You need a Netgear WNA1100, it's the only one currently supported. They're about 17 usd on Amazon.

Thanks. Just ordered two. Did you just ssh into the console? What's the default root password? Do you know what flavor of Linux it is using? Ubuntu? Debian? Fedora?

pfff, ssh, no way! Telnet, man! username: root, password: <empty>



It's using an older build of Angstrom.

Then Telnet it is. Thanks. Would EV3 mind if I change the root password? Just don't want to break it if I do.

You can't, not with the standard firmware anyway. It's CRAMFS, which is RO. There are parts that are RW, but the entire OS filesystem partition is immutable.

I have an image that I use to boot the EV3 from SD card but it does not start up the LEGO VM. It's much more hackable

Do you have a 2GB SD card? I could probably cobble something together for you that you can boot your EV3 with and play a little more and still use the NI stuff.

I have a 16GB micro SD card. Would that work? I hope it's not too big. Some FS may not support that size. BTW, when I have the SD card plugged in, the EV3 brick hung and never booted up. I had to pull the battery to restart it. Was it trying to boot from it? Or does it not recognize the FS? What kind of FS does EV3 expect the SD card to be formatted? Would it support ExFAT or FAT32?

It may have had a boot sector on it. You need to format it completely I've used a 16GB card with it as well, shouldn't matter. For normal use, the card has to be FAT32 or exFAT, I believe. If it's an SD card that will contain an operating system, it'll be a bit different with a couple of partitions on it.

Ah, with it formatted as FAT32, EV3 booted up fine. But how do I access this storage? I looked through the menus and did not see anything about SD storage. I was expecting an extra menu item will show up for this extra storage. The folder tab still just showed the BrkProg_SAVE folder as before.

If it is mounted properly (which is an automatic thing), it will appear in the menu. If it doesn't appear, something went wrong. Not a whole lot of info, unless you're on the console.

Alright. There is something wrong with that card. It doesn't even consistently showing up on my laptop. Time to buy a new one
Will the EV3 take a 32GB micro SDHC card?

No idea, I have not tested that. I believe it's SDHC, though, so it should, theoretically, work

I have 2 questions:
1. Do the old NXT direct commands still work with ev3?
2. Is there an api, sdk and documentation for controlling the ev3 from ios or android?

I don't know what you meant by direct command but RobotC does not support EV3 yet. EV3 is supposed to work with android and ios but I don't know the details.

No, they're completely different.

No, at least not yet.

Hi

I originally started this long thread ... .
Now that I can order in few days the EV3 I am getting back to some basic questions (As I said I am new to that area but have s/w and h/w background).

1. I guess the the version I will be able to order in few days is the retail one. Correct?

2. Do I need to buy a special software to operate it? I don't want to even start using the GUI interface I saw for the previous NXT. What s/w does it use? what comes with it?

3. I saw all your linux discussion above and I am a bit worried . I don't want to get into that. I just want a robot with an interface that I can use to program (like in C) and build my own machines with my own software. Is that possible ? Will the RobotC enable that or I must be an expert in linux? Can you please make some order for me?

Thanks!,
Amit
