In
RX mode (CE=1), and the PTX device is set to TX mode (CE=1 for minimum 10μs). After 130μs the trans-
mission starts and finishes after the elapse of T
When the transmission ends the PTX device automatically switches to RX mode to wait for the ACK packet
from the PRX device. After the PTX device receives the ACK packet it responds with an interrupt to the
MCU. When the PRX device receives the packet it responds with an interrupt to the MCU.
