getting address type from scan result

getting address type from scan result

[Ordit Gross]

hi,

Up till now the peripheral device we worked against was configured
with public address,
now it might also be random (both BDADDR_LE_RANDOM, BDADDR_LE_PUBLIC).
The type of address is needed to connect correctly to the device
(using l2cap_connect).

How can I get the address type from the scan report?
I'm currently using bluetoothctl, which seems not to expose this
information in Device1 interface.
thanks in advance! and happy holidays

just to clarify, the needed information is:
> HCI Event: LE Meta Event (0x3e) plen 37                                                                                                                       #324 [hci0] 1064.855314
      LE Advertising Report (0x02)
        Num reports: 1
        Event type: Connectable undirected - ADV_IND (0x00)
        Address type: Random (0x01)
        Address: 5B:6C:86:BE:2C:40 (Resolvable)

the only way I could think of is by opening an hci socket.. is there
any other way?
thanks for your help!

it is in the Device1 interface for the Identity Address. Why are you going to connect an L2CAP socket in the first place for a LE device.

hi Marcel, appreciate your answer, I am using code sample
btgatt-client.c which uses function:
static int l2cap_le_att_connect(bdaddr_t *src, bdaddr_t *dst, uint8_t
dst_type, int sec)
is there a way to implement connect without stating the dst_type?
thanks again
