Frequently Asked Questions
What is the default Bluetooth pairing code for HC-02?
The HC-02 module uses the standard Bluetooth PIN “1234” (or “0000” on some firmware versions) for initial pairing. You can enter this code when prompted by your host device.
Can I use HC-02 as a master device?
No, the HC-02 operates as a slave-only module. If you need master functionality, pair an HC-05 configured as a master with this HC-02 slave module for two-way communication.
What is the effective wireless range of the HC-02 module?
In open air, the HC-02 achieves up to approximately 10 meters of reliable Bluetooth connectivity. Obstacles and interference may reduce this range in practical environments.
