Is there a simple way to check nrf24l01+ functionality?

Cannot get correct status value when trying to send data TX_DS not asserted

Hi Vic,

Have you verified you able to communicate with the nRF24L01+ ? for example, can write and read a register ? Do you use ACK and auto retransmit ? have you tried to follow Appendix A in the Product spec ?

Hi Vic, even if there is no Acknowledge, there will be MAX_RT IRQ returned.

I would suggest you to follow the example at Appendix A to see if you can catch the IRQ. Make sure you have set the IRQ pin on the MCU as input pin. CE must be triggered before the packet can be sent.
