Bluetooth interface control in C code ( Linux OS )

Question

Normally I can control the interface through the command

 hciconfig hcix up/down 

Can I do this by using c code ?

Is there sample code I can refer to ?

Thanks

Answer 1

You can use the c code for hciconfig itself. Just download the BlueZ source and open tools/hciconfig.c and use the following functions:-

static void cmd_up(int ctl, int hdev, char *opt)
{
    ...
}

and

static void cmd_down(int ctl, int hdev, char *opt) 
{
    ... 
}
