nRF24L01+ Product Specification

Figure 16. Timing of Enhanced ShockBurst™ for one packet upload (2Mbps)

In Figure 16. the transmission and acknowledgement of a packet is shown. The PRX device activates RX

mode (CE=1), and the PTX device is activated in TX mode (CE=1 for minimum 10µs). After 130µs the

transmission starts and finishes after the elapse of TOA.

When the transmission ends the PTX device automatically switches to RX mode to wait for the ACK packet

from the PRX device. When the PRX device receives the packet it sets the interrupt for the host MCU and

switches to TX mode to send an ACK. After the PTX device receives the ACK packet it sets the interrupt to

the MCU and clears the packet from the TX FIFO.
