WE vs UDP TCP Sender & Receiver

This app demonstrates the capabilities of a Bluetooth LE and Sensor gadget that is provided from Würth Elektronik eiSos for the Wireless Connectivity Seminars. A Bluetooth LE connection can be build up from Smartphone to the embedded Hardware. This Hardware is using the Adafruit Feather Wing infrastructure. It shows a typical use case that can be modified to serve prototyping a multitude of possible User Applications including Sensors, Bluetooth Low Energy and a Smartphone. In this particular example one Host Board (Adafruit Feather M0), one Würth Elektronik Proteus Wing and one Würth Elektronik Sensor Wing are used. Plugging the boards together and installing the Demo firmware on the M0 the demo is ready to run. Firmware and Source code for firmware and App are available from https://github.com/orgs/WurthElektronik. The App was created using the Capacitor Framework by Ionic (https://capacitorjs.com).

UDP TCP Sender & Receiver puts essential network tools in your pocket. Send and receive UDP and TCP traffic, run ping tests, and see everything in clear, filterable logs—ideal for developers, admins, and anyone debugging or testing network connectivity. ► UDP • Listen on a port and receive UDP packets; your local IP is shown so others can send to you. • Send UDP messages to any IPv4 address and port. • Logs show every packet sent and received with timestamps. ► TCP Client • Connect to any host and port. • Send and receive text or hex; switch to hex mode for binary or raw data. • See connection status and all traffic in the log. ► TCP Server • Start a TCP server on a chosen port; the app shows your local IP for easy connection. • Accept multiple clients; send (broadcast) messages to all connected clients or work with individual connections. • Send and receive in text or hex with the same log view. ► Ping • Ping any host (domain or IP) to check reachability and latency. • Set the number of pings (1–100) and see results with round-trip times. ► General • Dark and light theme. • Filter logs (e.g. sent vs received) where available. • Clear logs anytime. Portrait-oriented layout for comfortable one-handed use. Built for quick network checks, prototyping, and debugging—no account required. Free to use, with ads to support development.
