Remote emergency button loses connection

[PetervDooren]

During the german open the emergency button would randomly lose connection to the robot, causing the robot to stop. This was thought to have something to do with other signals which were present during the tournament.

However this issue persists as it has come up multiple times during testing.

When the connection is lost the green light on the remote emergency button flashes. Pressing the button will restore the connection but at this point testing has already been interrupted.

@hvrooy Perhaps you have any ideas what might be causing this issue?
