1.  Introduction

1.1  What is the PB01 LoRaWAN Push Button?

The PB01 LoRaWAN Push Button is a wireless LoRaWAN device equipped with a single push button. When the user presses the button, the PB01 sends an uplink to the LoRaWAN Network Server using the long-range LoRaWAN wireless protocol. Additionally, the PB01 measures environment temperature & humidity and periodically uplinks this data to the LoRaWAN Network Server.

The PB01 is powered by 2 x AAA batteries, allowing it to operate for several years.* Users can easily replace the batteries once they are drained.

The PB01 also features a built-in speaker that can produce different sounds when the button is pressed or when a reply (downlink) is received from the Network Server. The speaker can be disabled if the user prefers.

The PB01 is fully compatible with the LoRaWAN v1.0.3 protocol, and works seamlessly with standard LoRaWAN gateways.

* Battery life depends on the frequency of data transmission. Please refer to the battery analyzer for details.

2.  Operation Mode

2.1  How It Works?

Each PB01 is shipped with registration information that can be used to register and activate the device with a LoRaWAN Network Server using Over-The-Air Activation (OTAA), which is the most secure method for activating an end device on a LoRaWAN Network Server. It also supports Activation-By-Personalization (ABP), but this method is not recommended as it is less secure.

After registration, if the PB01 is within the LoRaWAN network's coverage area, it can join the network and start transmitting sensor data to the LoRaWAN Network Server. The default uplink interval is 20 minutes.

2.2  How to turn on PB01?

 1.  Open the enclosure from the bottom.

 2.  Insert 2 x AAA LR03 batteries to turn on the device.

 3. After activating with a LoRaWAN network, you can re-join/restart the device by long pressing the ACT button as shown in the image below.

You can check the LED Status to determine the working state of the 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:

2.3.1 Add PB01 to The Things Stack

PB01 currently supports only manual registartion with The Things Stack.

2.3.1.1 Creating an application

Sign up for a free account with The Things Stack Sandbox if you do not have one yet. Then, create an application as shown in the screenshots below.

2.3.1.2 Adding manually

You can refer to the screenshots below to register your PB01 using The Things Stack's manual registration option.

On The Things Stack console:

• Click Applications.

You will be navigated to the Device overview page.
 

2.3.1.3 Activate the PB01

Press ACT button to activate the PB01. It will then join The Things Stack. Once successfully connected, the device will begin uplinking sensor data to The Things Stack, which can be viewed on the Live data 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

The 'Device Status' uplink is sent by the PB01 as its first uplink after successfully joining a LoRaWAN network. However, you can manually retrieve the device status as an uplink by sending a command as a downlink to the device. The format of the downlink command should be in hexadecimal.

Downlink:  0x2601 

The device uplinks its status via FPort=5, and the payload format is as follows:

The following figure shows the decoded device status payload as displayed on The Things Stack.

For example, if the device status uplink includes the payload,  

Sensor model: 0x35 - for PB01, this value is 0x35.

Firmware version: 0x0100 - value 0x0100 means v1.0.0.

Frequency band: 01 - means EU868. The following are the possible values for other frequency bands.

*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: 0xFF - value 0x00 ~ 0x08 (only for CN470, AU915, US915. Others are 0x00)

BAT: 0x 0CDE - represents the battery voltage for PB01. The values 0x0CDE means 3294 mV = 3.294 V

2.4.2  Uplink FPort=2, Real time sensor values

The PB01 sends real time sensor values after the Device Status uplink. The device will continue to send this uplink periodically. The default interval is 20 minutes, but it can be changed.

This type of uplink uses FPort=2 and, by default, is sent every 20 minutes. The default uplink interval can be changed using AT commands.

The following figure shows the decoded real time sensor values payload as displayed on The Things Stack.

For example, if the real time sensor values uplink includes the payload (FPort=2):   0C EA 03 01 01 11 02 A8

Battery:

Byte 1 and 2: Check the battery voltage.

• Example 1: 0x0CEA = 3306mV
• Example 2: 0x0D08 = 3336mV

Sound_ACK & Sound_key:

Byte 3: Key sound and ACK sound are enabled by default.

• Example1: 0x03

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

          Sound_key:  03 & 0x01=1, OPEN.

• Example 2: 0x01

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

          Sound_key:  01 & 0x01=1, OPEN.

Alarm:

Byte 4: Key alarm.

• Example 1: 0x01 & 0x01=1, TRUE.
• Example 2: 0x00 & 0x01=0, FALSE.

Temperature:

Byte 5 and 6: Temperature.

• Example 1: 0x0111/10=27.3°C
• Example 2: (0xFF0D-65536)/10=-24.3°C

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

(FF0D & 8000：Check whether the highest bit is 1. If the highest bit is 1, the value is negative)

Humidity:

Byte 7 and 8: Humidity

• Humidity: 0x02A8/10=68.0%

2.4.3  Uplink FPort=3, Datalog sensor value

PB01 stores sensor values, and you can retrieve these historical values via a downlink command. The Datalog sensor values are sent via FPort=3.

Each data entry is 11 bytes. To save airtime and battery, the maximum payload size is depending on the current Date Rate and the frequency band.  For example, in US915 band, the maximum payload for different DR is as follows:

1. DR0: maximum payload is 11 bytes. The device will uplink one entry of data.
2. DR1: maximum payload is 53 bytes. The device will upload 4 entries of data (total of 44 bytes)
3. DR2: A payload includes 11 entries of data
4. DR3: A payload includes 22 entries of data.

Note: The PB01 will save 178 sets of historical data. If the device doesn't have any data during the polling time, it will uplink 11 bytes of 0s.

See Datalog feature for more information.

2.4.4  Decoder in TTN V3

In the LoRaWAN protocol, the uplink payload uses HEX format to store data. You need to add a payload formatter or decoder in the LoRaWAN server to extract each field and convert them into readable values.

The following figure shows how to add the uplink payload formatter in The Things Stack. The uplink decoder for PB01 can be found here:  https://github.com/dragino/dragino-end-node-decoder

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

To retrieve a sensor value, you can send a poll command from the network server to request the sensor to send the value within the required time period.

2.6.1  Unix Timestamp

The Unix timestamp indicates the sampling time of the uplink payload, based on the following format:

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

For example, if the Unix timestamp is in HEX format as 0x60137afd, you can convert it to decimal: 1611889405, and then convert it to the time: 2021-Jan-29, Friday, 03:03:25 (GMT).

2.6.2  Poll sensor value

2.6.3  Datalog Uplink payload
