We would like to implement this strategy. We have about 10 students on our Programming Team this year, using 4 Laptop's (with wifi). However, it is planned that only 1 of those Laptop's (besides the Classmate) will be connected directly to the Robot (we are calling it our Production Computer). The other computers are going to be doing some autonomous development, documentation, that kind of thing, so they don't necessarily have to connect to the Robot. However, since we have so many computers we are using another computer for our SVN Repository. See the attached document for details.

The easy way to do this is to have 2 separate wireless networks, 1 for the robot itself (including the classmate, Production Computer and D-Link) and our other wireless network for development, and then switch the Production Computer's wifi network to the Development network when code has to be passed down from the SVN Server. I feel that is somewhat of a kludge and can lead to problems.

The hard way (and what this document and quoted post refers to) is to have everything on one network and have the D-Link and Linksys in the same configuration as last year (although the D-Link and Linksys configuration is the gray area for me there).

I'm not positive I am interpreting the drawing correctly, but if gives me names for things.

What I think you want to do is to setup the linsys router to be an AP and have the ports and wifi SSID that the laptops can join. Setup the D-Link to be in bridge mode from the linksys router. The cRIO will be 10.te.am.2, the classmate will actually join the network hosted by the linksys, but synce it is 10.te.am.05, it will route to the robot. The other laptops can be setup on pretty much any 10.xx.yy.zz subnet, but it may be most convenient to set them all to 10.te.am.100+. You could even setup the Linksys to serve those up via DHCP. I'm not sure if the SVN server is something you administer, but either way, it should be reachable.

The DAP-1522 can either be a AP or Bridge, but not both. You diagram will work fine except your classmate would need to go through the router.

For those of you who have the DAP running already, how does the classmate handle connecting to the DAP in AP mode? Does it have any trouble with the on/off cycles that happen on the robot?

[Greg McKaskle]

Unless changed, the win7 profile for the laptop should reference the SSID of robot dlink, and it should be set to auto-connect. If for some reason, you start doing things manually, this is a step you may want to include.

To bad the Radio Instructions have you change the SSID in AP mode.

The trick to set the SSID with the DAP-1522 in BRIDGE mode is to select SETUP and then WIZARD in the DAP-1522 web interface. Through the wizard interface you can set the SSID to your team number. Otherwise you need to set the SSID in AP mode, then switch back to BRIDGE mode.

So much for remotely coordinated bug fixes in code and docs.

Since most DSes will only be used for one team, it shouldn't matter much once the profile on the DS is updated.

As a note, for competition you must set the DAP into the bridge mode.
As a special highlight, you may now tether through the DAP when it is connected. No more disconnecting the radio from the Crio to program and then forgetting to plug it back in on the field. I saw a demonstration (over the weekend) of the new setup tool teams will be using to set WPA encryption at events. It is very good and simple to use. Teams will need to bring their DAP to the setup kiosk (laptop) at each event to set the key. On screen instructions are provided during setup to help you walk right through it.

Wait, what?

Are you saying that we will be permitted to leave the DAP powered up when running the robot in the pit?

[Al Skierkiewicz]

The decision on that is still being evaluated, please standby for official declaration on wireless use in the pits at events.
