Servos, cameras, and inverting limit switches

44001 isn't an error, it's just an informational message.
It's telling you the other devices that it is able to connect to.

10.xx.yy.5 should be your Driver Station PC's Ethernet adapter.
10.xx.yy.9 should be your Driver Station PC's wireless adapter.

These can be set automatically when the Driver station is started.

1. Go to the Setup tab
2. Click on "Choose NIC..."
3. See if both the wireless and wired networks are NOT set to manual.

Get the Ethernet connection working again, before working on the wireless connection.

Your wireless connection problem can be due to several things, in addition to an incorrect IP address/netmask.

• If you haven't used wireless since your last competition, then the robot bridge probably still still has the playing field security set. There is a Bridge Configuration Tool we use to setup the robot bridge properly for home use.
• Check to see if your PC can see the robot network on the Windows wireless connection list. You may have to manually connect to it if you haven't chosen to Connect automatically.

I think I'm going to have to do this, but I just want to make sure it won't screw it up for future competitions, or their is something you can do to change it for competitions in the future.

I can see the network, but attempting to connect to it doesn't work.

It won't mess up the bridge for future competition use, so don't worry about that.
The Bridge Configuration tool actually gets run at each competition before you can connect to the playing field. It gives each team a unique security code.
That security code left over from your last competition is why you can see the wireless network, but it won't let you connect. Your PC doesn't know the security code.

One other thing to check is that the robot bridge is switched to one of the AP modes.

How do I check that? I got it working through ethernet with the configuration, but it doesn't work with wireless.

[Mark McLeod]

There is a manual switch on the back of the robot's DLink bridge.
Depending on the model you are using, the switch will be marked differently.

The Rev A switch will be marked "Bridge", "Auto", "AP"
The Rev B switch will be marked "Bridge", AP 2.4GHz", "AP 5GHz"

You want either "AP" or "AP 2.4GHz"
Don't choose "AP 5GHz" unless you know that you're using a laptop that's 5GHz capable. The FIRST issued Classmates only support 2.4GHz.

Got that right. What else could be causing a problem with wireless but not ethernet?

What I'd do next is connect an ethernet cable between PC and DLink. Open the web page on the DLink -- the FIRST directions tell you how to do this if you are having problems.

Then check what SSID the DLink will use. Team number is what is suggested I believe. Check the security settings and perhaps turn them off if they may be the issue.

On that laptop or on another wireless enabled laptop verify that you can see a wifi network with that SSID name and attempt to Connect to it. For the laptops used in FIRST, you may want to set them to auto-connect to it.

If you get this working, the programming tools and DS will likely work. If not, then it is an IP issue.

I did a quick google search and a computer search, Not sure what you mean by FIRST directions. I also tried to find how to open a web page of a DLink. Couldn't find anything though.

I can't connect to the network except in the driver station, if that matters.

Also I'm having another problem similar to the true/false one, I'm changing the speed of a motor and it doesn't change how fast the motor actually moves. How does changing the speed of a motor work in the programming?

[Mark McLeod]

Use a web browser and type 10.46.92.1
That browses to the DLink.
The login is admin and the password is blank.

Find "Setup" then "wireless" and look at the settings for wireless.

The directions are on page 23, though I was wrong, they don't tell you to log in. They tell you to use the config utility.

Ok, I figured out how to get to the Dlink. However Security settings are "none", does wireless type matter? Wireless is set to always.

Also out of curiosity if you are connected to a router how do you find the IP? I know what it is for this, but for general purpose.

[Mark McLeod]

To see the devices connected to your laptop, open a Windows command window (go to Start and type "cmd" into the search at the bottom) and type:

arp -av

The wireless AP will show up connected to your PC's wireless adaptor.


Wireless settings should be:

• Enable Wireless = checked
• Wireless network name = 4692 (but can be anything)
• Security Mode = none
• Wi-Fi Protected Setup Enabled = NOT checked
• Wireless MAC Cloning = NOT checked

Network settings should be:

• LAN Connection Type = Static IP
• IPv4 Address = 10.46.92.1
• Subnet Mask = 255.0.0.0
