#79739 Hi :). I need some help , I can´t find any tutorial about this topic. I need to connect my ESP8266 with GSM module SIM800L + I would like to code in Arduino IDE (I saw one tutorial in Lua but i dont want to learn new language) . when I try this code
Code: Select all#include <SoftwareSerial.h>

String Arsp, Grsp;
SoftwareSerial gsm(10, 11); // RX, TX

void setup() {
  // put your setup code here, to run once:

  Serial.println("Testing GSM SIM800L");


void loop() {
  // put your main code here, to run repeatedly:

    Grsp = gsm.readString();

    Arsp = Serial.readString();

, serial monitor writes lot of symbols over and over : "⸮ ⸮@⸮B??" .... Module is powered by battery and they are connected through RX TX pins. So is it possible? Please help.
