Hi,
Anyone know which part of linux kernel processes the LMP au_rand and
LMP not_accepted event?
I want to modify the Bluetooth kernel code so that when it receives
LMP not_accepted event, it will do re-pairing.
Thanks,
Victor

Hi Victor,
As I can read in the code the hci_auth_complete_evt() call mgmt_auth_failed() on failure. The mgmt_auth_failed() function just prints
The fail status number. You can add your own code to do re-pairing several times.
Thanks,
Doron

Hi Doron,
Will the hci_auth_complete_evt() function in net/bluetooth/hci_event.c
handle the hci error code?
Thanks,
Victor
Hi Victor,
The LMP not_accepted event will lead to Authentication failure.
Some devices will then initiate disconnection with error code :
Authentication Failure error code (0x05).

Hi Marcel,
When LMP_not_accepted is received by Bluetooth Chip's firmware, it
will send a HCI event to the linux kernel bluetooth portion. Do i
understand correctly? What is the HCI event name?
Thanks,
Victor

LMP is implemented in the Bluetooth chip's firmware and not the kernel.
