EBI_TYPE_ACK packet always returns ‘success’ for the broadcast or
group message transmission.
In unicast message transmission, if a short- address of a receiver
modem ID does not exist, the data are transmitted as a broadcast
message in order to fix the short- address problem. Accordingly, even the
modem having identical modem ID with a receiver does not exist in the
PAN, the transmission result can be returned as ‘success’.
