+# Kobuki automatische reconnect
+
+Mijn taak was om de kobuki automatisch te reconnecten als de verbinding verbroken werd met de pi. nu moet je telkens handmatig de pi laten connecten met de kobuki, dit is niet handig als iemand niet weet hoe dit moet. 
+
+De connectie word gemaakt met ttyUSB0. Dat is de eerste poort die wij kunnen gebruiken voor de kobuki. 
+
+```cpp
+  robot.startCommunication("/dev/ttyUSB0", true, null_ptr);
+```
+
+ik heb een functie gemaakt die kijkt of de pi nog is verbonden aan de kobuki. in de if statement kijkt hij elke 5 seconden of de ttyusb0 poort beschikbaar is. 
+
+```cpp
+void checkKobukiConnection()
+{
+    while (true)
+    {
+        std::lock_guard<std::mutex> lock(connectionMutex);
+
+        // Controleer of het apparaat beschikbaar is
+        if (!std::ifstream("/dev/ttyUSB0")){
+            if (kobuki_connected){
+                cout << "Kobuki disconnected: USB device not found." << endl;
+                kobuki_connected = false;
+            }
+            std::this_thread::sleep_for(std::chrono::seconds(5));
+            continue; // Probeer later opnieuw
+        }
+```	
+
+Hier kijk ik dan of de kobuki is geconnect, zoniet dan moet ie weer connecten met ttyUSB0
+
+```cpp
+ // Controleer of de Kobuki verbonden is
+        if (!robot.isConnected()){
+            if (kobuki_connected){
+                cout << "Kobuki disconnected." << endl;
+                kobuki_connected = false;
+            }
+
+            cout << "Attempting to reconnect Kobuki..." << endl;
+            robot.startCommunication("/dev/ttyUSB0", true, nullptr);
+
+            if (robot.isConnected()){
+                cout << "Kobuki reconnected successfully!" << endl;
+                kobuki_connected = true;
+            }
+            else{
+                cout << "Failed to reconnect Kobuki, retrying in 5 seconds..." << endl;
+            }
+        }
+```        
+
+Nu heb ik het probleem dat als ik de kabel eruit steek en terug in de kobuki stop dat de pi niet meer wil connecten. Dit komt omdat het systeem denkt dat de poort "ttyUSB0" nog steeds gebruikt word. Als ik de kabel dan terug stop word de poort "ttyUSB1" gebruikt, omdat ttyusb0 niet word vrijgegeven.
