that thread shows how to add bluetooth software, took up about 3MB flash.
opkg install obluez-libs obluez-utils
Then its a matter of using hcitool to configure the beacon. I was after an Eddystone URL beacon and found this site helpfull in setting ut up.
That last page also had a link to a tool to generate the the beacon advertising data. Keep in mind the URL length is limited to 20(?) characters, but there are special characters for common prefix and suffixes, like http:// and .com etc. So I ended up with adding the commands to my rc.local file as shown below, and upon boot the beacon is started.
Other types of beacons (ibeacon etc) just requires a diffent hcitool command with different beacons settings.
