In these notes "xx:xx:xx:xx:xx:xx" means the MAC address of the remote bluetooth device

Reset Bluetooth Adaptor


sudo hciconfig hci0 reset

Restart Bluetooth Service


sudo invoke-rc.d bluetooth restart

List Bluetooth Adaptors


hciconfig

Scan for Bluetooth devices


hcitool scan

To then connect to one of the found devices  you can use this:


sudo bluez-simple-agent hci0 xx:xx:xx:xx:xx:xx

Make The Raspberry Pi Discoverable


sudo hciconfig hci0 piscan

You will now be able to search and find the RPi from other devices such as windows "Add A Device" (development tip – if you've previously connected you'll need to remove it from Windows Devices for it to be able to found it again by Add A Device)

To allow the connection to complete you need to also do the following step to allow a remote device to actually connect:


sudo bluetooth-agent 1234

1234 is the pairing code for it to use, but this will can be automatically overridden by a randomly selected code displayed on both devices

Discover Bluetooth Devices


hcitool scan

List Previously Paired Devices


bluez-test-device list

(This will appear to do nothing if there are no devices).

Remove Previously Paired Device

You will need to get the devices MAC address by using the List command

If you need to disconnect it first:


bluez-test-device disconnect xx:xx:xx:xx:xx:xx

Then


bluez-test-device remove xx:xx:xx:xx:xx:xx

Ping Device


sudo l2ping -c 1 xx:xx:xx:xx:xx:xx
