6. Naudojimo instrukcijos

6.1 Bluetooth poravimas

1. Power on the module. The blue work indicator will illuminate, indicating it is ready for pairing.
2. Mobiliajame įrenginyje (išmaniajame telefone, planšetiniame kompiuteryje ir kt.) įjunkite „Bluetooth“ ir ieškokite galimų įrenginių.
3. Select the device named 'JieLi BR21' (or a similar identifier) from the list to initiate pairing.
4. Once successfully paired, the blue indicator's blinking pattern may change or become solid.

6.2 Garso atkūrimas

After successful Bluetooth pairing, you can play audio from your connected device. The module will output stereo sound through the connected speakers. Volume control is managed directly from your paired Bluetooth source device.

6.3 Automatic Reconnection and Shutdown

• The module is designed to automatically reconnect to the last paired device after being powered off and on again.
• To conserve power, the board will automatically shut down if it remains in standby mode for 10 minutes without an active Bluetooth connection.

7. Problemų sprendimas

• Nėra garso:
  • Check all power supply connections and ensure the module is powered on.
  • Patikrinkite garsiakalbių jungtis ir įsitikinkite, kad jos tinkamai sujungtos.
  • Confirm that Bluetooth pairing is successful and audio is actively playing on the source device.
  • Ensure speaker impedance (2-8 ohm) and wattage (3-10W) are compatible with the module.
• Prasta garso kokybė / triukšmas:
  • Ensure a stable 3.7V lithium battery (with protection) or a clean 5V DC power supply is used. Unstable power sources can introduce noise.
  • Keep the module away from metal objects or strong electromagnetic interference sources.
  • Patikrinkite, ar nėra atsilaisvinusių jungčių ar pažeistų laidų.
• Nepavyksta susieti „Bluetooth“:
  • Ensure the module is powered on and within the approximate 15-meter transmission range of your source device.
  • Turn off and then on Bluetooth on your source device, then try searching for devices again.
  • If previously paired, try 'forgetting' or 'unpairing' the device on your source device and then re-pairing.
• Module Shuts Down Unexpectedly:
  • This is normal behavior if the module is in standby mode for 10 minutes without an active Bluetooth connection. Reconnect your Bluetooth device to reactivate it.
  • If it shuts down during active use, check the stability and voltage iš jūsų maitinimo šaltinio.
