🛜 Network – Your “Passport to the Internet”
What it is: Blocks for using Wi-Fi and connecting to networks.
What it does: Connects your project to Wi-Fi and the Internet.
Example: Connecting your robot to your home internet.
👉 It’s the robot’s personal router.
🧩 Fun Guide to Network Blocks (Clu-blocks Pro)
🌐 Important! Network blocks let your robot go online, send messages, and talk to other devices using Wi-Fi, TCP/UDP sockets, and even get the current time from the internet. It’s like giving your robot a passport to the digital world!
📶 Wi-Fi Setup & Info
| # | Block | What it does | Dropdown options | What the options mean |
|---|---|---|---|---|
| 1 | Connect Wi-Fi name "wifiname" password "wifipassword" |
Connects to a Wi-Fi network | — | Just like logging in to your home internet |
| 2 | Config Wi-Fi Set Wi-Fi mode to STA |
Sets Wi-Fi mode | STA, AP |
– STA: connects to a router– AP: becomes a hotspot |
| 3 | Activate Network Interface |
Turns Wi-Fi on or off | Activate, Deactivate |
Controls whether the robot’s Wi-Fi is active |
| 4 | Get Wi-Fi IP address |
Gets network info | IP address, subnet mask, Gateway, DNS |
Useful for debugging or displaying status |
| 5 | Get Wi-Fi Access Point Name |
Gets Wi-Fi name or channel | Access Point Name, Wi-Fi channel |
Shows current network name or channel number |
🔌 Socket Communication (TCP/UDP)
| # | Block | What it does | Dropdown options | What the options mean |
|---|---|---|---|---|
| 6 | Socket Init s Socket Type TCP |
Starts a socket connection | TCP, UDP |
TCP = reliable, UDP = fast |
| 7 | Bind to address initialize tuple ['0.0.0.0', 80] |
Sets up a server | — | Listens for incoming connections on port 80 |
| 8 | Send Socket initialize tuple ['127.0.0.1', 80] |
Sends data to a device | — | Sends to IP address and port |
| 9 | Socket Listen Socket TCP 5 |
Listens for connections | — | Waits for up to 5 devices to connect |
| 10 | Accept and return Socket |
Accepts a connection | — | Starts talking to a connected device |
| 11 | Socket Receive 1024 |
Receives data | — | Reads up to 1024 bytes of incoming info |
📤 TCP/UDP Data Transfer
| # | Block | What it does | Dropdown options | What the options mean |
|---|---|---|---|---|
| 12 | TCP Send transfer byte "Clu-Bots" |
Sends data over TCP | toInt, toFloat, transfer byte, bytetoInt |
Choose how to format the data |
| 13 | UDP Send transfer byte "Clu-Bots" |
Sends data over UDP | Same as above | Faster, but less reliable than TCP |
🕒 Network Time Protocol (NTP)
| # | Block | What it does | Dropdown options | What the options mean |
|---|---|---|---|---|
| 14 | Get network time(NTP) Server Address ntp.aliyun.com |
Gets the current time from the internet | ntp.aliyun.com, ntp1.aliyun.com, time1.cloud.tencent.com, etc. |
Choose a time server — great for syncing clocks or logs |
🧠 Quick Tips for Students
- Use Wi-Fi setup first — no internet, no networking!
- Use STA mode to connect to a router, or AP mode to create your own hotspot.
- Use TCP for reliable chat, UDP for fast messages — like games or sensors.
- Use NTP blocks to get the real-world time — perfect for timestamps or alarms.
- Always check IP and status before sending data — it helps avoid bugs!
