When having such a state:
Running as root
/usr/sbin/hciconfig hci0 down
return immediately w/o resetting the device

#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <stdio.h>
#include <sys/ioctl.h>
//#include <bluetooth/hci.h> evil header, can't be used standalone
/* HCI ioctl defines */
#define HCIDEVUP _IOW('H', 201, int)
#define HCIDEVDOWN _IOW('H', 202, int)
#define HCIDEVRESET _IOW('H', 203, int)
int main (int argc, char ** argv) {
if (argc > 1) {
int fd = open (argv[1], O_RDWR);
if (fd < 0) {
perror ("open");
return 1;
}
if (fd > -1 && ioctl (fd, HCIDEVDOWN)) {
fprintf (stderr, "Down fails, trying reset..%d\n",
ioctl (fd, HCIDEVRESET));
}
close (fd);
}
return 0;
}
when running as
./hci-reset /dev/rfcomm0
open: No route to host
So far it didn't do what the 'Offline mode' does ..
