Problems with new vexOS 1.1.1 update

By “control system” do you mean updated vexos 1.1.1 ?

What was used to control the match ? A competition switch ? Tournament manager with legacy field control (cable into the center connector on your controller) ? or the new field control brain ?

When was this last working, what version of vexos did you have before ?
VEXcode, PROS or something else used for programming ?

Have you read this ?
