Why do tamagotchis still not use Bluetooth instead of IR?

[Ourworld]

Perhaps I'm just dumb, but I wouldn't think that giving the tamagotchis bluetooth would be impossible. It certainly would probably be the best option as of now, with basically all computers AND phones using bluetooth but not the old InfraRed. It just confuses me a bit when I think about it. I'm a bit lazy, and don't have much money, so the thought of having to buy an old phone or a dongle, kind of bothers me.

Does anyone know why this is? No bluetooth I mean . Perhaps there's a technical reason that I don't understand. I am pretty clueless when it comes to how the tamagotchis are made anyway. But since we are so far ahead now with robots and other cool things I just can't wrap my head around this one.

Bluetooth would increase the price and decrease battery life.

Not necessarily. Low power Bluetooth can be implemented rather cheaply into a computer; you can buy a raspberry pi, a credit card sized computer with a 1.2GHz 64bit quad core prossessor and 1gb of ram with integrated Bluetooth 4.1 for about 40 usd.

A 'standard' Bluetooth connection would be cheap, but Bandai doesn't use much non proprietary stuff.
