When can change to RX mode while a packet sent out?

When a packet sent out and get the TX_DS IRQ by nRF24l01+, the mode change to RX and read STATUS register then write the value to the STATUS register and write FLUSH_RX 0xff to get the RX IRQ for data receiving.But looks it affect the packet sending. So I want to know when can change to RX mode while a packet sent out? I would like to send 4 packets and receive 2 packets as quickly as possible continuously. Thanks.

  • Hi Pengyong,

    It's not very clear what your application does. Please give more information on:

    • Which chip you are using ?

    • Which protocol you are using ? ESB or use the radio directly ?

    • You are talking about PTX or PRX ?

    • "So I want to know when can change to RX mode while a packet sent out?" You mean you want to switch to RX even before TX finish ?

    In this figure, what exactly you want to change ?
