Frequently Asked Questions

How do I program the DFRobot Beetle BLE board?

You can program the Beetle BLE using the standard Arduino IDE. Connect the board via its Micro USB port, select 'Arduino Uno' as the board type, and upload your sketch. No additional libraries or core installations are required for basic functionality. The board also supports wireless programming over Bluetooth using the DFRobot Bluno firmware update method.

What is the power supply requirement for the Beetle BLE?

The primary power source is the Micro USB port, which provides 5V. The board can also accept an external input voltage of less than 8V via its VIN pad. Ensure your power supply can deliver sufficient current for the ATmega328P and the active BLE radio, especially during transmission peaks, to maintain stable operation.

How do I use the Bluetooth HID or iBeacon features?

The BLE module supports HID and iBeacon modes out of the box. You typically control these modes via specific AT commands sent over the serial interface. For HID, you can emulate keyboard or mouse inputs. For iBeacon, you configure the UUID, Major, and Minor values to broadcast a proximity signal detectable by smartphones. Refer to DFRobot's documentation for the exact command set and examples.

Can I connect external sensors to the Beetle BLE's I/O pads?

Yes, the gold-plated V-shaped pads provide access to digital I/O, analog inputs, and I2C pins. You can solder wires directly to these pads or use conductive thread for wearable projects. The pin mapping follows the standard Arduino Uno layout, so existing shield libraries for sensors, displays, or actuators are generally compatible with appropriate wiring.
