ESP32 / ESP8266 Arduino: Printing numbers to serial in different bases

In this tutorial, we will check how we can print numbers to the serial port using different bases, more specifically in binary, octal and hexadecimal. The tests on the ESP32 were performed using a DFRobot’s ESP-WROOM-32 device integrated in a ESP32 FireBeetle board. The tests on the ESP8266 were performed on a DFRobot’s ESP8266 FireBeetle board.

ESP32 Arduino: Serial communication over Bluetooth Hello World

The objective of this post is to explain how to get started with the BluetoothSerial ESP32 library, in order to send data to a emulated Serial connection, operating over Bluetooth classic. The tests of this ESP32 tutorial were performed using a DFRobot’s ESP-WROOM-32 device integrated in a ESP32 FireBeetle board.
