Building a Bluetooth to Serial / UART Bridge Using an ESP32 and Arduino Part 2
In this video we look at how to make a wired to wireless serial / UART bridge using Bluetooth, ESP32, and the Arduino programming environment. In part 2 we look at a demo of the command mode that allows you to control the bridge settings, such as the Bluetooth device name and the serial communication baud rate. We then look at the command mode code and the code to save command mode settings to NV memory.
