isPVariant returning false for a actual P variant chip.

[sundariitm]

Hello,

if(radio.isPVariant()) {
Serial.println("Radio is nRF24L01 plus variant");
}
else {
Serial.println("Radio is nRF24L01 NON-plus variant");
}

per documentation for a non-P device radio.setDataRate(RF24_250KBPS) should fail and IS failing..

The marking on the chip is as per datasheet and indicates P variant.

thx

actually its not correct , I tested
nrf24l01 (non-p version) can't config 250Kbps but you can set bit 5 in RF_SETUP register,
so that isn't good way to know what is nrf24 version
