WebClient и MotionDetector останавливается через некоторое время

Я копал это около недели, и у меня нет никакого способа решить этот вопрос. Мой код Arduino работает некоторое время (несколько раз / несколько дней), а затем внезапно останавливается. Я пытаюсь реализовать WebClient в Arduino, который отправляет HTTP-запросы GET на какой-либо другой сервер каждый раз (периодически — каждые 90 секунд), когда обнаруживается движение / когда движение прекращается.

Ниже вы можете найти код. Кто-нибудь может помочь?

#include <Ethernet2.h>
#include <SPI.h>

byte mac[] = { 0x90, 0xA2, 0xDA, 0x10, 0x73, 0x88 };
IPAddress ip(192,168,20,84);
IPAddress server(192,168,50,93); // Google
IPAddress myDns(8, 8, 8, 8);

EthernetClient client;

//getMovement - sends a GET request when motion is detected
void getMovement() {
client.stop();
if (client.connect(server, 8080)) {
client.println("GET /GetARoomMaven/motion?roomId=1&movement=1");
client.println();
Serial.println("Movement Request Sent");
} else {
Serial.println("connection failed");
}
}
//getNoMovement - sends a GET request when motion had stopped
void getNoMovement() {
client.stop();
if (client.connect(server, 8080)) {
client.println("GET /GetARoomMaven/motion?roomId=1&movement=0");
client.println();
Serial.println("Movement Request Sent");
} else {
Serial.println("connection failed");
}
}
