CP2102 MQTT-Client

Network topology

For room 1041 we used

• FritzBox from the server rack
• Extra Fritz Box so we can configure WiFi and observe clients/traffic
• Cables to connect administrators and clients
• For visualization of the config see the packet tracer file ff68e296

Tips & Tricks

• You can set static IP's so you don't have to update the ip configuration for Client/Broker every time you restart them

TODO [ ] Try configuring with devices not in the same Network
