You can change the baud rate by entering AT command mode and sending the specific baud rate command (e.g., AT+BAUD) as detailed in your module's manual.
A dual-mode Bluetooth module, like the JDY-32, supports both Classic Bluetooth (SPP) and Bluetooth Low Energy (BLE), allowing compatibility with a wider range of devices.
Connect the module to a serial interface, open a serial terminal with the correct default baud rate, and type your instructions. Many modules require AT commands to end with a carriage return and line feed.
