Hi, i was talking with the supplier and it seems that my board was faulty. He has sent a new one but i haven't received it yet.

Hi, thank you for your answer. I figured out that the wiring was the culprit, two pins were connected to each other because of a bad connection...

Hello, which pins did you connect? There is a lot of different configurations. Some say that with the Tx and Rx (and power of course) is enough.

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 |
Hello, thanks for your response. If you are using a ESP32 remember you have 3 serial ports to connect to. The new board just arrived from the manufacturer, let's hope I can make this one work lol.

[ 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

load:0x40078000,len:13964

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" ----
