AT commands refer to a set of commands used to control a Bluetooth module. These commands are often used to configure and manage a Bluetooth connection.
AT commands are sent to a Bluetooth module over a serial connection and can be used to set a variety of Bluetooth parameters such as the identity of the device, the name of the device, the baud rate, the packet type, security settings, and other configuration settings. When a command is sent, the Bluetooth module will respond with an acknowledgement message.
The AT command set is a useful tool for configuring and managing a Bluetooth connection. It can be used to configure a Bluetooth module for use in a variety of applications, such as a wireless headset or an automated home system. It also allows developers to quickly test and debug a Bluetooth connection.
AT commands can also be used to control a Bluetooth module remotely, such as from a web or mobile application. By sending AT commands to the module, it is possible to control the module from a remote location. This can be useful for setting up a remote control system, or for monitoring the status of a device that is connected to a Bluetooth module.
The AT command set is a powerful tool for developers, and can be used to create sophisticated Bluetooth-controlled devices. By understanding the AT commands and their syntax, developers can quickly and easily configure and manage Bluetooth connections.
In summary, the AT command set is a useful tool for configuring and managing a Bluetooth module. By understanding the syntax and capabilities of the AT command set, developers can quickly and easily configure and manage Bluetooth connections, and can use the AT command set to implement a wide range of features and applications.
