No, it's a different interference. Unlike analogue 27 MHz, you can't hijack control of another hub, but instead useful range will decrease. I have a Wi-Fi-controlled drone (2.4 GHz), which flew very well at an event of my LUG during set-up. But, with the crowded event, full of people and their phones with Wi-Fi and Bluetooth activated, I quickly gave up on having the drone fly more than about 2 metres away.

I'd bet it's cheaper due to easily available off-the-shelf components, something that didn't happen as much in 2007 when PF appeared, and the lack of certification fees. No, because there are a lot of different protocols that use 2.4 GHz. It's the same reason why you usually can't use an IR TV remote of one brand to control a TV of another brand.

Cool, thanks! Indeed there doesn't seem to be any photodiode, required to receive IR, at the top of the board. It doesn't require line-of-sight and is immune to sunlight, but isn't as cheap, can be subjected to other kinds of interference (2.4 GHz is also used by Bluetooth, Wi-Fi, drones, cordless phones, microwaves, etc.), and in theory the manufacturer needs certification for compliance.

Can you take a screwdriver to the transmitter or receiver? I think everyone here would like to take a peek inside.

Under direct sunlight, there's really nothing much IR can do. Does the Chinese system really use IR, or is it radio?

To test your controller's modes, you should use BC2's "Controller" screen, not "Device".- 1,316 replies

If it doesn't have a hardware selector to switch between iOS and Android, I don't know what button combinations to use. Its product page has a downloadable manual, maybe it shows there how to switch?- 1,316 replies

I have an iPega 9055, which works well with BC2 and all the Android devices I tested it with. It has an "iOS/Android" switch, which I keep set to "Android"; does yours have something like that, or a button combination to switch modes?- 1,316 replies

42113 Reconstruction Guide
AVCampos replied to Ngoc Nguyen's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Ah no, that's unacceptable! That colour scheme is totally military! Bone white and blood red? Won't somebody please think of the children?! (just kidding, the colours are very nice and I just wanted to send some barbs towards TLG) -

I'm still not sure if the Prime hub (used in 51515 and 45678) uses standard Bluetooth instead of BLE like the other PUp hubs.- 1,316 replies

Yes, and people still complained about it. Also about how simplistic the drivetrain was, with each motor practically directly connected to its track. People nowadays see it in a more positive light (just like they do with almost all sets), and I'm sure the 42131 will be the same when the time comes for a new Technic bulldozer.
