LED & Buzzer Behavior
The BoxLock device provides visual feedback to the user via RED, GREEN, PURPLE and BLUE LEDs. The color of the illuminated LED along with the illumination duration and frequency determine the meaning of the visual response.
The BoxLock device provides audio feedback to the user via a buzzer. The BEEP duration, number of BEEPs, and pause interval between BEEPs determine the meaning of the audio feedback.
Heartbeat
The BoxLock device presents a BLUE LED blink every 5 seconds for a duration of 200 milliseconds to indicate an active BoxLock device when the device is not connected to a USB charging source.
Charging State
The BoxLock device presents a solid GREEN LED when the device is connected to a USB charging source to indicate a fully charged device.
The BoxLock device presents a solid YELLOW/ORANGE LED when the device is connected to a USB charging source to indicate a charging device that is not fully charged. All other LEDs are turned OFF .
When the USB-plugged BoxLock device is unplugged from a charging source, the RED and GREEN LEDs are turned OFF .
Sleep State
When the device is idle for 30 seconds and is NOT connected to a USB charging source, the device will enter a deep sleep state to conserve battery until the Main Button is pressed.
Immediately prior to entering deep sleep,
- The device turns the Heartbeat OFF
- The device turns all LEDs OFF
- The device blinks the GREEN LED 3 times with a duration of 100 milliseconds each and a 200-millisecond interval between blinks.
Updating Firmware
When an Firmware Update task is initiated,
- The device turns the Heartbeat OFF
- The device presents a solid PURPLE LED
- The device ensures the RED and GREEN LEDs are turned OFF
When the Firmware Update task is actively downloading,
- The device toggles the PURPLE LED ON and OFF each time 25K bytes are downloaded
When the Firmware Update task completes successfully,
- The device ensures the heartbeat is turned OFF
- The device blinks the PURPLE LED 5 times with an ON duration of 100 milliseconds and an OFF duration of 200 milliseconds
- The device precedes each PURPLE LED blink with a 100-millisecond buzzer BEEP
- The device Restarts
When the Firmware Update task does NOT complete successfully,
- The device buzzer BEEPs for a 1 second duration
- The device presents 5 RED LED blinks with an ON duration of 100 milliseconds and an OFF duration of 200 milliseconds
- The device precedes each RED LED blink with a 100-millisecond buzzer BEEP
- The device turns all LEDs OFF
- The device initiates the Heartbeat
