Hello, The current package 'bluez-5.44-4.el7' doesn't include full support for the Bluetooth device on the Raspberry Pi 3 Model B (BCM43430). That's the reason why you get the Bluetooth MAC address as 'AA:AA:AA:AA:AA:AA' executing 'hciconfig -a'. As stated here <https://www.raspberrypi.org/forums/viewtopic.php?f=66&t=176348>, we need to patch the 'bluez' package with the following 4 patches listed here <https://gist.github.com/pelwell/c8230c48ea24698527cd>, as the Fedora guys do in their 'bluez.spec' file: [...] # Pi3B Patch50: 0050-bcm43xx-Add-bcm43xx-3wire-variant.patch Patch51: 0051-bcm43xx-The-UART-speed-must-be-reset-after-the-firmw.patch Patch52: 0052-Increase-firmware-load-timeout-to-30s.patch Patch53: 0053-Move-43xx-firmware-to-lib-firmware.patch [...] Once applied such patches the real Bluetooth MAC address appears successfully: # hciconfig -a hci0: Type: Primary Bus: UART BD Address: B8:27:EB:37:2C:0D ACL MTU: 1021:8 SCO MTU: 64:1 UP RUNNING PSCAN RX bytes:1550 acl:0 sco:0 events:50 errors:0 TX bytes:1045 acl:0 sco:0 commands:50 errors:0 Features: 0xbf 0xfe 0xcf 0xfe 0xdb 0xff 0x7b 0x87 Packet type: DM1 DM3 DM5 DH1 DH3 DH5 HV1 HV2 HV3 Link policy: RSWITCH SNIFF Link mode: SLAVE ACCEPT Name: 'XXXXXXXXX-rpi3' Class: 0x000000 Service Classes: Unspecified Device Class: Miscellaneous, HCI Version: 4.1 (0x7) Revision: 0xb6 LMP Version: 4.1 (0x7) Subversion: 0x2209 Manufacturer: Broadcom Corporation (15) Also, in order to complement the above patching, it is recommended to add the '--experimental' argument to the Bluetooth daemon in the systemd unit file: # cat /usr/lib/systemd/system/bluetooth.service [Unit] Description=Bluetooth service Documentation=man:bluetoothd(8) ConditionPathIsDirectory=/sys/class/bluetooth [Service] Type=dbus BusName=org.bluez ExecStart=/usr/libexec/bluetooth/bluetoothd --experimental NotifyAccess=main #WatchdogSec=10 #Restart=on-failure CapabilityBoundingSet=CAP_NET_ADMIN CAP_NET_BIND_SERVICE LimitNPROC=1 ProtectHome=true ProtectSystem=full [Install] WantedBy=bluetooth.target Alias=dbus-org.bluez.service Regards. -- Jordi Sanfeliu FIBRANET Network Services Provider https://www.fibranet.cat
