Troubleshooting

This topic describes the common questions about the development of pet water fountain pumps 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, mismatched I/O configuration or incorrect active level.
   • The hardware problems indicate 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.

• Hardware peripheral problems: Make sure you have performed a production test on the device.
• Network problems: Connect the device to a new wireless network and pair it with the mobile app in access point (AP) mode.
• Software problems: Supply the module with DC power individually to test the module functionality.
• Hardware problems: Supply the module with DC power individually to check whether the module can work properly.
• Circuit problems: If the device does not have the above problems, verify the circuit.

FAQs

• Water fountain pump problems

  1. Check whether the pump control type matches the configuration file.
  2. Check whether the pulse width modulation (PWM) control I/O or speed control I/O is correct.
  3. Check the circuit design.

• Lighting problems

  1. Check whether the pin configuration and trigger level are configured correctly.
  2. Check whether the colored light is broken.
  3. Check the circuit design.
