You're not compiling a package, you're compiling a recipe named
obexpushtest whose output is packages (one of which is named the same as
the recipe, hence the confusion).

But here, you're adding a package into an image. Effectively, the first
and second commands you ran don't do the same thing.

You should probably inherit bin_package but override do_install
(otherwise you'll have an issue with the do_install task coming from the
bin_package bbclass trying to pack your whole ${WORKDIR} (S) which
include way too many files you're not interested in).

No need for _append since the following is the only thing your recipe
will do, so better just override do_install.

Here's the issue, you put your file into the obexpushtest-example and
I'm pretty sure that your obexpushtest package is actually empty and by
default empty packages are removed, hence why the image recipe can't
include this package.

IMHO, no need for your PACKAGES and FILES variables as the default will
put your binary in the obexpushtest package, and since your recipe isn't
creating any other package (explicitly), I don't see the use for a new
package.
