Artem,

It may not be the best way, but I modified simple-agent from tests
with a hardcoded pin, then I run it in the background at startup.
Replace 5555 with your pin.

I tried out the modified simple-agent:

$ sudo passkey-agent_mod
Agent registered
[in separate terminal]
# bluetoothd -dn
...
bluetoothd[10350]: Agent registered for hci0 at :1.7:/test/agent

..but what next - do I specify the bt address of the device I would like to pair with PIN 5555, or?

Thanks, John
