A miniature research model demonstrating how wireless interference affects Bluetooth protocol stability.
Author: Abdullah Yasir · Cyber X
يقدّم هذا المشروع نموذجاً مصغراً يبيّن كيف يؤثر التداخل اللاسلكي على بروتوكولات البلوتوث.
This project is a scaled-down educational model showing how radio-frequency interference impacts Bluetooth communications. It is designed to help students understand protocol behavior under non-ideal conditions — not as a deployable product.
| Component | Role |
|---|---|
| ESP32 WROOM | Main development board |
| nRF radio module | Additional RF interface for interference generation |
| Custom firmware | Generates controlled interference in the Bluetooth frequency band |
The setup was evaluated in a controlled lab environment against:
- Bluetooth earbuds (AirPods-class devices)
- Bluetooth speakers
- Car audio recorders / Bluetooth head units
At close range and in open areas, targeted devices frequently stopped audio output when interference was active — demonstrating how fragile Bluetooth links can be under RF congestion or deliberate jamming.
Understand how the Bluetooth protocol behaves under non-ideal RF conditions:
- Packet loss under interference
- Connection stability degradation
- Range-dependent failure modes
- Why critical systems should not rely solely on unlicensed 2.4 GHz wireless

The custom firmware is on the physical ESP32 WROOM board — it was not found on this development machine. See firmware/README.md for how to export and add the sketch when you have the device.
⚠️ EDUCATIONAL / LAB USE ONLY
- Intentionally jamming or disrupting wireless communications is illegal in most countries outside licensed research facilities
- This demo was conducted in a controlled test environment
- Do not use interference techniques on public airspace, commercial devices, or networks you do not own
- Understand your local telecommunications regulations before any RF experimentation
You are solely responsible for compliance with applicable laws.
