I'd like to know the exact moment the Pluto SDR is transmitting or receiving, to avoid working with processing delays. How can I know the exact moment the Pluto SDR is transmitting or receiving? Is there a command or flag that activates at the exact moment of transmission or reception?

Hi,

On the RX side, when the buffer is created using iio_device_create_buffer or a refill is called using iio_buffer_refill, data is being acquired without any delay. On the TX side, whenever you call iio_buffer_push, data will be transmitted.
For what I understand, you would need a signaled event, but there is no way that I know of to do so with libiio.
