Hardware
First you have to get a compatible hardware. Currently there are 3 solutions:
- Get a Wireless extension board from armadeus systems (only available for APF27)
- Get a cheap USB<->Bluetooth adapter (requires an USB Host port)
- Get a RS232<->Bluetooth adapter

Usage
Bring up
- Make sure your hardware is connected to the APF. If using an USB dongle, load corresponding driver:
# modprobe btusb Bluetooth: Core ver 2.14 NET: Registered protocol family 31 Bluetooth: HCI device and connection manager initialized Bluetooth: HCI socket layer initialized Bluetooth: Generic Bluetooth USB driver ver 0.4 usbcore: registered new interface driver btusb
- Check if Bluetooth interface was detected:
# hciconfig hci0: Type: USB BD Address: 00:00:00:00:00:00 ACL MTU: 0:0 SCO MTU: 0:0 DOWN RX bytes:0 acl:0 sco:0 events:0 errors:0 TX bytes:0 acl:0 sco:0 commands:0 errors:0
- If interface is DOWN, bring it up:
# hciconfig hci0 up piscan
- Check your Bluetooth device is correctly initialized:
# hcitool dev Devices: hci0 00:10:60:D1:92:0F
