Hi,
WIth Btattach, ioctl fails to set flags from 32-bit user space to 64-bit
kernel. ioctl fails with ENOTTY.
static int attach_proto(const char *path, unsigned int proto,
unsigned int flags)
{
int fd, dev_id;
fd = open_serial(path);
if (fd < 0)
return -1;
if (ioctl(fd, HCIUARTSETFLAGS, flags) < 0) {
perror("Failed to set flags");
close(fd);
return -1;
}
.....
Kind regards,
J.J.
