Please check one by one if the following issues exist:
- Check the SSID and password of the router input on the mobile app.
- Check if the pairing mode and connection mode are set correctly. The recommended pairing mode and connection mode are PARING_MODE_WIFI_AP and TUYA_IPC_LINK_WIFI respectively.
- Check if all the requiredtkl_wifi.cAPIs are adapted.
- Verify if tkl_wifi_init(WIFI_EVENT_CB cb) proactively notifies the SDK of the current network status when the network changes.
