Is it possible to have Bluetooth BR/EDR Out-of-Band (OOB) pairing using the btmgmt tool on Linux? I used the local-oob and remote-oob commands between 2 Linux machines (machines A and B). In machine A, I generate the Hash H_a and Random R_a from btmgmt local-oob command and in machine B I use the same command to generate the Hash H_b and Random R_b.
I configured machine A with
# btmgmt remote-oob -R R_b -C H_b machine_B_BT_address
and I configured machine B with
# btmgmt remote-oob -R R_a -C H_a machine_A_BT_address
I then started the pairing in machine A and in machine B btmon shows that machine A pairing request does not have OOB data flag on. Maybe I am using OOB in a wrong way in this scenario. Can someone tell me how to establish an OOB pairing using this simple scenario?
Thanks!
