UDP/TCP Widget

Send UDP/TCP packets with a widget on your home screen.

Makes sending UDP and TCP packets super easy but gives you tons of features and options!

The homescreen widget is ideal to remote-control any Arduino/microcontroller running an UDP or TCP server but of course you can connect to normal computers too.

Tested with Arduino, Raspberry Pi, ESP8266, Sonoff switches, SR-201 relays, IoT, embedded systems, µC, MCU, Netcat, Wireshark and more.

Or use it for network administration, diagnosis, white hat hacking or debugging your own programs.

🔌 The widget has different predefined designs and 130 icons. Combine them and choose their color or pick any image from your file system!

📡 Listen for a response/acknowledgement from the server and send the packet again on timeout. The number of attempts and the timeout is configurable.

📻 Show the server response in the widget. This could be something like a status text (e.g. ON changing to OFF).

🔌 Send UTF-8 or hexadecimal values

📡 The widget can open a message dialog each time if you want to send varying messages.

📻 Build-in local network scanner to find IP addresses quickly.

🔌 Different kinds of status notifications about the packets delivery.

📡 Setup a schedule to send packets automatically (experimental - works only on some devices)

📻 The app can listen to Android intents and act as an extension to other (automation) apps like Automate and Tasker. This means your phone can basically become an IoT hub in your pocket.

🔌Select text in any other app and use the share button to send text through this app quickly.

📡 Turn on WiFi automatically when ever you send a packet.

📻 Three payload terminators: Carriage Return, Line Feed, and an empty NULL byte to signal the recipient the end of the message.

🔌 Easy list management: add, move, delete and duplicate.

📡 The entire packet list with all its settings can be exported into an SQL database file. This can be edited simply on your PC, copied to a new device or used as a backup.

📻 The app can log all it's actions and sent/received packets for easier diagnosis.

🔌 All settings are explained in detail in the app!

Controlling your self-build smart home has never been so quick and easy!

It's free, so try it out!
