RF Testing

[中文]

1. What should I do if the EspRFTestTool Toolkit fails to flash?

The chip might not have entered download mode correctly. Follow these steps to troubleshoot:

  • Check the log: Use a serial tool (such as sscom, Serial Port Utility), select the correct baud rate, and check the log after powering up the chip.

  • Confirm download mode: When the chip enters download mode, it typically displays “wait for download.”

  • Check the connections: If no log is printed, ensure that the power supply and UART connections are functioning properly.

2. How can I confirm whether the firmware was successfully flashed?

Even if the flashing tool indicates success, the firmware might not have been flashed correctly. Follow these steps to verify:

  • Check the log: Close the serial port used by the flashing tool, open a serial tool (such as sscom, Serial Port Utility), select the correct baud rate, and check the log.

  • Enter working mode: Pull up the Boot pin and re-power the chip to enter working mode.

  • Confirm flash success: Check if the log shows continuous reboots or matches the expected behavior based on the firmware documentation to confirm if the flashing was successful.

3. What should I do if the running traffic fails in the Wi-Fi Adaptivity Test?

If running traffic fails, consider the following possible causes and solutions:

  • Firmware issues: Ensure that the firmware was flashed successfully.

  • Network issues: Check whether the router (AP) network is stable and connections are smooth.

  • Connection delays: If the connection is slow, wait a few seconds and restart running traffic.

  • Serial testing: If the issue persists, consider testing via serial commands.
