#179 Was it worth waiting for Bluetooth? How Much Current Needs the ESP32 Bluetooth in BLE?

Is ESP32 BLE really power efficient? How does it compare with Wi-Fi? And with a dedicated BLE beacon? Power is a precious good in battery powered devices. Today we will investigate how much power a ESP32 burns in normal mode, using Wi-Fi or Bluetooth, in deep-sleep, and in mixed scenarios where it sleeps and sends data every few seconds. The beacon I used contains an N51822 chip Links: BLE Beacon Sketch: https://github.com/ibm-watson-iot/dev...
