Network breakdown re-access method based on internet of things embedded Wi-Fi module

Abstract

The invention discloses a network breakdown re-access method based on an internet of things embedded Wi-Fi module. The method comprises the steps that the Wi-Fi module is powered on in an STA mode; whether a designated router is searched for or not is judged, and if the designated router is searched for, the Wi-Fi module has access to the designated router; if the designated router is not searched for, the module waits for a while, is automatically switched to an AP mode, and works for a while in the AP mode, whether the designated router is searched for or not is continuously judged, and if the designated router is not searched for, the steps are continuously circulated; if the designated router is searched for, the module is switched back to the STA mode and has access to the designated router. Due to an outage or a network breakdown or poor signals, the router can not be connected with the internet. When the power grid is restored and reconnection is required, the technical scheme is adopted, the complexity caused when home use consumer products like a smart home deal with the Wi-Fi network faults is greatly reduced, and the most critical problem of the popularization of an internet of things Wi-Fi device is solved.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things, in particular to a method for reconnecting after network disconnection based on an embedded Wi-Fi module of the Internet of Things. Background technique [0002] The Internet of Things revolution is enabling more and more new devices to connect wirelessly to home networks and the cloud. However, for most of these terminal devices without keyboards or touch screens, such as home appliances, lights, thermostats, treadmills, electronic scales, etc., when these products work in the wireless base station (STA) mode, the wireless router is powered off After the network connection is interrupted due to reasons such as poor signal or poor signal, how to make it successfully reconnect to the Wi-Fi network is a huge obstacle preventing it from becoming a widely deployed connected home product. For these products working in the wireless base station (STA) mode, if they want to re-connect to ...

AI Technical Summary

Problems solved by technology

When the wireless channel is disconnected, these configuration processes can only be realized by the operator through commands on the debugging interface (serial interface), and this can only be achieved with a certain background in wireless network technology. Difficult, almost impossible, for the vast majority of consumers of IoT home devices
