I am using the nRF24le1 in Enhanced Shockburst mode.
The datasheet describes how it is possible to upload acknowledge packets, W_ACK_PAYLOAD, to the TX FIFO. And then the PRX will send the acknowledge as soon as it receives a packet.
I would like the PRX to give immediate response to back to the PTX, based on the content of the packet is has just received.
Is it possible for the PRX to upload W_ACK_PAYLOAD as soon as it receives a packet and send acknowledgement back with reply to the packet from the PTX? From my own testing, it seems like there is a time-window of about 120us, between receiving a packet and before the a W_ACK_PAYLOAD has to uploaded.
Alternatively, I will have to send two packets from the PTX: 1) The first with data to PRX. 2) The next, (a dummy), to get an acknowledgement with feedback on the data in the first packet.
In other words: Is Enhanced Shockburst mode possible without pre-loaded acknowledgement packets? And if so, how big is the time-window?
