Bluetooth Command Settings for Embedded Systems

3.3.1 Bluetooth Command Settings Knowledge

The embedded Bluetooth serial communication module allows us to break free from the constraints of cables and achieve wireless serial communication within a limited range, with two working modes: command response mode and automatic connection mode. In automatic connection mode, the module can be divided into three roles: Master, Slave, and Loopback. When the module is in automatic connection mode, it will automatically connect according to the pre-set data transmission method; when the module is

DIY Voice-Controlled RGB LED Strip

This project will use a smartphone to set the color of the RGB LED strip. These RGB strips have built-in Bluetooth functionality and can receive commands sent from an Android application on the smartphone. This way, we can control the color of the RGB LED strip through the phone. If you think this is not cool enough, the latter part of the article introduces the making of a voice-controlled RGB LED strip, the same circuit, two uses!

Using PS4 Controller as an Arduino Controller

This article is from the homepage of Curious Ya Bin.
There are many posts abroad about using a PS4 controller as an Arduino remote control (because the original works are mostly abroad). I searched for information in domestic communities and forums, and there is almost none on this topic, with the most being about PS2 controllers and some about PS3 controllers, but the information is not comprehensive. Recently, I managed to control Arduino with a PS4 controller via Bluetooth, so I

Exploring Bluetooth and WiFi6 with These Two Development Boards

Keywords：Bluetooth, WiFi6, Development Board Review
Abstract：Nordic is a representative IoT connectivity chip provider from Norway, leading the global BLE market. This article provides a detailed introduction to the performance, resources, and acquisition channels of Nordic's nRF5340 Audio Bluetooth development board and nRF7002 WiFi development board.
Currently, the commonly used wireless communication technologies can be roughly divided into: short-range wireless communication and long-range wireless communication based on transmission distance. Short-range wireless communication includes WiFi, Bluetooth, ZigBee, NFC, UWB, etc. Long-range wireless communication includes
