hcitool scan does not find my bluetooth device
man hcitool lists the following option:
-i <hciX>
The command is applied to device hciX , which must be the name of an
installed Bluetooth device. If not specified, the command will be sent
to the first available Bluetooth device.
I suspect your “small device” bluetooth chip is not the default hci0, so hcitool doesn't send commands to it unless you say so. To display available local devices, run:
hcitool dev
This will show a list of devices with their device names. Pick the one you want and execute e.g.
hcitool -i hci1 scan
