how to send a struct larger than 32byte over nrf24l01 - nodemcu

Question

i have three nodemcu and I want to send a struct over nRF24l01+ , but my struct size is 52 byte and the nRf24l01+ module is just sending 32 byte !
how should I send my struct ?
my struct :
struct fullData{
unsigned long ttime;
String data1;
String data2;
String data3;
String data4;
}sndData,recData;
I tried this way but it dosen't work :
transmitter code:
void sendOverRadio(){
char data[sizeof(sndData)];
memcpy(data, &sndData, sizeof(sndData));
radio.stopListening();
int z = 0;
for(int i= 0 ; i<2 ; i++){
char dt[32];
dt[0] = i;
for(int j =1 ; j<32;j++){
dt[j]=data[z];
z +=1;
}
radio.write(&dt , sizeof(dt));
}
radio.startListening();
}
receiver code :
char data[sizeof(recData)];
void loop(){
if(radio.available()){
Serial.println("Radio Available...");
char dt[32];
while (radio.available()){
radio.read(&dt, sizeof(dt));
}
if(dt[0]==0){
memset(data, 0, sizeof(data));
memcpy(data, &dt[1], 32);
}else if(dt[0]==1){
memcpy(&data[32], &dt[1], 32);
memcpy(&recData, data, sizeof(recData));
}
}
}

RF24Network library handles payload splitting. Send your struct like this:
RF24NetworkHeader header(0, 'D');
if (!NETWORK.write(header, &sndData, sizeof(sndData))) {
Serial.println(F("Error."));
} else {
Serial.println(F("Success."));
}
