I can't send SMS with Lilygo TCALL SIM8OOL 1.4 version #212

Hello I have bought a lilygo TCALL SIM800L 1.4 version but the SMS send fonction doesn't work with the exemple on github. Does anyone have a solution ?

I have used this code :

// Please select the corresponding model

define SIM800L_IP5306_VERSION_20190610

//#define SIM800L_AXP192_VERSION_20200327 //#define SIM800C_AXP192_VERSION_20200609 //#define SIM800L_IP5306_VERSION_20200811

//const char simPIN[] = "1234";

// Define the serial console for debug prints, if needed

define DUMP_AT_COMMANDS

define TINY_GSM_DEBUG SerialMon

include "utilities.h"

// Set serial for debug console (to the Serial Monitor, default speed 115200)

define SerialMon Serial

// Set serial for AT commands (to the module)

define SerialAT Serial1

// Configure TinyGSM library

define TINY_GSM_MODEM_SIM800 // Modem is SIM800

define TINY_GSM_RX_BUFFER 1024 // Set RX buffer to 1Kb

include "TinyGsmClient.h"

ifdef DUMP_AT_COMMANDS

include "StreamDebugger.h"

StreamDebugger debugger(SerialAT, SerialMon); TinyGsm modem(debugger);

else

TinyGsm modem(SerialAT);

endif

// Set phone numbers, if you want to test SMS and Calls

define SMS_TARGET "+33"

void setup() { // Set console baud rate SerialMon.begin(115200);

delay(10);

// Start power management
if (setupPMU() == false) {
    Serial.println("Setting power error");
}

// Some start operations
setupModem();

// Set GSM module baud rate and UART pins
SerialAT.begin(115200, SERIAL_8N1, MODEM_RX, MODEM_TX);

delay(6000);
//if (strlen(simPIN) && modem.getSimStatus() != 3 ) {

// modem.simUnlock(simPIN); //} }

void loop() { // Restart takes quite some time // To skip it, call init() instead of restart() SerialMon.println("Initializing modem..."); modem.restart();

String modemInfo = modem.getModemInfo(); SerialMon.print("Modem: "); SerialMon.println(modemInfo);

delay(10000);

String imei = modem.getIMEI();
DBG("IMEI:", imei);

bool  res = modem.sendSMS(SMS_TARGET, String("Défaut de commande Digesteur 1 ") + imei);
DBG("SMS:", res ? "OK" : "fail");

// Do nothing forevermore
while (true) {
    modem.maintain();
}

}

Hi, you understood which are RX and TX pin connected between ESP32 and SIM800L?

amiiit commented 7 months ago

I have also bought what seems to be the same board and I have no success with the demo code.It seems like it has nothing to read from the SerialAT. I believe TX and RX should be set according to sketch attached to this issue, which is 26&27. Anyways, even flipping these didn't work.

I wonder, the gpio's 26&27 this refers to the ESP right, not to the SIM Module?

Does anyone have a working example for this board? It seems to be like a weird mix of v1.4 PCB, but with the old SIM800L module, perhaps this messed up the wiring?

it's my working code for ESPHOME:

esphome: name: combinatoregsm

ota: safe_mode: true

wifi: ssid: !secret wifi_ssid password: !secret wifi_password

esp32: board: esp32dev framework: type: arduino

Enable logging

logger:

level: DEBUG

baud_rate: 0 # disable uart logger on esp 8266

Enable Home Assistant API

api: services:

text_sensor:

binary_sensor:

uart:

debug:

baud_rate: 9600 tx_pin: 27 rx_pin: 26

switch:

I don't know the details but this setup function solved my problem: 

void setup()
{
    SerialMon.begin(9600);

    delay(10);

    if (setupPMU() == false) {
        Serial.println("Setting power error");
    }
    setupModem();

    SerialAT.begin(115200, SERIAL_8N1, MODEM_RX, MODEM_TX);

    SerialMon.println("Initializing modem...");
    modem.restart();

    delay(10000);

    SerialAT.println("AT+CSMP=17,167,0,8"); 
    updateSerial();
    delay(500);

    String imei = modem.getIMEI();
    DBG("IMEI:", imei);

    bool  res = modem.sendSMS(SMS_TARGET, String("Hello") + imei);
    DBG("SMS:", res ? "OK" : "fail");
}

The key line is : SerialAT.println("AT+CSMP=17,167,0,8"); Apparently it should be the default but with some network providers you need to send it again.

@ArashIranfar i have the same probleme, can you give the code of updateSerial() please ? is it personal code or somthing coming from utilities.h ?

Best Regards

ArashIranfar commented 3 months ago

I made no changes to the updateSerial() function. It is the normal one you see in every Sim800 example:

void updateSerial(){ while (Serial.available()){ SerialAT.write(Serial.read());//Forward what Serial received to Software Serial Port } while (SerialAT.available()){ Serial.write(SerialAT.read());//Forward what Software Serial received to Serial Port } }

Also check the local forums to see if the module is compatible with your local service provider. In my region there are 3 SPs and only one requires the following line:

SerialAT.println("AT+CSMP=17,167,0,8");
