2.  Operation Mode

2.1  How it work?

Each PB01 is shipped with a worldwide unique set of LoRaWAN OTAA keys. To use PB01 in a LoRaWAN network, user needs to input the OTAA keys in LoRaWAN network server. After this, if PB01 is under this LoRaWAN network coverage, PB01 can join the LoRaWAN network and start to transmit sensor data. The default period for each uplink is 20 minutes.

2.2  How to Activate PB01?

 1.  Open enclosure from below position.

 2.  Insert 2 x AAA LR03 batteries and the node is activated.

 3. Under the above conditions, users can also reactivate the node by long pressing the ACT button.

User can check LED Status to know the working state of PB01.

2.3  Example to join LoRaWAN network

This section shows an example for how to join the TheThingsNetwork LoRaWAN IoT server. Usages with other LoRaWAN IoT servers are of similar procedure.

Assume the LPS8v2 is already set to connect to TTN V3 network . We need to add the PB01 device in TTN V3 portal.  

Step 1:  Create a device in TTN V3 with the OTAA keys from PB01.

Each PB01 is shipped with a sticker with the default DEV EUI as below:

Enter these keys in the LoRaWAN Server portal. Below is TTN V3 screen shot:

Create application.

choose to create the device manually.

Add JoinEUI(AppEUI), DevEUI, AppKey. 

Default mode OTAA 

Step 2:  Use ACT button to activate PB01 and it will auto join to the TTN V3 network. After join success, it will start to upload sensor data to TTN V3 and user can see in the panel.

2.4  Uplink Payload

Uplink payloads include two types: Valid Sensor Value and other status / control command.

• Valid Sensor Value: Use FPORT=2
• Other control command: Use FPORT other than 2.

2.4.1  Uplink FPORT=5, Device Status

Users can  get the Device Status uplink through the downlink command:

Downlink:  0x2601

Uplink the device configures with FPORT=5. 

Example Payload (FPort=5):  

Sensor Model: For PB01, this value is 0x35.

Firmware Version: 0x0100, Means: v1.0.0 version.

Frequency Band:

*0x01: EU868

*0x02: US915

*0x03: IN865

*0x04: AU915

*0x05: KZ865

*0x06: RU864

*0x07: AS923

*0x08: AS923-1

*0x09: AS923-2

*0x0a: AS923-3

Sub-Band: value 0x00 ~ 0x08(only for CN470, AU915,US915. Others are0x00)

BAT: shows the battery voltage for PB01.

Ex1: 0x0C DE = 3294mV

2.4.2  Uplink FPORT=2, Real time sensor value

PB01 will send this uplink after Device Status uplink once join LoRaWAN network successfully. And it will periodically send this uplink. Default interval is 20 minutes and can be changed.

Uplink uses FPORT=2 and every 20 minutes send one uplink by default.

Example in TTN.

Example Payload (FPort=2):   0C EA 03 01 01 11 02 A8

Battery:

Check the battery voltage.

• Ex1: 0x0CEA = 3306mV
• Ex2: 0x0D08 = 3336mV

Sound_ACK & Sound_key:

Key sound and ACK sound are enabled by default.

• Example1: 0x03

          Sound_ACK: (03>>1) & 0x01=1, OPEN.

          Sound_key:  03 & 0x01=1, OPEN.

• Example2: 0x01

          Sound_ACK: (01>>1) & 0x01=0, CLOSE.

          Sound_key:  01 & 0x01=1, OPEN.

Alarm:

Key alarm.

• Ex1: 0x01 & 0x01=1, TRUE.
• Ex2: 0x00 & 0x01=0, FALSE.

Temperature:

• Example1:  0x0111/10=27.3℃
• Example2:  (0xFF0D-65536)/10=-24.3℃

If payload is: FF0D :  (FF0D & 8000 == 1) , temp = (FF0D - 65536)/100 =-24.3℃

（FF0D & 8000：Judge whether the highest bit is 1, when the highest bit is 1, it is negative）

Humidity:

• Humidity:    0x02A8/10=68.0%

2.4.3  Uplink FPORT=3, Datalog sensor value

PB01 stores sensor value and user can retrieve these history value via downlink command. The Datalog sensor value are sent via FPORT=3.

• Each data entry is 11 bytes, to save airtime and battery, PB01 will send max bytes according to the current DR and Frequency bands. 

For example, in US915 band, the max payload for different DR is:

1. DR0: max is 11 bytes so one entry of data
2. DR1: max is 53 bytes so devices will upload 4 entries of data (total 44 bytes)
3. DR2: total payload includes 11 entries of data
4. DR3: total payload includes 22 entries of data.

Notice: PB01 will save 178 set of history data, If device doesn't have any data in the polling time. Device will uplink 11 bytes of 0.

See more info about the Datalog feature.

2.4.4  Decoder in TTN V3

In LoRaWAN protocol, the uplink payload is HEX format, user need to add a payload formatter/decoder in LoRaWAN Server to get human friendly string.

In TTN , add formatter as below: 

2.5 Show data on Datacake

Log in to DATACAKE, copy the API under the account.

Copy and paste the TTN decoder here and save.

Visual widgets please read the DATACAKE documentation.

2.6  Datalog Feature

When user want to retrieve sensor value, he can send a poll command from the IoT platform to ask sensor to send value in the required time slot.

2.6.1  Unix TimeStamp

Unix TimeStamp shows the sampling time of uplink payload. format base on

User can get this time from link:  https://www.epochconverter.com/ :

For example: if the Unix Timestamp we got is hex 0x60137afd, we can convert it to Decimal: 1611889405. and then convert to the time: 2021 – Jan -- 29 Friday 03:03:25 (GMT)
