This topic describes the common questions about aroma diffuser development to help you troubleshoot problems.
How to identify problems
-
Troubleshoot problems according to the test cases.
-
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.
-
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.
FAQs
-
Buzzer issues
- Check whether the buzzer type matches the configuration file.
- If you use passive buzzers, check whether the frequency is correctly configured.
- Check the circuit design.
-
Mist issues
- Check whether the atomizer pin can output PWM signals properly.
- Check whether the fan can rotate properly.
- Check the circuit design.
-
Ambient light issues
- Check whether the pin configuration and trigger level are configured correctly.
- Check the PWM frequency of the ambient light.
