What do the LED colors on the control switch mean?

EX and MX 1.2

• blue — charging
• green — on, ready to ride
• blinking green — neutral, throttle disabled (press − to get solid green)
• red — not ready to ride yet
• blinking magenta — update ready
• purple — crawl backward (hold the lower button)
• yellow — crawl forward (hold the upper button)

First MX: dark blue — charging, light blue — charging with cooling running, red — lights up before switching off, magenta — update.

From the chat: blinking red on a switched-off bike means sleep mode.
