WiFi Direct P2P File Transfer Kit with ESP32 + LED
Transfer Files Anywhere Without a Router: ESP32 WiFi Direct P2P File Transfer Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine sharing sensor logs, firmware updates, or project files between two devices in a lab, at a hackathon, or in a remote field site — all without a router, hotspot, or internet connection. With this kit, you’ll build a fully functional peer-to-peer file transfer system using ESP32’s WiFi Direct capabilities, complete with OLED status displays and microSD storage for saved files.
What You'll Build
You’ll assemble and program two identical ESP32 nodes that discover each other over WiFi Direct, establish a TCP connection, and send files stored on microSD cards. Each node’s OLED screen shows connection status and transfer progress, giving you a tangible networking lab that mimics real-world device-to-device communication systems.
What You'll Learn
- Configuring ESP32 WiFi in Direct (P2P) mode without an access point
- Setting up TCP server-client connections over a direct WiFi link
- Reading and writing files to a microSD card using SPI interface
- Displaying real-time connection and transfer data on an OLED screen via I2C

Who This Kit Is For
This kit is designed for CBSE Class 11-12 students building networking projects, B.Tech ECE and EEE undergraduates working on embedded communication labs, participants of Smart India Hackathon who need rapid prototyping of device-to-device data exchange, and ATL Tinkering Lab mentors exploring wireless IoT solutions. If you’ve ever struggled to demonstrate a standalone file transfer system that works right out of the box, this kit puts all the hardware and guidance in your hands.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.

Do I need a Wi-Fi router or internet connection for the file transfer to work?
No. The two ESP32 boards establish a direct WiFi Direct (P2P) link, so you can transfer files anywhere — even in remote labs or field project sites without any network infrastructure.
Can I modify the code to transfer different types of files, like images or firmware binaries?
Absolutely. The open-source sketches support any file type. With microSD cards on both nodes, you can adapt the system to exchange sensor data, images, configuration files, or over-the-air update payloads.
Is soldering experience necessary, and does the kit include all tools?
The kit contains a soldering iron, solder wire, and PCB prototype boards. Basic soldering skills are useful, but the AI companion provides step-by-step assembly guidance, making it achievable even for those new to through-hole soldering.
Two ESP32 boards transfer files directly over WiFi Direct without any router using TCP socket.
