Boas pessoal,
Já alguém encontrou algum exemplo para envio de ficheiros entre nRF24L01? Já pesquisei e aparece pouca coisa.
O ficheiro a enviar seria do tipo *.WAV . Nas minhas pesquisas encontrei uma coisa semelhante para ethernet. Deverá ser adaptável com alguma ajuda 
// Wave format file transfer demo for Arduino Mega over Ethernet
// Author: Bruno Senzio-Savino Barzellato
// V 1.0
// Notes: Transfer function can be optimized for filename and buffer size input
// December 1, 2016
// So far no data for this, decided to upload it for people that might consider this
// useful :)
//Using SdFat library

#include <Ethernet2.h>
// SD chip select pin
const uint8_t chipSelect = 53; //Connect SD Card to pins 50, 51, 52 and 53
// Enter a MAC address for your controller below.
// Newer Ethernet shields have a MAC address printed on a sticker on the shield
byte mac[] = { 0x90, 0xA2, 0xDA, 0x10,0xCA,0x90 };
IPAddress server(10, 10, 6, 93); //SERVER IP ADDRESS
// Set the static IP address to use if the DHCP fails to assign

// with the IP address and port of the server
