I'm trying to get two test sketches to work for the Nrf24l01 PA module with an arduino nano, but for some reason it will not work:
/* Tranmsitter code for the Arduino Radio control with PWM output
* Install the NRF24 library to your IDE
* Upload this code to the Arduino UNO, NANO, Pro mini (5V,16MHz)
* Connect a NRF24 module to it:
Module // Arduino UNO,NANO
GND -> GND
Vcc -> 3.3V
CE -> D9
CSN -> D10
CLK -> D13
MOSI -> D11
MISO -> D12
This code transmits 1 channels with data from pins A0 POTENTIOMETER

const uint64_t my_radio_pipe = 0xE8E8F0F0E1LL; //Remember that this code should be the same for the receiver
RF24 radio(9, 10);
// The sizeof this struct should not exceed 32 bytes
struct Data_to_be_sent {
byte ch1;
};
Data_to_be_sent sent_data;

{
radio.begin();
radio.setAutoAck(false);
radio.setDataRate(RF24_250KBPS);
radio.openWritingPipe(my_radio_pipe);
sent_data.ch1 = 127;
Serial.begin(9600);
}

this is what i get in the serial monitor of the transmitter:
