Pokémon GO Plus

The Pokémon GO Plus is small device that allows players to capture Pokémon while on the move without having to interact with their phone. The device connects to the player's smartphone wirelessly using Bluetooth LE. The device notifies the player about events in the game&mdash;such as nearby Pokémon.

An upgraded version known as Pokémon GO Plus+ is due to release July 14th, 2023. 

Features
The Pokémon GO application must be installed on the player's phone in order to use the device. It also allows players to collect Pokémon and Items such as Poké Balls, Berries and even Pokémon Eggs, without having to look at their smartphone.

So far, all available Pokémon GO Plus devices have a red, standard Poké Ball design on them; although the straps of the device can vary in color. The device can be worn on the wrist with a strap or clipped to an article of clothing.

PokéStop alerts
The device will begin to blink blue and vibrate whenever the player is within range of a PokéStop. Pressing the Pokémon GO Plus button will initiate a search for items at the PokéStop. If any items are found, swiping or taping them will add them to the player's inventory. The light will blink multicolor for success and shine red for out of range.

Scanning for PokéStops and Pokémon can be toggled individually. The default setting is set to scan for each simultaneously.

Capturing Pokémon
The Pokémon GO Plus device indicates when a Pokémon is around the wearer by vibrating and flashing its with either a green light, for Pokémon that's been previously captured; or yellow light, for an unregistered Pokémon. The player can then press it to initiate a capture attempt&mdash;it will then flash blue. If the capture is successful it will flash in a rainbow pattern. If the attempt to capture the Pokémon is a failure, it will flash red.
