[ x] I have read the Troubleshooting section of the ReadMe

What type of issues is this?

[ x] Request to support a new module

[ ] Bug or problem compiling the library
[ ] Bug or issue with library functionality (ie, sending data over TCP/IP)
[ ] Question or request for help

What are you working with?

Modem: SIMCOM SIM7600SA
Main processor board: ESP32
TinyGSM version: (0.11.7)
Code:
#define TINY_GSM_MODEM_SIM7600

#define SerialMon Serial

// Set serial for AT commands (to the module)
#define SerialAT Serial1

// #define TINY_GSM_DEBUG SerialMon

#include <TinyGsmClient.h>

// Module baud rate
uint32_t rate = 115200; // Set to 0 for Auto-Detect

void setup() {
Serial.print("Setup comenzando");
// Set console baud rate
SerialMon.begin(115200);
delay(6000);
}

void loop() {

if (!rate) {
SerialMon.println(F(""));
SerialMon.println(F(" Module does not respond!"));
SerialMon.println(F(" Check your Serial wiring"));
SerialMon.println(F(" Check the module is correctly powered and turned on"));
SerialMon.println(F(""));
delay(30000L);
return;
}

SerialAT.begin(rate, 18, 19);

// Access AT commands from Serial Monitor
SerialMon.println(F(""));
SerialMon.println(F(" You can now send AT commands"));
SerialMon.println(F(" Enter "AT" (without quotes), and you should see "OK""));
SerialMon.println(F(" If it doesn't work, select "Both NL & CR" in Serial Monitor"));
SerialMon.println(F(""));

while(true) {
if (SerialAT.available()) {
SerialMon.write(SerialAT.read());
}
if (SerialMon.available()) {
SerialAT.write(SerialMon.read());
}
delay(0);
}
}

Scenario, steps to reproduce

I'm trying to run the simple AT_Debug code and i'm unable to stablish connection to the module. I've tried everything that could make it work and no result so i'm assuming it's a compatibility issue.

Expected result

Make the code work

Actual result

You might have seen that these lines:
if (!rate) {
rate = TinyGsmAutoBaud(SerialAT);
}
Are missing from the code. This is because it crashes my program. The output is:

ets Jul 29 2019 12:21:46

rst:0x8 (TG1WDT_SYS_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
configsip: 0, SPIWP:0xee
clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00
mode:DIO, clock div:1
load:0x3fff0030,len:1344
load:0x40078000,len:13964
load:0x40080400,len:3600
entry 0x400805f0

Debug and AT command log

You can now send AT commands
Enter "AT" (without quotes), and you should see "OK"
If it doesn't work, select "Both NL & CR" in Serial Monitor

---- Sent utf8 encoded message: "AT" ----

Hi, I first connect the RX and TX of the modem to UART0, which I figured out later was a bad idea because of the intrinsic functions of the UART0
