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)

(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?
