When trying to get our new keys to pair the lights on the controller and robot were all red. We have updated the master code on the controller and the robot. We can drive while they are both tethered together but won’t drive with the two keys.
Looks like that was just released in the last couple of days, changelog says “security enhancements”, I imagine now that V4.23 in the cortex/joystick probably needs to see V1.46 in the keys if what I think was changed was in fact changed.
So I don’t have time right now to check this, but as ROBOTC V4.26 and EasyC are still shipping with the V4.22 master firmware, if new keys are now on V1.46 they may not be compatible.
You need 2 Tools to do the Updates. The Tool for Updating the Whites Keys is called the “VEXnet Key 2.0 Firmware Upgrade Utility. The Tool for Updating the Master Code is called " VEXnet Firmware Upgrade Utility”.
