I am making 802.15.4 protocol on CC2538 board.
In 802.15.4 document, Ack frame doesn't have any address information.
How can get an Ack frame on device or coordinator ?
For example
data frame sending each other, they have to synchronize with ack frame.
but when device or coordinator send ack frame to other side,
there was no information about destination address.
How Ack frame is received on device/coordinator ?
