To make the Badge WX visible to BlocklyProp, you will need the WiFi Access Point's login and password. You will enter this information right on the Badge WX, using the startup menu that automatically appears on its display, and the rocker buttons on the top edge of the board.
A few seconds later, if it successfully associated, the Badge WX will report "Connected!" along with the Wi-Fi Access Point name and the IP address it received.
The On/Off Button has many uses! You can read about them all in the Badge WX Product Guide. If you find your Badge WX is in a strange, unknown state and you want to start over, just press the On/Off button again; you should see two slow blinks and then it will turn off. If the PWR LED is already blinking, wait for it to stop before trying to turn it off. Button presses are not recognized while the PWR LED is lit (on).
