PySerial library (for serial communication)Code
```python
import serial# Open serial connection to the multimeter
ser = serial.Serial('COM3', 9600, timeout=1) # Replace COM3 with your serial port# Set the multimeter to measure voltage (DC)
ser.write(b'VOLT_DC
')# Read and print the measurement result
response = ser.readline().decode().strip()
print(f'Voltage (DC): {response} V')# Set the multimeter to measure current (DC)
ser.write(b'CURR_DC
')# Read and print the measurement result
response = ser.readline().decode().strip()
print(f'Current (DC): {response} A')# Close the serial connection
ser.close()

#include <iostream>
#include <BluetoothAPI.h>int main() {
// Initialize Bluetooth connection to the multimeter
BluetoothDevice device = BluetoothDiscover("V830A Multimeter");
if (!device.isValid()) {
std::cerr << "Failed to connect to the multimeter." << std::endl;
return 1;
}// Set the multimeter to measure resistance
std::string command = "RESIST
";
device.send(command);// Read and print the measurement result
std::string response = device.receive();
std::cout << "Resistance: " << response << " " << std::endl;// Close the Bluetooth connection
