Here, you can see all devices connected to nucleus across all organizations.
If you are having issues with finding a robot on the facilitator device, you can check this monitor and make sure that it’s ready to connect. It should have a Session ID of 00000000-0000-0000-0000-000000000000, and the line of the robot should be green with the websocket status of “Open”.
If you are having issues with finding a student device on the facilitator device, you can check this monitor and make sure that it’s ready to connect. It should have a Session ID of 00000000-0000-0000-0000-000000000000, and the line of the robot should be green with the websocket status of “Open”. The Organization ID should be the same as the facilitator ID.
Possible Issues with robots or students not showing up.
1. Student device or Robot isn’t anywhere on the list.
a. The device or robot needs to be connecting to the internet and updated. Try updating and rebooting.
Student device or Robot have an active session ID
That device is currently still in a session with nucleus. Restart the device. If this doesn’t fix it, it should get kicked out after a maximum of ~15 minutes(This can rarely happen with the robot).
Once you see 00000000-0000-0000-0000-000000000000 for the sessionID it’s ready to connect.
Student device has a different organizationID than the facilitator device
Use the hidden menu on the student device, and unpair the tablet
Use add new student on the facilitator tablet, and go through the registration/repairing process again.
I’ve done all the above, but the robot still isn’t showing up!!!
Check how the robot is current setup in RK Central, make sure the facilitator is set to itenerant if it’s supposed be. Compare with other working orgs if you’re not sure how to set it up.
