Send and Receive SMS Messages

Send English Messages

1. Set the local SMS message center: AT+CSCA="+8613800755500" + Enter; return OK. <br>
2. AT+CMGF=1: Set the SMS mode as TEXT;<br>
3. AT+CMGS="phone number" <Enter>, set the receiver phone number, and then return: ">"; Send the required message, such as "Send message test!", and Enter is not needed at the end. After editing the message, send it in hexadecimal format with the key value of 1A for sending (1A represents "CTRL+Z" and is used to indicate the module to execute the send operation, alternatively 1B (1B represents "ESC") can be sent to cancel the operation). After successful transmission, the module returns "+CMGS: 15" to confirm successful sending, as shown in the figure below.<br>

Receive English Messages

1. Send a message "This is a receive test for SIM7600X!" on your phone to the test module.
2. When receiving a message, the serial port will automatically report the information. For example, "SM", 20, indicates that there are 20 messages in the Short Message (SM) storage. The message just sent is the 20th message.
3. Read the message: AT+CMGR=20 reads the 20th message (AT+CMGL="ALL" is for reading all messages).
4. Delete the message: AT+CMGD=20 as shown below:
5. Convert the displayed message to text through the code converter.

TTS (Text-to-Speech)

The commonly used commands for TTS (Text-to-Speech) are as follows:

AT+CTTSPARAM=? // View the range of adjustable parameters
AT+CTTSPARAM=1,3,0,1,1 // Set parameters
AT+CTTSPARAM? // Read the current TTS settings
AT+CTTS=1,"6B228FCE4F7F75288BED97F3540862107CFB7EDF" // Synthesize and play UCS2 text
AT+CTTS=2,"1234567890" // Synthesize and play text

LBS

The common commands for LBS (Location-Based Service) base station positioning functionality are as follows:

AT+CLBS=? // View the range of parameters that can be set
AT+SIMEI=xxxxx // If there is no IMEI, set the IMEI first; xxxxx must correspond to the IMEI code on the module sticker
AT+CLBS=2 // Retrieve detailed address
AT+CLBS=1 // Retrieve current latitude and longitude

Demo Description

ESP32-S3 Application

Camera

This demo is based on the CameraWebServer demo of the ESP32.

• Firstly, you need to set the WiFi name and password and switch the hardware to ESP32S3 by default.
• Please turn on the CAM of the DIP switch on the back of the development board, and connect to the supported cameras.
• Please check CameraPins:

#define PWDN_GPIO_NUM     -1
#define RESET_GPIO_NUM    -1
#define XCLK_GPIO_NUM     34
#define SIOD_GPIO_NUM     15
#define SIOC_GPIO_NUM     16
#define Y9_GPIO_NUM       14
#define Y8_GPIO_NUM       13
#define Y7_GPIO_NUM       12
#define Y6_GPIO_NUM       11
#define Y5_GPIO_NUM       10
#define Y4_GPIO_NUM       9
#define Y3_GPIO_NUM       8
#define Y2_GPIO_NUM       7
#define VSYNC_GPIO_NUM    36
#define HREF_GPIO_NUM     35
#define PCLK_GPIO_NUM     37

• Burn the code and open the terminal to access the prompted IP:

TF-Card

• Insert the TF-Card into the TF card slot.
• Pinout definition:

const int SDMMC_CLK = 5;
const int SDMMC_CMD = 4;
const int SDMMC_DATA = 6;
const int SD_CD_PIN = 46;

• Program the demo, and open the terminal to display the file content:

RGB

Onboard a WS2812b RGB LED, and the signal pin is 38.
After programming the sample demo, the LED light is expected to display a gradient color.

BAT

This development board utilizes the MAX17048 as the battery charge measurement IC.

• First, confirm the I2C pin.

• Program the code and change the threshold:

Portable WIFI Demo

• This demo uses the TinyUSB protocol stack to communicate with a 4G Cat-1 module, using ppp dial-up to provide the network to the ESP32-S3.
• This demo uses the compiled firmware, please download Flash Tools first.

• Download the firmware:
  • ESP32-S3-A7670E_USB_4G_CDC.bin
  • ESP32-S3-SIM7670G_USB_4G_CDC.bin
• Open the Flash Tools, select the development mode, choose the firmware, with the address set to "0x0", as shown in the diagram, and insert the SIM card to download and start the program.

• The back of the development board toggle switch 4G on, USB off, re-power on the development board, wait for the LED display red, open the phone to connect to WIFI: ESP32-S3-A-SIM7670X-4G-HAT, password: 12345678 to access the Internet.

• For more details, you can refer to sample demo.

Waveshare Cloud Application

Please download the demo, and open the GNSS-With-WaveshareCloud sample demo.
In this application, communication between ESP32-S3 and A7670E-FASE is established using ESP32-S3's software serial port. By sending AT commands, the GNSS (Global Navigation Satellite System) is activated, and NMEA GNSS data is parsed and uploaded to the Waveshare Cloud. The specific location of the development board is then displayed on a web view map page.

Here, we take the map service provided by Waveshare Cloud as an example:
1. Through Device|Attributeto create any devices, and obtain the MQTT connection data.

2. Enter the parameters in the GNSS-With-WaveshareCloud demo.
