  1. Connect gadget to power
  2. Client application uses Improv to send the Wi-Fi credentials to the gadget
  3. The gadget will connect to the wireless network and returns a URL

The problem we're solving

Getting your Wi-Fi gadget connected is often a bad user experience.

A lot of devices require to be connected to the network to be controlled or receive data. The majority of these devices use Wi-Fi to establish a connection with a local application or the cloud.

Configuring a device to connect to your Wi-Fi is a pain. The most common approach is Soft Enabled Access Point. The device starts its own Wi-Fi access point, the user connects to it with their phone/computer and then interacts directly with the device via an app or a website served from the device.

It’s easy for something to go wrong. The user submits incorrect Wi-Fi credentials or the phone loses access to the access point. In such cases it is difficult to recover. Phones also have a bad time dealing with access points that don’t provide internet access.

Improv Scope & Constraints

The goal of the standard is to get the device connected to the Wi-Fi via Bluetooth Low Energy (BLE). It is not the goal to offer a way for devices to share data or control. The standard should work without requiring the device to contain a screen.
