FAQ Section
FAQ Section
Q. Do I need to install specific drivers for this adapter?
A. No, the HC-USB-T is designed for plug-and-play functionality. It generally utilizes standard HID to serial conversion, allowing your PC to recognize it instantly without hunting for third-party drivers.
Q. Which Bluetooth modules are compatible with this test rack?
A. It is highly compatible with standard UART Bluetooth modules such as the HC-02, HC-05, and HC-06, as long as they operate on a 3.3V logic level and follow standard RX/TX serial communication.
Q. How do I enter AT command mode using this board?
A. Ensure the Bluetooth module is unconnected from other Bluetooth devices (unpaired state). Connect the module to the adapter, plug it into your PC, and use a serial port assistant software. The module's indicator light should flash, indicating it is ready to receive AT commands.
