which addresses sould be kept in Transmitter and Receiver side ? could you please explain with some example as i am not able to understand...

Please help

Thanks

Hi,

You set which role the nRF24L01+ has in the CONFIG register, bit 0 (field called "PRIM_RX"). This controls if the device is a Primary Receiver (PRX) or a Primary Transmitter (PTX).

All the other configurations can be left untouched for a simple functional test. Now you can upload payloads (3 bytes length by default) to the FIFO. When you then pulse pin "CE" for >10us, the radio will start to transmit the payload over-the-air.

Check out the "nRFgo SDK" (enhanched_shockburst_examples) if you want to see the flow: www.nordicsemi.com/.../nRFgo-SDK

It's written for our nRF24L-series SoC-parts, but the radio interface is basically the same.

Best regards Håkon
