I am a first time FIRST mentor working with an “established” team, but pretty much everyone is a rookie, other mentors included.
We are trying to set up a network so that we can connect the classmate and a development laptop to the CRIO. We tried following the instructions, but they are confusing at best. Sometimes it refers to bridges sometimes routers sometimes radios. This is the equipment we have
CRIO
Gaming bridge (small black box from last year)
classmate netbook
development laptop
Linksys AP/Bridge
I’ve read a few other threads with similar questions, and think I have a good handle, but just want to clarify because I know I’ll have trouble otherwise.
So it seems we no longer need the small black gaming bridge from last year. So we’ll put the linksys into AP mode, set the ssid to our team number, set the WPA key to ####WPAKEY. The linksys device in AP mode connects directly to the CRIO via an ethernet cable(??). Then the classmate and development laptop connect to the AP via wireless connections. (??)
Then we’ll have:
CRIO 10.XX.XX.2
classmate 10.XX.XX.5
development laptop 10.XX.XX.101
What about default gateways and all that? subnet masks?
We are still working on getting ours to talk, but here’s what I understand so far. Anyone please correct me if I’m wrong.
The small black gaming adapter on the robot from last year goes away.
The Linksys router on the drivers’s station, that was connected to the Classmate goes away.
The D-link access point / bridge (DAP-1522) is used in the robot, the classmate connects wirelessly to it. The switch should be in “Bridge” mode for competition, and "AP (access point) for programming. Follow the instructions in the control system docs for setting it up.
The development laptop needs to have its wireless address set to an address like 10.x.y.50, or turn on DHCP in the d-link to start handing out addresses starting at 10.x.y.10. So it stays above the addresses use for the CRIO, d-link, and classmate.
We are working on getting Windriver workbench to see the CRIO. It still won’t see it, even tethered. The laptop can ping it. Anyone have any helpful ideas on that?
Make sure you have imaged the cRIO and selected C++ as the language. Otherwise the debugging service on the cRIO will not be started and Workbench will not have anything to connect to.
The default subnet is 255.0.0.0 also for the non clasmate i belive the last octet should be .6 so it should be 10.xx.xx.6 with a subnet of 255.0.0.0 as far as connectivity goes if you are tethering the connection (running cable from the robot alot of teams leave the wireless on on the classmate and dont change the ips for it (just what i have noticed, i have done it myself.)
If we are doin wireless connection on a non classmate laptop should the adressing scheme :
Ip: 10.xx.xx.6
subnet mask: 255.0.0.0
default gate: 10.xx.xx.2 (cRIO)
