Provade faktiskt en fuling då en kollega tipsat som jag skulle prova.

ställde frågan såhär
i want c code for initialsing module and sending sms with mikroE module 4G LTE 2 Click - voice which has LARA-R6001 from u-blox
fick svaret
To initialize the MikroE 4G LTE 2 Click module (which uses the LARA-R6001 module from u-blox) and send an SMS in C, you’ll need to interact with the module through AT commands via a UART or SPI interface, depending on how the module is connected to your system. Below is a general framework for how to write the code to initialize the module and send an SMS.
Key steps:
Initialize the UART or SPI interface (based on your hardware setup).
Send AT commands to the module to initialize it (e.g., setting up the module, checking network registration).
Send the AT command to send an SMS.
Below is an example of C code that could be used on an embedded system (like using an STM32, Arduino, or other microcontroller) to interact with the MikroE LTE module:
Kod: Markera allt
#include <stdio.h>
#include <string.h>
#include "uart.h" // Assuming you have a UART driver library for your platform
// AT Command timeout in milliseconds
#define AT_COMMAND_TIMEOUT 2000
// Send AT command function
int sendATCommand(char *cmd, char *response, int timeout) {
uart_write(cmd); // Write the AT command to the module
uart_write("\r\n");
int bytesRead = uart_read(response, 256, timeout); // Read the response from the module
if (bytesRead > 0) {
return 1; // Success
} else {
return 0; // Timeout or failure
}
}
// Function to initialize the 4G LTE module
int init4GLTEModule() {
char response[256];
// Reset the module
if (!sendATCommand("AT+CSQ", response, AT_COMMAND_TIMEOUT)) {
printf("Error: No response from the module\n");
return 0;
}
// Check the module version (optional, to verify communication)
if (!sendATCommand("ATI", response, AT_COMMAND_TIMEOUT)) {
printf("Error: Failed to get module information\n");
return 0;
}
printf("Module Info: %s\n", response);
// Set SMS mode to text mode
if (!sendATCommand("AT+CMGF=1", response, AT_COMMAND_TIMEOUT)) {
printf("Error: Failed to set SMS text mode\n");
return 0;
}
// Check network registration
if (!sendATCommand("AT+CREG?", response, AT_COMMAND_TIMEOUT)) {
printf("Error: No network registration\n");
return 0;
}
return 1; // Module initialized successfully
}
// Function to send an SMS
int sendSMS(const char *phoneNumber, const char *message) {
char command[256];
char response[256];
// AT command to send an SMS
snprintf(command, sizeof(command), "AT+CMGS=\"%s\"", phoneNumber);
// Send the AT command to the module
if (!sendATCommand(command, response, AT_COMMAND_TIMEOUT)) {
printf("Error: Failed to send SMS command\n");
return 0;
}
// Send the message text
uart_write(message);
uart_write("\r\n");
// Send the end of message (Ctrl+Z, 0x1A in ASCII)
uart_write("\x1A");
// Wait for the response from the module
if (!sendATCommand("", response, AT_COMMAND_TIMEOUT)) {
printf("Error: Failed to send SMS\n");
return 0;
}
printf("SMS sent successfully\n");
return 1;
}
int main() {
// Initialize UART communication
uart_init(9600); // Assuming 9600 baud rate for the UART communication
// Initialize the 4G LTE module
if (!init4GLTEModule()) {
printf("Error: LTE Module initialization failed\n");
return -1;
}
// Send SMS
const char *phoneNumber = "+1234567890"; // Replace with the recipient's phone number
const char *message = "Hello from 4G LTE module!";
if (!sendSMS(phoneNumber, message)) {
printf("Error: SMS sending failed\n");
return -1;
}
return 0;
}
