Communication between two hc 05 Bluetooth modules not working - arduino

Question

I Have a problem with the connection between two hc 05 modules. The bluetooth modules are paired using AT commands. But when I run the code I cant get any data from the reciever. The bluetooth modules blink together but no data is displayed in the reciever. This is for a RC car that is controlled by a remote controller.
This is the code for the remote
void setup() {
pinMode(A6, INPUT);
pinMode(A5, INPUT);
pinMode(A4, INPUT);
pinMode(A2, INPUT);
pinMode(3, INPUT_PULLUP);
pinMode(4, INPUT_PULLUP);
pinMode(5, INPUT_PULLUP);
Serial.begin(38400);
}
void loop() {
int rud = analogRead(A6);
int rlr = analogRead(A5);
int lud = analogRead(A4);
int llr = analogRead(A3);
int led = digitalRead(3);
int obs = digitalRead(4);
int line = digitalRead(5);
Serial.println(lud);
Serial.println(llr);
Serial.println(led);
Serial.println(obs);
Serial.println(line);
Serial.print("\n");
if (lud <= 50) {
Serial.write('2');
delay(500);
}
else if (lud >= 950) {
Serial.write('1');
delay(500);
}
else if (llr <= 50) {
Serial.write('3');
delay(500);
}
else if (llr >= 950) {
Serial.write('4');
delay(500);
}
else if (led == 0) {
Serial.write('6');
delay(500);
}
else if (obs == 0) {
Serial.write('7');
delay(500);
}
else if (line == 0) {
Serial.write('8');
delay(500);
}
else if (llr > 50 && llr < 950 && lud > 50 && lud < 950){
Serial.write('5');
delay(500);
}
}
I have made sure all the baudrates are 38400 and when I just type the numbers in the serial monitor of the reciver it works fine. I have switched the bluetooth modules but It didn't work either. Boath remote and car has TX - RX and RX - TX wiring.
This is the code of the reciever
int fl = 9;
int fr = 10;
int bl = 11;
int br = 12;
int Max = 255;
char data = 0;
void setup() {
pinMode(fl, OUTPUT);
pinMode(fr, OUTPUT);
pinMode(bl, OUTPUT);
pinMode(br, OUTPUT);
Serial.begin(38400);
}
void forword() {
Serial.println("Foword");
analogWrite(fl, Max);
analogWrite(fr, 0);
analogWrite(bl, Max);
analogWrite(br, 0);
}
void backword() {
Serial.println("Backword");
analogWrite(fl, 0);
analogWrite(fr, Max);
analogWrite(bl, 0);
analogWrite(br, Max);
}
void left() {
Serial.println("Left");
analogWrite(fl, 0);
analogWrite(fr, Max);
analogWrite(bl, Max);
analogWrite(br, 0);
}
void right() {
Serial.println("Right");
analogWrite(fl, Max);
analogWrite(fr, 0);
analogWrite(bl, 0);
analogWrite(br, Max);
}
void Stop() {
Serial.println("Stop");
analogWrite(fl, 0);
analogWrite(fr, 0);
analogWrite(bl, 0);
analogWrite(br, 0);
}
void loop() {
if (Serial.available() > 0) {
data = Serial.read();
if (data == '1') {
forword();
}
else if (data == '2') {
backword();
}
else if (data == '3') {
right();
}
else if (data == '4') {
left();
}
else if (data == '5') {
Stop();
}}
}
I used softwere serial as well but It gave me the same result. The reciever is an arduino mega and the transmitter is an arduino nano
Pls help.
Thank you.
I have made sure all the valtages are correct and I have made a robot like this before and it worked but I just can't find what's wrong. I expect it to send data to the receiver with out any noise.
