Posted by: admin - 04-12-2024, 06:37 AM - Forum: KC868-A32/A32 Pro - No Replies

Code:
void setup() {
  // put your setup code here, to run once:
Serial.begin(115200);
}

void loop() {
  // put your main code here, to run repeatedly:
Serial.print("Test with KinCony A32B Pro Serail");
}
make sure your setting as these image:
