The Framework for Internal Navigation and Discovery (FIND) is like indoor GPS for your house or business, using only a simple smartphone or laptop.

This version, 3.X, is a complete re-write of the previous versions 2.x.

About the project

This repository is a complete re-write of the previous version of FIND (github.com/schollz/find). There are notable improvements from the previous version:

• Support for any data source - Bluetooth / WiFi / magnetic fields / etc. (previously just WiFi)
• Passive scanning built-in (previously required a separate server)
• Support for Bluetooth scanning in scanning utility (previously just WiFi)
• Meta-learning with 10 different machine learning classifiers (previously just three)
• Client uses Websockets+React which reduces bandwidth (and coding complexity)
• Rolling compression of MAC addresses for much smaller on-disk databases (see stringsizer)
• Data storage in SQLite-database (previously it was BoltDB)
• Released under MIT license (more commercially compatible than AGPL)

The API for sending fingerprints (/track and /learn) and MQTT endpoints are backward compatible.

Status

FIND3 is stable and ready for use.

• Machine learning server (this repo)
• Command-line tool for gathering fingerprints (schollz/find3-cli-scanner)
• Android app for gathering fingerprints (schollz/find3-android-scanner)
• ESP code for gathering fingerprints with ESP8266/ESP32 (DatanoiseTV/esp-find3-client)
