RF24 Library: Driver for nRF24L01(+) 2.4GHz Wireless Transceiver

Using Arduino Networking, Protocols, and Devices

I wonder this, if I do this in code:

radio.begin();
radio.setRetries(15,15);
radio.setPALevel(RF24_PA_LOW);
radio.setDataRate(RF24_250KBPS);
radio.setPayloadSize(10);
radio.setChannel(10);
radio.setAutoAck(true);
radio.printDetails();

It's still showing this when I look status of module:
Data Rate = 1MBPS
Model = nRF24L01
CRC Length = 16 bits
PA Power = PA_HIGH

Should radio.setDataRate(RF24_250KBPS); affect immediately?
