The Pokémon GO Plus is a small device that lets you enjoy Pokémon GO while you’re on the move and not looking at your smartphone. The device connects to a smartphone via Bluetooth low energy and notifies you about events in the game—such as the appearance of a Pokémon nearby—using an LED and vibration.
The Pokémon GO Plus will begin to blink and vibrate whenever you’re within range of a PokéStop. Press the Pokémon GO Plus button to search the PokéStop for items. If you find any items, they’ll immediately be added to your inventory.
When a Pokémon is near, the light on the Pokémon GO Plus will flash. It will also flash and vibrate when you pass a PokéStop. Once a Pokémon is close, press the button on the Pokémon GO Plus to throw a Poké Ball. The Pokémon GO Plus will flash and vibrate to let you know if you were successful in catching the Pokémon.
