NRF24L01 communication link

I am using two numbers of NRF24L01 for RF communication for my meter project. taking one NRF as transmitter and another one as receiver. But i want to know how to communicate the both. how to tune it . how to send and receive data. Pls do explain me and send me the details.

Thank u.

program it using SPI port, look at this link: http://gpio.kaltpost.de/?page_id=726
search for nrf24l01 (or nrf24l01P) product specification, there would be commands
For example, from datasheet: "06 RF_SETUP RF Setup Register". You can write to this register using something like SPI_WR_Reg(0x20 + 0x06, 0x00 <-your config bits here);
