[AC Question]

It is reported that in some versions of Lollipop 5.1.1 Multicast was not included to give better battery life.If Multicast is not included how do I find a custom ROM to fix the problem?
I am running Fresh KDS and Square POS. They need to find each other on the LAN and it appears that WiFi Multicast is not included or disabled in the version of Lollipop on the Pendo 10 tablet. The tablet has a Rockchip processor. A cheaper version of the Pendo 10 with A33 Allwinner processor works fine.
