As we have already discussed, we will use hostapd to turn the board into an access point. The recipe for this is available at meta-oe/meta-oe/recipes-connectivity/. Make sure this layer is enabled in bblayers.conf. Also, let's create a separate package group to enable packages to our root filesystem. Let's name it packagegroup-yb-hotspot.bb and add hostap-daemon to it:

RDEPENDS_${PN} = " \
        hostap-daemon \
"

We will add another recipe to it, but wait until we have it created. Also, this is just the difference that we are talking about. Otherwise, you will have to add other lines, such as inherit and SUMMARY and LICENSE, to it in the same way.
