A client wants me to prototype a game interaction with an external device using Bluetooth. I need a device to test the prototype with until they figure out what the actual device will be.
The game is being developed in Unity for Android/iOS. I've found a plugin that lets Unity talk to Bluetooth peripherals, now I just need a peripheral to test with until they figure out what the actual device will be.
Requirements:
A Bluetooth LE peripheral
Has some way of displaying state, preferably an LED
