Automating Wi-Fi setup testing on the ESP32

Groundrun has developed an automated testing system for Wi-Fi setup on ESP32 devices by connecting the microcontroller and an Android phone via USB to a testing rig. The system tests multiple Wi-Fi commissioning methods supported by ESP32, including Bluetooth, Soft AP, captive portals, SmartConfig, and WPS, using a custom smartphone app and firmware developed with AI assistance. This automation ensures that Wi-Fi setup—typically the first customer interaction with a connected product—remains reliable and functions consistently across product changes.
