Automatic pairing

Automatic pairing

[Jonathan Nichols]

Hello,

    I want to use bluez to set up a linux machine to automatically
pair with devices that initiate pairings.  What is the recommended way
of doing this?  I noticed that there is an autopair.c in bluez 5.5,
but it isn't clear how to use it.  Is there any example code that
shows how to use this file?

    Any other suggestions for setting up a linux machine to
automatically pair with any device that initiates a pairing?

Thanks,

jon

Just to follow up ... I didn't quite mean that I wanted to pair with
any device that initiates a pairing.  Ideally, I would like to hard
code a non-trivial pin, so that the linux machine automatically pairs
with any device that knows that pin.

Please have a look at the "simple-agent" tool in the bluez tree. The
bluez bluetoothd daemon allows dbus clients to provide "agents" which
are called for any incoming connection. This way you can either accept
or deny a new connection.
Agents are also asked for pin-input so you can always use your static
fixed PIN, if you want. This way, remote devices that don't know the
PIN will be automatically recjected.
