Boa tarde pretendo enviar texto do arduino para o raspberry sem ser escrito logo no programa mas sim quando abro a consola do arduino, onde escrevo e depois faço enviar, a comunicação está feita com NRF24L01, aqui deixo o código que tenho até agora que está a transmitir o texto logo em loop e eu queria enviar palavra a palavra por exemplo.

Arduino

#include <SPI.h>
#include <nRF24L01.h>
#include <printf.h>
#include <RF24.h>
#include <RF24_config.h>
#include <Wire.h>

RF24 radio(9, 10);

void setup()
{
radio.begin();
radio.setPALevel(RF24_PA_MAX);
radio.setChannel(0x76);
radio.openWritingPipe(0xF0F0F0F0E1LL);
radio.enableDynamicPayloads();
radio.powerUp();
radio.disableCRC();

Serial.begin(9600);
while (!Serial) {;}// On attend que le port série soit disponible

Wire.begin();
delay(100); // Active le bus I2C
// Initialise les variables

}

void loop()

{
const char text[] = "Envio de Dados para raspberry:";
radio.write(&text, sizeof(text));
delay(5000);
}

Raspberry

radio = NRF24(GPIO, spidev.SpiDev())
radio.begin(0, 17)

radio.setPayloadSize(32)

radio.startListening()

while(1):
# ackPL = [1]
while not radio.available(0):
time.sleep(1 / 100)
receivedMessage = []
radio.read(receivedMessage, radio.getDynamicPayloadSize())
print("Received: {}".format(receivedMessage))

print("Translating the receivedMessage into unicode characters")
string = ""
for n in receivedMessage:
# Decode into standard unicode set
if (n >= 32 and n <= 126):
string += chr(n)
print("Out received message decodes to: {}".format(string))
