BOLT Modes

Sphero BOLT has 7 modes that help you understand what your robot is doing at any time. Familiarity with these modes ensures proper usage and care.

Off

• This is BOLT’s default mode when it arrives in the box.

• You cannot connect to BOLT until it enters SLEEP mode.

• To transition to SLEEP: place BOLT on the charging cradle and let the light blue animation complete.

• For long-term storage (4+ weeks): charge the battery to approximately 50%, then turn BOLT OFF via the Sphero Edu app or by using the cradle button.

• BOLT in OFF mode won’t be discoverable by the app.

Sleep

• BOLT is awake but not connected to any device.

• This mode allows it to be discovered and connected via Bluetooth to a phone, tablet, or computer.

Cradle Removal

• Activated when BOLT is removed from the charging cradle.

• The robot displays its branding, battery level, and advertising name on the LED matrix.

Play

• Active when BOLT is connected to the Sphero Edu or Sphero Play app.

• In PLAY mode, the LED matrix displays drive screen colors or runs a program.

• Exit PLAY mode by closing the app or selecting “Sleep Robot” in the app.

Charging

• Occurs when BOLT is on the charging cradle with power connected.

• Blinking blue lights on the cradle indicate charging.

• Fully charged BOLTs show a solid blue light.

• Charging time for a depleted BOLT is up to 6 hours, but partial charging is fine, and robots can remain on the cradle after full charge.

Firmware Update

• Activated during firmware updates via the Sphero Edu app.

• LEDs blink orange while updating (about 30 seconds).

• Keep your device close to avoid disconnection.

• Slow blinking red lights indicate an incomplete update. Fully charge BOLT and retry the update if this occurs.

Accidental Disconnect

• Happens if BOLT goes out of Bluetooth range or the app crashes.

• Front/back LEDs turn solid purple.

• BOLT remains discoverable and will automatically return to SLEEP mode after 5 minutes.
