Functions
•BTT01 is a high precision
temperature data logger. Collect
ambient temperature, use Bluetooth
BLE5.0 broadcast, and realize 24-hour
monitoring through mobile phone APP
or other Bluetooth gateways. Low
power consumption,Standby up to 5
years.
•Temp data is uploaded to the cloud
server through the Gateway, it also help
to realize the accurate location in local
area.
•When BTT01 is used alone,it needs
to match APP to obtain the historical
data and upload to the cloud server. The
location can be located by RSSI signal
strength.
•Application: Logistics management,

4
supply chain, warehouse, terminal and
personal asset management and other
fields
•BTT01 store 180days data with
storing intervals per 5 minutes, Data
content includes date time and
temperature.
•Sync the time on APP for precise
timing from the beginning.
BLE Broadcast Content
（1）beacon MAC address;
（2）Bluetooth beacon signal strength
RSSI value (signal strength when the
scanner finds a beacon).
（3）BLE Version,Battery
voltage,Current Temp, Power up
times,BLE UUID,Alerts status.
（4）Device with name B1 by default；

5
Technical Parameters
Communication method: BLE 5.0
Broadcast power: 8db
Broadcast frequency 5s (customize)
Transmission distance:
open distance up to 500 meters
Factors affecting Battery Life
1. Working Temperature;
2. BLE Connection Frequency;
3. Times of Data transfer;
4. LED indicator on frequency;
5. Transmit Power;
6. Broadcast intervals, battery capacity
7. Note:In order to save power, please
disconnect BLE asap after obtaining
data or modifying parameters.

Turn on / off
•How to turn on:
Device is turned off before it is shipped.
Press the "start" button for four seconds
to turn it on. The blue light blinks five
times, from fast to slowly, extinguish
finally after one minute.
•How to shut down:
When the device is on, press the "stop"
button for four seconds, the red light
flashes 3 times quickly, indicating that
the device is off.
•other:
●When the device is turned on,
press the "start" button and the
blue light will light up, indicating
that the device is working
normally.
●When BTT01 is turned on, the

7
connection is established with the
APP, Blue light will light up once,
indicating that the connection is
successful; when the device is
disconnected from the APP, the red
light will light up once.
●When the device is in an alarm
state (temperature over run, low
battery level, etc.), the red light
flashes quickly.
Note: When the battery voltage is lower
than 2.5V, Blue LED is not on, please
replace the device in time.
BLE APP Application
•APP download
Open BLE on the cellphone,run Beacon
Cloud APP（Download APP from the
website or APP Store）

8
•The broadcast information which
includes temperature, voltage,MAC
address, signal strength of BTT01
device can be previewed and searched
through the Beacon Cloud APP.
•Search the target device by signal
strength or device name on APP.
Text: Input part of MAC address to
select the device.

9
2. RSSI：Signal strength of device. The
device is closer to the mobile phone,
absolute value is smaller. According to
this feature, devices in different ranges
is screened.
Each device address is unique.
•Device List
Broadcasting info of each device,

10
1.Device name：B1
2. MAC：Device address,unique.
3. Signal strength（RSSI）：The closer
between device and mobile phone,the
signal strength is to full.
4. Temp：The battery voltage for current
broadcast time. When battery voltage is
lower than 2.5V, the voltage font will
turn red.
•BLE Connection
Inquire device data details.

11
Historical data query
Inquire the cached temperature data.
After synchronizing data,select the time
period to export the cached
data,synchronize the data to cloud
server. Hong long it takes to get the data
depends on the data amount and the
distance between the device and the
mobile phone.
Device Parameter
Temperature alarm upper and lower
limits, collection intervals, storage
interval, broadcasting interval, device

12
current time.
Device information
Historical data curve: View the detailed
data of a point by zooming with two
fingers, sliding left and right/up and
down.
The data synchronized to the cloud can
be viewed on the platform:
http://beacon.sky200.net
Parameters configuration
Click the Setting icon to modify.
Temp upper and lower limits
Set the upper and lower limits of the
temperature alarm. When the
temperature is too high, the red light of
the device flashes quickly
Sync the time
Sync your phone’s time to device time.
It is recommended to synchronize the
time first after getting device.

13
Basic parameter setting
Set the collection interval, storage
interval, broadcasting interval. It save
180 days data with storage interval per
5mins.
Clear data：
Clear all cached data, restart counting.
•OTA Upgrade：
Synchronize to the latest software
version through OTA (Over the air)
upgrade when software is updated,
