Back in 2006, before the rise of iPhones and Androids, I created Mobuds, a pioneering mobile app built in Java J2ME. Designed for chatting — and yes, dating too — it worked on early mobile phones long before the app ecosystem we take for granted existed.
Mobuds enabled a Bluetooth-based mesh network between nearby devices. Phones running the app could:
- Connect directly to others nearby
- Estimate proximity based on the number of Bluetooth "hops"
- Share messages and user-profiles across the mesh — without the internet
- Creating a hyper-local social network, syncing with a website to find matches and build connections later on.
Each user had a basic profile (nickname, age, gender) that could be discovered and shared across the mesh network.
To expand its reach, I designed the concept of a "mo-hub" — a fixed Bluetooth node that could:
- Act as a central relay to extend mesh range
- Connect venues together (extending the mesh)
- Serve localized ads to nearby devices (potential monetization)
Mobuds tackled the limitations of early mobile platforms with some clever solutions:
- Built in Java J2ME
- Worked on pre-smartphone devices
- Used Bluetooth service descriptions to passively broadcast messages even when direct connections weren’t possible
- Included:
- ✅ Friends list
- 🚫 Block list
- 🔔 Proximity alerts (get notified when someone matching criteria is nearby)
This was essential in an era where:
- Internet data was expensive
- GPS was rare
- Bluetooth support was inconsistent
Although a patent was drafted and submitted (2007) for the core technology, it wasn’t completed due to cost. However, this work exists as prior art, protecting it from being re-patented.
A draft of the patent application is included in this repository for reference (UK Application 0717040.0, Publication GB2455964. The other name of the Patent was in charge of graphic/website design) .
This was my first Java project — and a steep learning curve. When smartphones arrived, I didn’t have the resources to port Mobuds to iOS or Android.
Still, I’m proud of what it achieved:
A fully offline, peer-to-peer Bluetooth chat and discovery network — before the world was ready.
I’m releasing this code as a reference for anyone interested in:
- Offline communication
- Bluetooth mesh networks
- Early mobile application architecture
- Peer-to-peer discovery
⚠️ If someone claims they invented Bluetooth Mesh Messaging after 2006 — remind them:
Mobuds got there first. (check the domain name registration date!)
