surepic:
couldn't describe the whole schematic too much to write decide to upload image.
OK... that not how I wired up my arduino. this is your code that I ran (getting same issue as u)
#include <SoftwareSerial.h>
SoftwareSerial mySerial(10, 11); // RX, TX
//char string[] = "AT\r\n";
void setup() {
// Open serial communications and wait for port to open:
Serial.begin(115200);
while (!Serial) {
; // wait for serial port to connect. Needed for native USB port only
}
mySerial.begin(115200);
Serial.println("arduino");
mySerial.println("AT");
//delay(100);
//mySerial.write("AT");
Serial.println("Esp");
}
void loop() { // run over and over
while (mySerial.available()) {
Serial.write(mySerial.read());
}
}
your schematic does not really tell but how did you manage to print "mySerial.println("AT")" and "Serial.println("Esp")" to the SAME serial monitor when u tested the code? did you wire things differently then?
