Allows to connect from Android to a
painlessMesh network and act
like a node. The app can connect, request routing info (NODE_SYNC_REQUEST)
and send single (SINGLE) and broadcast (BROADCAST) messages. There is no
support for (TIME_DELAY), (TIME_SYNC) and (NODE_SYNC_REPLY). The app is
connecting to the closest painlessMesh AP.
Due to restrictions of Android, painlessMesh can not have AP and STA mode
running in parallel. Since Android 6 it requires the location service
permission from the user to be able to scan for Wi-Fi networks.
