ASCII of integer to integer in Arduino - arduino

Question

I am working on a project with LoRa and Arduino and I am facing a weird issue where when I transmit a integer the receiver receives at ASCII value which is not good at my case because I wanted to transmit sensor data(3 digits) which is not possible by ASCII. I will also attach my code(converted into a basic integer code for testing) I need a Solution to fix this BTW I am using Arduino UNO for transmitting and Arduino Mega for receiving and SX1278 LoRa Module for both transmitting and receiving.
Transmitter Code(Arduino UNO):
#include <SPI.h>
#include <LoRa.h>
int val = 5;
void setup() {
Serial.begin(9600);
while (!Serial);
Serial.println("LoRa Sender");
if (!LoRa.begin(433E6)) {
Serial.println("Starting LoRa failed!");
while (1);
}
}
void loop() {
Serial.print("Sending packet: ");
// send packet
LoRa.beginPacket();
LoRa.print(val);
LoRa.endPacket();
delay(500);
}
Receiver Code(Arduino Mega):
#include <SPI.h>
#include <LoRa.h>
#define LORA_SS 53
#define LORA_RST 9
#define LORA_DIO0 8
int val;
void setup() {
pinMode(LORA_SS, OUTPUT);
digitalWrite(LORA_SS, HIGH);
LoRa.setPins(LORA_SS, LORA_RST, LORA_DIO0);
Serial.begin(9600);
while (!Serial);
Serial.println("LoRa Receiver");
if (!LoRa.begin(433E6)) {
Serial.println("Starting LoRa failed!");
while (1);
}
}
void loop() {
// try to parse packet
int packetSize = LoRa.parsePacket();
if (packetSize) {
// received a packet
Serial.print("Received packet '");
// read packet
while (LoRa.available()) {
//Serial.print((char)LoRa.read());
int val = LoRa.read();
}
Serial.print(val);
// print RSSI of packet
Serial.print("' with RSSI ");
Serial.println(LoRa.packetRssi());
}
}
Output of the receiver :
Received packet '53' with RSSI -5

Answer 1

To Fix this issue just send the value as an integer, since LoRa receives as char/string same it in a string variable in the receiver and convert it into integer with toInt(); and that will fix it!
