nRF24LE1 Preliminary Product Specification
Activate PTX mode by setting the rfce bit in the RFCON register high. If there is a packet present in the TX
FIFO the RF Transceiver enters TX mode and transmits the packet. If Auto Retransmit is enabled, the
state machine checks if the NO_ACK flag is set. If it is not set, the RF Transceiver enters RX mode to
receive an ACK packet. If the received ACK packet is empty, only the TX_DS IRQ is asserted. If the ACK
packet contains a payload, both TX_DS IRQ and RX_DR IRQ are asserted simultaneously before the RF
Transceiver returns to standby-I mode.
If the ACK packet is not received before timeout occurs, the RF Transceiver returns to standby-II mode. It
stays in standby-II mode until the ARD has elapsed. If the number of retransmits has not reached the ARC,
the RF Transceiver enters TX mode and transmits the last packet once more.
While executing the Auto Retransmit feature, the number of retransmits can reach the maximum number
defined in ARC. If this happens, the RF Transceiver asserts the MAX_RT IRQ and returns to standby-I
mode.
If the rfce bit in the RFCON register is high and the TX FIFO is empty, the RF Transceiver enters Standby-
II mode.
