Automating Wi-Fi setup testing on the ESP32
Groundrun demonstrates automated hardware-in-the-loop testing for five different Wi-Fi commissioning methods on an ESP32-C6 microcontroller using AI agents.
summary is enough Skim this to see practical timing and quirks of five ESP32 Wi-Fi commissioning methods, though the core is a product pitch for Groundrun.
summary
The article walks through automating the testing of five Wi-Fi setup methods—Bluetooth, Soft AP, Captive Portal, SmartConfig, and WPS—on an ESP32-C6 board using the Groundrun hardware-in-the-loop platform and Claude for code generation. By connecting an Android phone and the devboard to a test rig, the system measures execution times and exposes protocol-specific quirks like captive portal timeout windows and SmartConfig variance. The approach enables continuous integration regression testing for critical customer onboarding flows.
key points
- Evaluates five ESP32 Wi-Fi setup methods: Bluetooth, Soft AP, Captive Portal, SmartConfig, and WPS.
- Uses AI coding agents to generate the necessary test firmware and a basic Android companion app.
- Identifies protocol quirks such as strict operating system timeout windows in captive portals and timing variance in SmartConfig.
