mystery dissolves, when you watch it byte-wise and in hex notation !
thanks for the "strace" tip. I found the error soon:
9687 bind(5, {sa_family=3D0x1f /* AF_??? */,
sa_data=3D"\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00"...}=
, 10)
=3D 0
pand initialises the l2a-struct with "0"s, before binding.
static bdaddr_t src_addr =3D *BDADDR_ANY; // where BDADDR_ANY is
{0,0,0,0,0,0}
l2a.l2_bdaddr =3D src_addr;
if (bind(sk, (struct sockaddr *) &l2a, sizeof(l2a)))
thats what I forgot, a simple=20
memset(&l2a, 0, sizeof(l2a));
makes the code working.
the padding seems to make no problems.

I think it is better if you use
bacpy(&l2a.l2_bdaddr, BDADDR_ANY);
