This topic describes the common questions about aroma diffuser development to help you troubleshoot problems.

How to identify problems

  1. Troubleshoot problems according to the test cases.

  2. Determine what caused the problem, which can be the configuration or the hardware.

    • The incorrect configuration indicates that the configuration file does not match your circuit design. For example, incorrect I/O configuration or PWM frequency of passive buzzer.
    • The hardware issues indicate that hardware design or soldering problems.
  3. Analyze what exactly causes the problems.

Common problems

You need to identify the problem source first and then proceed with troubleshooting.

  • Radio frequency: Make sure you have performed a production test on the failed device.
  • Network issues: Connect the device to a new wireless network and pair it with the mobile app by using the AP mode.
  • Software issues: Supply the module with DC power individually to test the module functionality.
  • Hardware issues: Supply the module with DC power individually to verify whether the module can work properly.
  • Circuit issues: If the device does not have the above issues, verify the circuit.


  • Buzzer issues

    1. Check whether the buzzer type matches the configuration file.
    2. If you use passive buzzers, check whether the frequency is correctly configured.
    3. Check the circuit design.
  • Mist issues

    1. Check whether the atomizer pin can output PWM signals properly.
    2. Check whether the fan can rotate properly.
    3. Check the circuit design.
  • Ambient light issues

    1. Check whether the pin configuration and trigger level are configured correctly.
    2. Check the PWM frequency of the ambient light.
    3. Check whether the color light is broken.
    4. Check the circuit design.
