a6esp32's Issues

cant connect to module

Hi, i need some help...
I'm trying to use the A6 gsm module to receive SMS and show them on an LCD screen, but i cant connect to the A6 module using your library. The board i'm using is the HW-549. I have connected the regulator enable pin as my "power switch", since there is no reset pin available to the user (without soldering to the chip itself). The module is connected to the UART2 port of the ESP-WROOM-32. Here is my code:

#include <stdio.h>
#include <Arduino.h>
#include <Wire.h>
#include <LiquidCrystal_PCF8574.h>
#include <A6ESP32.h>

#define A6pow 4
#define RX 16
#define TX 17
#define UART 2

LiquidCrystal_PCF8574 lcd(0x27); // Clase del LCD con parametros para 16x2
A6ESP32 A6l(UART);

void lcdSetup();
void welcome();
void a6Setup();
void a6Fail();

void setup() {
  // put your setup code here, to run once:
  Serial.begin(115200);
  lcdSetup();

  welcome();
  a6Setup();
}

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

void lcdSetup(){
  char error = 0;
  Wire.begin();
  Wire.beginTransmission(0x27);
  error = Wire.endTransmission();
  Serial.printf("Error: %d", error);

  if (error == 0) {
    Serial.println(": LCD found.");
    lcd.begin(16, 2);  // initialize the lcd

  } else {
    Serial.println(": LCD not found.");
  }
}

void welcome(){
  lcd.clear();
  lcd.home();
  lcd.setBacklight(255);
  lcd.print(" INIC.  CENTRAL");
  lcd.setCursor(0, 1);
  lcd.print("     ESPERE");
}

void a6Setup(){
  Serial.println("INICIANDO MODULO A6");
  A6l.powerCycle(A6pow);
  if(A6l.begin(115200, RX, TX) != A6_OK){
    a6Fail();
  }
  Serial.println("MODULO A6 INICIADO");
  Serial.printf("RSSI: %s\n\r", A6l.getSignalStrength());


}

void a6Fail(){
  Serial.println("FALLA MODULO A6");
  while(1){
      lcd.setCursor(0,1);
      lcd.print("FALLA MODULO A6");
      delay(1000);
      lcd.setCursor(0,1);
      lcd.print("               ");
      delay(1000);
    }
}

I've enabled the debug define to see if i could get any useful information:

Error: 0: LCD found.
INICIANDO MODULO A6
Power-cycling module...
Done, waiting for the module to initialize...
Done.
Command:

Timed out.Command:

Timed out.FALLA MODULO A6

And I also had to add this to the .h file:

#ifndef max
#define max(a,b) (((a) > (b)) ? (a) : (b))
#endif

otherwise it would give me errors at compile time:
