ESP32 BLE ibeacon broadcaster & tracker

Work in progress to implement an BLE sniffer sending packets through REST

Installation

• Install ESP32 toolchain as described here. I currently use 1.22.0-75
• Clone esp-idf and set its IDF_PATH environment variable. I use v3.0-rc1
• Run make menuconfig
  • Network configuration to configure WiFi, iBeaon & REST Server
  • Component config
    • Bluetooth->Bluedroid Enable to activate GATT client module(GATTC)

Objectives

• (Partially Implemtented) Scan for BLE iBeacon (Search for ~500ms)
• (TODO) Report iBeacons Detected to HTTP Server via REST POST {[{'name': 'ibeaconA', 'uuid': '00000000-0000-0000-0000-000000000000', 'major': 0, 'minor': 0}]}
• (TODO) Broadcast iBeacon every ~500ms
• (TODO) ID if Broadcast & Search be done synchronously?
• (TODO) update OTA
• (TODO) SetConfig via txt / REST
