In Chapter 12 (GPS tracking app with Google Maps), data is transmitted to an app on an Android tablet or mobile phone by an ESP32 microcontroller with Bluetooth communication. In Chapter 10 (Build an app), an HC-05 Bluetooth module is connected to an ESP8266 development board to communicate with an app. If the device to transfer data to an app does not have Bluetooth functionality, then USB OTG (On-the-Go) communication connects the device with the app. In this chapter, the device without Bluetooth functionality is an Arduino Uno. An HC-05 Bluetooth module could be connected ...
