The automated hardware-in-the-loop environment relies on physical USB connections linking an Android smartphone and the ESP32-C6 microcontroller directly to the Groundrun rig. Claude Code was granted access to the rig and operated toward defined objectives to generate the testing programs. The system rigorously evaluates five separate provisioning mechanisms, including Bluetooth Low Energy, Soft AP, Wi-Fi captive portals, SmartConfig (ESPTouch v2), and Wi-Fi Protected Setup. These workflows comprehensively verify varying credential transfer pathways, from encoded network broadcasts to router button presses.

The first thing a customer does with a new Wi-Fi-enabled connected product is complete the Wi-Fi setup, so it has to be reliable and work every time, no matter what else changes in the product.
This is something we can do with the Groundrun system. Let's set it up.
Setting It Up
First we need to get the hardware in the loop, the same way we did for testing an over-the-air (OTA) update on the ESP32. We used an ESP32-C6 devboard from Espressif for this test. With Groundrun, getting it into the loop is easy: we just do this:
- Connect the ESP32-C6 board via USB to the Groundrun rig.
- Connect an Android phone via USB to the same Groundrun rig.
And that's it.
Wi-Fi Commissioning
There are several ways to set up a Wi-Fi network on a connected device, and the ESP32 family supports a range of them:
- Bluetooth. The phone pairs with the board over Bluetooth Low Energy and sends it the network name and password directly.
A Ratatui maintainer has developed an experimental protocol that draws boundaries along cell edges to solve long-standing layout inefficiencies in command-line tools. Standard interfaces waste precious display area and frustrate users by capturing border characters during copy operations. By freeing up lines previously lost to framing, this initiative enables modern UI components like edge-aligned tabs and compact buttons without sacrificing character real estate.
The revamped e-reader portfolio introduces color E-Ink technology aimed at users reading comics, graphic novels, and cookbooks. While the hardware offers functional enhancements like multi-colored highlighting and a lighter chassis, its substantial cost positions it well above standard e-reading alternatives. Budget-conscious consumers may find the updated monochrome devices provide significantly better overall value.
Security researchers discovered that unhashed configuration files in the smart home platform expose token secrets and signing keys to anyone with file-read access. This architectural flaw directly endangers roughly two million households by compromising physical controls such as alarms, garages, and door locks. Because standard credential resets fail to revoke these credentials, unauthorized access can persist indefinitely once files are exposed.
