WiFi Web Server LED Blink
A simple web server that lets you blink an LED via the web.
This sketch will create a new access point (with no password).
It will then launch a new server and print out the IP address
to the Serial monitor. From there, you can open that address in a web browser
to turn on and off the LED on pin 13.
If the IP address of your shield is yourAddress:
http://yourAddress/H turns the LED on
http://yourAddress/L turns it off

Located in Southern California, this Harrah's resort has one of the biggest and most active casinos in the region, with over 1,700 slot machines and nearly 60 exciting table games, including poker and blackjack. Harrah's does charge $11.95 (as of Feb) for 24 hour internet access. The Venetian is an app. 5-10 minute walk from Harrah's (if indeed there is free wifi in the food court.I don't know). For us, I feel it is worth it to pay the daily fee, rather than dragging the laptop/netbook around.
Android 10 introduces support for the Wi-Fi Alliance's(WFA) Wi-Fi Protected Access version 3 (WPA3) and Wi-Fi Enhanced Openstandards. For moreinformation, seeSecurity on the WFA site.
WPA3 is a new WFA security standard for personal and enterprisenetworks. It aims to improve overall Wi-Fi security by using modern securityalgorithms and stronger cipher suites. WPA3 has two parts:
- WPA3-Personal: Uses simultaneous authentication of equals (SAE)instead of pre-shared key (PSK), providing users with stronger securityprotections against attacks such as offline dictionary attacks, keyrecovery, and message forging.
- WPA3-Enterprise: Offers stronger authentication and link-layerencryption methods, and an optional 192-bit security mode for sensitivesecurity environments.
Wi-Fi Enhanced Open is a new WFA security standard for publicnetworks based on opportunistic wireless encryption (OWE). It providesencryption and privacy on open, non-password-protected networks in areas such ascafes, hotels, restaurants, and libraries. Enhanced Open doesn't provideauthentication.
WPA3 and Wi-Fi Enhanced Open improve overall Wi-Fi security, providing betterprivacy and robustness against known attacks. As many devices don't yet supportthese standards or haven't yet had software upgrades to support these features,WFA has proposed the following transition modes:
- WPA2/WPA3 transition mode: The serving access point supports bothstandards concurrently. In this mode, Android 10devices use WPA3 to connect, and devices running Android 9 or lower useWPA2 to connect to the same access point.
- OWE transition mode: The serving access point supports both OWE and openstandards concurrently. In this mode, Android 10devices use OWE to connect, and devices running Android 9 or lower connectto the same access point without any encryption.
https://softlearn.mystrikingly.com/blog/dolphins-pearl-online. WPA3 and Wi-Fi Enhanced Open are supported only in client mode.

Implementation
To support WPA3 and Wi-Fi Enhanced Open, implement the supplicant HAL interfacedesign language (HIDL) provided in the Android Open Source Project (AOSP) athardware/interfaces/wifi/supplicant/1.3/.
The following are required to support WPA3 and OWE: Casinos in south florida.
Linux kernel patches to support SAE and OWE
- cfg80211
- nl80211
wpa_supplicantwith support for SAE, SUITEB192 and OWEWi-Fi driver with support for SAE, SUITEB192, and OWE
Wi-Fi firmware with support for SAE, SUITEB192, and OWE
Wi-Fi chip with support for WPA3 and OWE
Public API methods are available in Android 10 to allowapps to determine device support for these features:
WifiConfiguration.java contains new key management types, as well as pairwise ciphers, group ciphers,group management ciphers, and Suite B ciphers, which are required for OWE,WPA3-Personal, and WPA3-Enterprise.
Enabling WPA3 and Wi-Fi Enhanced Open
To enable WPA3-Personal, WPA3-Enterprise, and Wi-Fi Enhanced Open in the Androidframework:
Quick hits online slots. Ruby fortune contact. WPA3-Personal: Include the
CONFIG_SAEcompilation option in thewpa_supplicantconfiguration file.WPA3-Enterprise: Include the
CONFIG_SUITEB192andCONFIG_SUITEBcompilation options in thewpa_supplicantconfiguration file.Wi-Fi Enhanced Open: Include the
CONFIG_OWEcompilation option in thewpa_supplicantconfiguration file.
If WPA3-Personal, WPA3-Enterprise, or Wi-Fi Enhanced Open aren't enabled, userswon't be able to manually add, scan, or connect to these types of networks.
