esb_flush_tx()

int esb_flush_tx

(

void

)

#include <include/esb.h>

Flush the TX buffer.

This function clears the TX FIFO buffer.

Note

The radio must not be in transmission state for this operation to succeed. This requirement prevents erroneous operations on the FIFO queue that could occur if the buffer is cleared while the radio is transmitting.

Return values

0	If successful (FIFO cleared).
-EACCES	If ESB is not initialized.
-EBUSY	If radio is transmitting.
