Until now, it seems that nobody has ported d-bus to uClinux. Doing that
isn't trivial, because there are several uses of fork() that isn't
available in uClinux. In openwrt, there isn't any mention of d-bus at
all. Most probably, the footprint is too large for memory-restricted
systems. Because of that and the fact there are very few (if any)
projects for embedded systems that use d-bus it's hardly worth the
effort to port it. Bluez has worked quite well for embedded systems with
older versions, but since it ignores the demands of embedded systems
it's probably better to use a different bluetooth stack.
