GrizzLights Horizon – Firmware Update Manual

Firmware releases:

grizzlights_horizon_firmware_1_17_2

Changes since previous release:

• Auto-calibration routine added. Whenever motor homing sequence (initial up and down movement) fails, an auto-calibration attempt is triggered. If that succeeds, new offsets are saved.
• Double click left remote control button to exit LED blink mode.
• Factory calibration steps 2 and 3 swapped: now it’s: 1. gyro calibration, 2. angles calibration, 3. power calibration

grizzlights_horizon_firmware_1_16_10

Changes since previous release:

• Motor initial sequence modified to prevent from incorrectly detecting motor collision on startup.
• Bluetooth connectivity improved: fixing initial connection issue for some units/remote controls
• Remote control connect/reconnect issue fixed (some units were unableto reconnect to bluetooth remote control once conection was lost)
• Lidar initialisation fixed when pointing at the sky (in some cases, the initialisation failed with 3 beeps when pointing up at the sky)

grizzlights_horizon_firmware_1_16_7

Changes since previous release:

• Detect and enter parking mode when wheel is on kickstand or laying on side. Indicated by 2 “ticks” and pulsing halo. In parking mode all buttons are disabled. Switch back to DRL mode when the wheel is lifted up to normal position
• Added protection against saving calibration/data when the EUC is tilted or resting on the kickstand. Data is now saved only when the wheel is stationary and upright.
• Added a 1.5m distance safeguard in LiDAR+Gyro mode to prevent setting the distance based on nearby obstacles.
• Bluetooth connection parameters updated for better stability

• Motor silent mode enabled when not in motion or in daytime modes
• Bluetooth connection parameters modified for better stability and faster initial connection
• Motor homing angle margins increased
