I'm doing my first Bluetooth app, and I have a specific question and a
general question:
1/ Where can I find documentation on the BlueZ API?
I've searched and haven't found anything yet.
2/ I've captured a trace of an existing conversation off of my Android phone,
and I'm trying to re-create it via my own app using BlueZ.
I've gotten to the point of trying to do an LE Create Connection
via hci_le_create_conn()
and my first stumbling block is the value of the 'peer address type'.
From my investigation, I need to use the 'public' address type
which according to
the spec, and Wireshark is a value of 0x00, but bluetooth.h defines
'public' as 0x01
(as per the following extract). Can anyone explain it to me?
#define BDADDR_BREDR 0x00
#define BDADDR_LE_PUBLIC 0x01
#define BDADDR_LE_RANDOM 0x02
TIA
Fulko

why not use the bluetoothd D-Bus GATT APIs for your application. It will create all needed connections. Manually doing HCI is the wrong approach since that is owned by the kernel.
