Post Bluetooth connection to multiple devices
Hi,

I'm trying to connect my brick to both my phone (or laptop haven't made up my mind yet) and another brick. Unfortunatelly when I'm trying to connect the second device, doesn't matter whether it's another brick or phone, the other connection gets disconnected or I get the "line busy" message.

Any ideas what might be the reason for that? And how to solve it?

At a guess, I'd say that the phone needs to be the "master" and the NXT's as "slaves". That would mean that the phone has to receive and send the messages that the NXTs would normally be sending directly to one another.

My best guess is that the NXT can only handle 3 NXT device, and only 1 Other device at one time. I really don't know. :oops:

I don't think you can daisy chain NXTs... Although you can do that with EV3s ;)
But what you can do is connect both to a computer :)

Well, there was a comparison article between NXTs and EV3s which mentioned that you couldn't daisy chain NXTs... I think it's because you need to have capabilities to filter messages/packets and it just complicates things.

Because they aren't designed for it. The EV3 has USB host, but the NXT doesn't.

You can make a large wired NXT network using RS485 though.
