BlueZ does not require authentication

I work with BlueZ 3.x. I have a built-in linux device and I need to send and receive files using bluetooth technology using Obex . (Note: BlueZ 4.x does not even compile on our particular platform.)

I don’t need PIN authentication, I don’t even want this. It should be as simple as possible for the end user.

I tried to set security none in hcid.conf , but it does not work.

So my question is:

  • Can I send and receive files using Obex on bluetooth?
  • How to do it?
  • Does authentication require Bluetooth devices (such as a mobile phone)?

  • You can use OBEX protocoll for this, but you will also need an FTP or OPP profile (and GOEP, SPP and GAP, as they depend on them).
  • The documentation can be found at BT SIG bluetooth.org, but you must be a member. I think some of the documentation is also available to non-members, go there and see.
  • Yes (if we are talking only about mobile phones)
