Bluetooth
  • Utilite2 features Bluetooth 4.0 interface implemented with Atheros QCA6234. The Bluetooth device interfaces the Host Controller Interface (HCI) via serial connection (UART). The serial BLuetooth device currently is not attached to the Buetooth stack automatically.
Workaround #1: Attach the serial Bluetooth device via UART HCI to the Bluetooth stack manually:
utilite@utilite-desktop:~$ sudo hciattach -s 115200 /dev/ttyHS0 ath3k 3000000
Device setup complete
Workaround #2: Add a reference to the Bluetooth serial device to the /etc/bluetooth/uart file in order to attach it to the Bluetooth stack at boot time. Reboot the Utilite2.
utilite@utilite-desktop:~$ su
Password: 
root@utilite-desktop:/home/utilite# echo "/dev/ttyHS0 ath3k 3000000" > /etc/bluetooth/uart
root@utilite-desktop:/home/utilite# cat /etc/bluetooth/uart 
/dev/ttyHS0 ath3k 3000000
root@utilite-desktop:/home/utilite# reboot
Fix: available since 30-Jul-2015 release version.
