We are using your nRF24l01+ chip in one of our products. we are using 1 nRF as receiver and 5 nRF's as transmitters.
While trying to use the chip with multiciever configuration, the receiver is not getting the data from transmitters every time. Obviously there will be some frames lost in air, but the difference for us is very noticeable. Approximately only 1 in every 20 times, the data is processed. In our application, dropping the occasional frame is non-consequential; we only need the latest data from the sending devices to plot it on a live display.
Our target is to get data from all transmitters every 15ms or faster. We are getting it only every 200ms or more.
The situation gets worse if we request ACK from Transmitter side. The transmitter is sending frames every 100ms or more in this case. We have to transmit the payload with acknowledgement every now and then to see if receiver is present or not for sleep management.
