Я сейчас тоже подобное делаю, тоже новичек, АТ командами пока делаю, отправляю с Ардуино команду на ЕСП по софтсериал, а по сериал приходит как то криво, тип так
Код:

код которым отправляю принимаю
Код:
#include <SoftwareSerial.h>
SoftwareSerial mySerial(10, 11); // RX, TX
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
}
//Serial.println("Goodnight moon!");
// set the data rate for the SoftwareSerial port
mySerial.begin(115200);
//mySerial.print("AT+GMR\r\n");
}
void loop() { // run over and over
if (mySerial.available()) {
Serial.write(mySerial.read());
}
if (Serial.available()) {
mySerial.write(Serial.read());
}
}
