nRF24L01+ mistake in specification?

[Carlos Cuevas]

Hello, I think there's a mistake in page 35 of the specification, it says that if Auto Retransmit is disabled (that meaning Auto Retransmit Count = 0 in SETUP_RETR register) then it doesn't even goes to Rx mode to wait for ACK, it's not true as I've succesfully disabled auto retransmit and I'm still getting ACKs from PRX.

I agree with you, there is an error in the flowchart.

For (legacy) ShockBurst operation the auto acknowledgement (EN_AA) should be disabled as explained in Appendix B in the product specification (this is not shown in the flowchart). Alternatively for Enhanced ShockBurst mode the W_TX_PAYLOAD_NOACK can be used, however this will include a 9bit packet control field which is not compatible with (legacy) ShockBurst.
