In Figure 11 the sending of one packet and the acknowledgement of this packet is
shown. The loading of payload to the PTX device is not shown in the figure. The PRX
device is turned into RX mode (CE=1), and the PTX device is set into TX mode
(CE=1 for minimum 10 s). After 130 s the transmission starts and is finished after
another 37
s (1 byte payload). The transmission ends, and the PTX device is
automatically turned around to RX mode to wait for the acknowledgement from the
PRX device. After the PTX device has received the acknowledgement it gives an
interrupt to the MCU (IRQ (TX_DS) =>TX-data sent). After the PRX device has
received the packet it gives an interrupt to the MCU (IRQ (RX_DR) =>RX-data
ready).
