Best Tool to Diagnose Intermittent Wi-Fi Drops on ESP32 in Home Automation Project?
Hey guys in my current ESP32-based home automation project, I'm experiencing intermittent Wi-Fi connection drops, particularly when multiple devices are connected simultaneously. The serial monitor logs the error: "E (22345) wifi: Disconnect reason: 202 (AUTH_FAIL)." I've already verified the network credentials and ensured the router is functioning properly. What tool or method should I use to diagnose and resolve this Wi-Fi connectivity issue: Wireshark, an ESP32 Wi-Fi Sniffer, or a Spectrum Analyzer.
Solution
To diagnose intermittent Wi-Fi connection drops on your ESP32 project, use the ESP32 Wi-Fi Sniffer to capture and analyze Wi-Fi traffic, which is ideal for identifying authentication failures or unauthorized disconnects. If interference or congestion is suspected, a Spectrum Analyzer can help pinpoint external sources like other networks or RF devices. Wireshark is best if you need to investigate deeper network-level issues such as TCP/IP errors. Start with the sniffer and use additional tools as needed based on the findings.
