ESP32 Peer to Peer File Transfer Kit with ESP32 + LED
ESP32 Peer-to-Peer File Transfer Kit – Master WiFi Direct TCP Server/Client
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 building a system where two ESP32 devices exchange data directly over WiFi without any router or access point — a true peer-to-peer network. This kit equips you to create a robust file transfer protocol using TCP sockets, giving you deep understanding of low-level networking on microcontrollers.
What You'll Build
You'll assemble two identical ESP32 units, each with an SD card for storage and an OLED display for status feedback. One unit acts as the TCP server, the other as the client, and they negotiate and transfer files wirelessly with full handshaking. When done, you can send any binary file between the two devices in seconds, perfect for offline data sharing in field projects or hackathon prototypes.
What You'll Learn
- Implement TCP server/client architecture on ESP32 for reliable file transfer
- Configure WiFi Direct (WiFi P2P) mode so ESP32s connect without an access point
- Interface SPI peripherals: MicroSD card for storage and 0.96‑inch OLED for progress display
- Debug socket communication, manage buffer sizes, and handle partial transfers gracefully

Who This Kit Is For
B.Tech ECE/EEE students tackling Smart India Hackathon projects that demand offline device communication will find this kit directly applicable. It’s also ideal for ATL Tinkering Lab mentors introducing advanced IoT concepts, and for IIT/NIT/VIT undergraduates who need a ready-made P2P networking project that demonstrates core TCP/IP principles without cloud dependency.
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.
What if I get stuck during the build?
Scan the QR code for the AI companion trained on this TCP file‑transfer project, or message us on WhatsApp for live human guidance within project hours.
Do I need my own microSD cards?
Yes — the kit includes two MicroSD modules, but you supply your own microSD cards (any capacity up to 32GB, formatted FAT32, works best).
Can I transfer only text files, or any binary data?
The TCP server/client code handles raw binary streams, so you can send images, log files, sensor data, or any file type without modification.
What if a file transfer fails midway?
The AI companion covers debugging steps for socket timeouts and buffer overflows, and the WhatsApp team can inspect your code if the issue persists.
Two ESP32 boards transfer files over WiFi direct P2P without router using TCP socket server/client.
