Serial Receive Not Working With DMDESP & ESP8266

[akshaythoke9116]

Hi All,
I want to receive the data from serial and display on P10 Display
following code for the Receiving Code, but i am not getting the data.

void loop(){
server.handleClient(); //--> Handle client requests
Disp.loop(); //--> Run "Disp.loop" to refresh the LED
if(Serial.available())
{
char ch=Serial.read();
Serial.println(ch);
recieved_data=Serial.readString();
Serial.println(recieved_data);
}
main_display();
