Improv WiFi: Open standard for setting up Wi-Fi via Bluetooth LE #IoT @nabucasa
Lots of methods of varying user-friendliness and implementation difficulty exist to configure a device with a Wi-Fi network. However, there is no standard method of easily configuring a device’s WiFi credentials.
CircuitPython uses an on-disk secrets.py file which we’ve found to be useful for entering credentials, but a device’s filesystem is often not exposed. Existing projects using captive portals suffer from an increased overhead – using a captive portal requires the inclusion of a lightweight DNS server in addition to the captive portal handling code.
Improv is a new initiative funded by Nabu Casa which promises a “free and open standard with ready-made SDKs that offer a great user experience to configure Wi-Fi on devices”. It’s currently implemented by the latest version of the ESPHome project (also part of Nabu Casa’s Home Assistant). Improv seeks to connect a device to Wi-Fi via Bluetooth Low Energy (BLE).
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
