SIM7600E AT command transparently transmitted to ESP32 Arduino code and BIN firmware

[admin]

function: Use KinCony G1 module to transparently transmit AT commands of SIM7600 4G module to gpio13 and gpio14 of esp23-s3. So that KinCony Controller can connect with extend G1 4G module by KCS v3 firmware.
   
   
   

Code:

#include <HardwareSerial.h>

// Define hardware serial ports
HardwareSerial SimSerial(1);     // Use hardware serial port 1 (GPIO9 and GPIO10)
HardwareSerial ExtendSerial(2);  // Use hardware serial port 2 (GPIO13 and GPIO14)

void setup() {
  // Initialize the extended serial port (hardware serial port 2)
  ExtendSerial.begin(115200, SERIAL_8N1, 13, 14); // RX=GPIO13, TX=GPIO14
  while (!ExtendSerial) {
    ; // Wait for the extended serial port to connect
  }

  // Initialize the SIM7600 serial port (hardware serial port 1)
  SimSerial.begin(115200, SERIAL_8N1, 9, 10); // RX=GPIO9, TX=GPIO10
}

void loop() {
  // If data is received from the extended serial port, forward it to the SIM7600 module
  if (ExtendSerial.available()) {
    while (ExtendSerial.available()) {
      char data = ExtendSerial.read();
      SimSerial.write(data);
    }
  }

  // If data is received from the SIM7600 module, forward it to the extended serial port
  if (SimSerial.available()) {
    while (SimSerial.available()) {
      char data = SimSerial.read();
      ExtendSerial.write(data);
    }
  }
}
