Onboarding Service

The Onboarding service provides a common and simple way for new device to be brought onto the Wi-Fi network. This is especially useful for devices that have a limited user interface, like a SmartPlug.

How Does it Work?

The current onboarding mechanism leverages Wi-Fi only, though the system can evolve to leverages additional hardware (like BTLE) as they become more prelevant in these class of devices.

Two roles are supported:

  • Onboardee. This is the device that is unconfigured and needs to be brought onto the Wi-Fi network.

  • Onboarder. This is the device is configuring the Onboardee device, typically a mobile application or PC.

The following are the steps to onboard a device.

1. Onboardee broadcasts its SSID

When an Onboardee device is first plugged in, it will advertise its SSID over Wi-Fi. The SSID is either prefixed with "AJ_" or postfixed with "_AJ" to help indicate that this device that supports the AllJoyn™ Onboarding service.

2. Onboarder connects to Onboardee

The Onboarder will scan for unconfigured AllJoyn devices by looking for SSID names with "AJ_" or "_AJ". A user can then choose to onboard a specific Onboardee device. The first step is to connect to the Onboardee device's SSID. Depending on the Onboarder platform, this may be done automatically by the application.

3. Onboarder sends Wi-Fi credentials

After connecting to the Onboardee's SSID, the Onboarder will listen for AllJoyn About announcements. Then, the Onboarder will use the Onboarding service interfaces to send the target Wi-Fi network credentials to the Onboardee device.

4. Switch to target Wi-Fi network

Both devices will then switch to the target Wi-Fi network.

5. Onboarder listens for Onboardee device

As a final step, the Onboader will listen to receive About announcements from the Onboardee device. When received, the Onboarder considers the Onboardee device fully onboarded.
