Hi
I had purchased a LD2420 sensor
I had connected it to ESP32 as per the sketch shown in https://github.com/cyrixninja/LD2420. But I understand that my sensor is working only in ASCII mode and not in binary mode. Because of this
the existing libraries are not able to process the data. Also I understand that the firmware running on my sensor is Version 1.0.0.
Is there a way to upgrade the firmware to the latest version so that I can use this sensor and complete my design
Another problem is when I communicate with sensor using the following sketch
#define RX_PIN 16 // LD2420 TX -> ESP32 RX
#define TX_PIN 17 // LD2420 RX -> ESP32 TX
void setup() {
Serial.begin(115200);
Serial2.begin(115200, SERIAL_8N1, RX_PIN, TX_PIN);
}
void loop()
{
if (Serial2.available())
{
String line = Serial2.readStringUntil('\n');
line.trim();
Serial.println(line);
}
}
I see that sensor is always showing Human presence even when no human is around. Is there a way to resolve this problem
