Using discoverable peer-to-peer services to allow remote onboarding of headless devices over a Wi-Fi network

摘要

The disclosure relates to using discoverable peer-to-peer (P2P) services to remotely “onboard” headless devices over a Wi-Fi network. In particular, an onboardee device may enter an onboarding mode in which the onboardee device becomes a Wi-Fi access point (AP) and an onboarder device connected to a private Wi-Fi network may discover the onboardee device and establish a secured session to engage with the P2P services running thereon. The first time that the onboarder device and the onboardee device engage with one another, the secured session may be established based on a key exchange that uses a well-known secret (e.g., a default passphrase), which may be immediately changed to a shared secret. The onboarder device may then transfer an onboarding configuration to the onboardee device, which may be instructed to validate the onboarding configuration and connect to the Wi-Fi network prior to entering the connected mode.

主权项

1. A method for onboarding a headless device to a personal Wi-Fi network with an onboarder device over an onboarding-Wi-Fi network, the method comprising:
connecting the onboarder device with a software access point (SoftAP) corresponding to the headless device over the onboarding-Wi-Fi network; connecting the onboarder device and the headless device via a peer-to-peer connection; configuring, at the onboarder device and via the peer-to-peer connection, the headless device via a service operating on the headless device to enable the headless device to connect with a personal access point (AP) of the personal Wi-Fi network and leave an onboarding mode; attempting, at the onboarder device and via the peer-to-peer connection, to identify the headless device operating on the personal Wi-Fi network; rediscovering, at the onboarder device, the headless device operating in the onboarding mode on the onboarding-Wi-Fi network in response to an onboarding device being unable to identify the headless device on the personal Wi-Fi network; obtaining, at the onboarder device and via the SoftAP, information about an attempt by the headless device to connect to the personal Wi-Fi network; reconfiguring, at the onboarder device, the headless device via the service over the peer-to-peer connection to enable the headless device to connect with the personal AP of the personal Wi-Fi network.
