4.3 Battery consumption
Here we have described battery consumptions in some common configurations which refer to different use cases.
You can refer to below table to create the use case and estimate battery lifetime.

Battery consumptions – With motion sensor

Adv type| Tx power| Advertising interval| Consumption (uA)| **Lifetime***
Tag info| 0dBm| 100ms| 152.5uA| 1.2 months
500ms| 36.2uA| 5.5 months
1000ms| 22.6uA| 8.5 months
2000ms| 15.5uA| 12.5 months
5000ms| 11.6uA| 17 months
10000ms| 10.3uA| 19 months
Sleep mode (No advertising)| 6.4uA| /
Power off mode| 3.7uA| /

Battery consumptions – Without motion sensor

Adv type| Tx power| Advertising interval| Consumption (uA)| **Lifetime***
Tag info| 0dBm| 100ms| 135.6uA| 1.5 months
500ms| 31.8uA| 6 months
1000ms| 17.5uA| 11 months
2000ms| 9.7uA| 20 months
5000ms| 5.6uA| 35 months
10000ms| 4.1uA| 48 months
Sleep mode (No advertising)| 2.9uA| /
Power off mode| 2.7uA| /

Table 4: Battery consumption – Without motion sensor
To enhance the understanding of battery lifespan, here we described some practical scenarios for reference.

Battery consumptions – Practical scenarios

Table 5: Battery consumption – Practical scenarios

Scenario 1: Asset presence detection – Office/Museum

Purpose: In some working scenarios, it will only need to report the asset status every 1 hour or even longer, to just confirm the assets are in there or anti-theft purpose.
Configuration:
a) Broadcasting 10s (in case scanning window missed) every 8 hours.
b) Adv interval 1000ms during 10s adv durations.
c) Motion sensor is not necessary.
Lifespan estimation:
a) Adv period (average) – 16.7uA
b) Sleep period (average) – 3.7uA

Whole period (average) – 3.8uA
Lifespan estimation – 4 years
220(mAh)80%(effective factor)80%(self-discharge factor)/0.0038(mA)/24(hours)/30(days)/12(months) ≈ 4 years

Scenario 2: Movement-based dynamic tracking (RTLS) – Warehouse/Healthcare
Purpose: In some working scenarios, there will need dynamic advertising mechanism to apply into the real-time positioning. For instance, combination with high frequency report during motion period and low frequency report during static period. It will guarantee the positioning accuracy and decrease battery consumptions.
Configuration:
a) Adv interval in motion status – 1000ms.
b) Adv interval in static status – 5mins. (Broadcasting 10s every 5mins, and 1000ms interval during 10s adv durations)
c) Motion sensor is necessary.
d) 4 hours in moving per day.
Lifespan estimation:
a) Motion period (average) – 22.6uA
b) Static period (average) – 6.9uA (Broadcasting – 22.6uA, Sleep – 6.4uA)

Whole period (average) – 9.5uA Calculation: (422.6uA+209.5uA)/24+
Lifespan estimation – 1.7 years
220(mAh)80%(effective factor)*80%(self-discharge factor)/0.0095(mA)/24(hours)/30(days)/12(months) ≈ 1.7 years

*The lifespan here refers to expected life cycle under the standard 25°C usage conditions.

4.4 LED descriptions
Here we have described the LED response status in some common situations.

LED response status

Scenarios| LED color| Response
LED response status

Power ON| Red| Blinking for 2 seconds
Device connect| Red| Blinking twice
Power OFF| Red| Solid for 2 seconds
Factory restore| Red| Solid for 2 seconds and then device reboot
DFU upgrade| Red| Blinking during DFU upgrade, and solid for 2 seconds after finished, then device reboot
Low battery| Red| Blinking twice every 10 seconds
LED notification| Red| Blinking once — Motion triggered

Basic instructions

5.1 How to wear/install M4?

Figure 2: How to wear/install M4 Lite Tag?
5.2 How to power ON M4?
To minimize the size of product as much as possible and suitable for various scenarios, as well to avoid intentional power off actions, the M4 Lite Tag has no reserved mechanical button design. Therefore, we have added “mylar film” to simply power on device.

Power ON: Take the “mylar film” out, and Red LED will keep blinking for 2 seconds to power on.

5.3 How to restore factory settings?
There have two ways to restore factory settings.

Software reset: Connect with M4 device through “MK Tag” APP and then execute “Settings >> Reset Beacon” operations to finish the software reset.
Hardware reset:

Remove the cover and the battery.
Put the battery in until you see the LED blinking for 2 seconds. This LED blinking means that the battery is connected successfully.
When the LED blinking finishes, put the battery in again within 5 seconds, and then repeat the process four more times, removing and replacing the battery. You should see a LED blinking each time you put the battery in, for a total of five blinking. The fifth blinking is different from the previous four and indicates that the device is factory reset successfully.
1st– 4th: LED blinking for 2s. This indicates the battery is connected successfully.
5th : LED keep solid for 2s. This indicates the device is factory reset successfully.
Replace the cover by aligning the battery room and press down on the cover.
