i think there is a bug in ng_btsocket_rfcomm.c. could you please try to 
change ng_btsocket_rfcomm_session_create() function and define local mtu
valiable as u_int16_t instead of int, i.e.

change

static int
ng_btsocket_rfcomm_session_create(ng_btsocket_rfcomm_session_p *sp,
                 struct socket *l2so, bdaddr_p src, bdaddr_p dst,
                 struct thread *td)
{
         ng_btsocket_rfcomm_session_p    s = NULL;
         struct sockaddr_l2cap           l2sa;
         struct sockopt                  l2sopt;
         int                             mtu, error;

to

static int
ng_btsocket_rfcomm_session_create(ng_btsocket_rfcomm_session_p *sp,
                 struct socket *l2so, bdaddr_p src, bdaddr_p dst,
                 struct thread *td)
{
         ng_btsocket_rfcomm_session_p    s = NULL;
         struct sockaddr_l2cap           l2sa;
         struct sockopt                  l2sopt;
         int                             error;
	u_int16_t			mtu;

thanks,
max
