code:

# lsb_release -a No LSB modules are available. Distributor ID: Kali Description: Kali GNU/Linux Rolling Release: 2019.2 Codename: n/a # uname -a uname -a Linux kali 4.14.80-Re4son+ #1 Fri May 17 20:25:41 UTC 2019 armv6l GNU/Linux

Only one build script in kali-arm repo rpi0w-nexmon-p4wnp1-aloa.sh have manage the bluetooth firmware file:

Code:

rpi0w-nexmon-p4wnp1-aloa.sh line 519: cp "${basedir}"/../misc/brcm/BCM43430A1.hcd "${basedir}"/kali-${architecture}/lib/firmware/brcm/BCM43430A1.hcd

This probably a bug, cause all list images for raspberry pi zero W and 3b should have this file.

I've put bluetooth firmware file BCM43430A1.hcd into kali-linux-2019.2-rpi0w-nexmon.img image and get this. As you can see, btattach correctly enumerates bluetooth device but after we get timeout and hciconfig shows bluetooth device with zeroes MAC address and scans not working.

I've build a new image with bluetooth fix:

https://zhovner.com/tmp/kali-linux-n...0-04-54.img.xz

Just enable hciuart service after boot:

Code:

systemctl enable --now hciuart
