nRF24L01+ Possible to produce continuous bitstream?

[John]

I would like to use the nRF24L01+ for a telemetry project that requires broadcast at 100% duty cycle at a fixed bitrate. Ideally, we could also use our own frame format.

1. Is it possible to bypass the framing functionality in the nRF24L01+, allow us to insert our own sync word, FEC, etc.?

2. Is it possible to use an IRQ pin or monitor the TX FIFO fill level so we can continuously transmit and keep the FIFO full?

Has this been demonstrated by other customers before?

Hi,

1. You can not change the frame format other than the contents of CRC and ADDRESS.

2. You can use the interrupt that you get when you have transferred something, then feed new data into the FIFO.

The radio is not able to transmit at 100% duty cycle, the max transmit duration is 4 ms then you need to go back to standby before starting transmit again.

Best regards,

Øyvind
