Below is an example of how to use the BK-7670G TopSide with an Arduino UNO for serial communication:
// Example: Serial communication with BK-7670G TopSide
// Connect TX (Pin 3) of BK-7670G to RX (Pin 0) of Arduino UNO
// Connect RX (Pin 4) of BK-7670G to TX (Pin 1) of Arduino UNO
// Ensure VCC and GND are properly connected
void setup() {
Serial.begin(9600); // Initialize serial communication at 9600 baud
delay(1000); // Wait for the BK-7670G to initialize
Serial.println("BK-7670G TopSide is ready!"); // Send a test message
}
void loop() {
if (Serial.available()) {
String data = Serial.readString(); // Read incoming data from BK-7670G
Serial.print("Received: ");
Serial.println(data); // Print the received data
}
}
