2. Operation Mode
2.1 How does it work?
Each PB05-L is shipped with a unique set of LoRaWAN registration information, including DevEUI, AppEUI, and AppKey. To use the PB05-L in a LoRaWAN network, the user must register these EUIs and keys in advance to enable OTAA activation of the device in the LoRaWAN network server.
Once the device is powered on and within the network’s coverage, it will automatically join and start transmitting sensor data. By default, it sends an uplink every 20 minutes.
2.2 How to Activate PB05-L?
1. Open the enclosure from the bottom as shown in the image below.
2. Insert 2 x AA LR6 batteries. Make sure to insert them in the correct direction.
3. Activate the device by pressing and holding (long press) the ACT button.
You can check LED Status to determine the working state of the PB05-L.
2.3 Joining with a LoRaWAN network server
This section shows an example of how to join The Things Stack LoRaWAN network server. Registering with other LoRaWAN network servers may also follow a similar procedure.
Assume the LPS8v2 is already set to connect to TTN V3 network . We need to add the PB05-L device in TTN V3 portal.
The following network diagram shows that the PB05-L is connected to a LoRaWAN Network Server. The network server supports end-to-end data communication between the PB05-L and the application server. You can use any public LoRaWAN Network Server to register your device, or you can set up your own private LoRaWAN Network Server. The Things Stack (both free and paid) and ChirpStack are some of the popular LoRaWAN Network Servers available for use.
2.3.1 Joining with The Things Stack
Step 1: Create a device in TTN V3 with the OTAA keys from PB05-L.
Each PB05-L 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 the application.
Add devices to the created Application.
Enter end device specifics manually.
Step 2: Add decoder
In TTN, user can add a custom payload so it shows friendly reading.
Click this link to get the decoder: PB05-L decoder.
Below is TTN screen shot:
Step 3: Use ACT button to activate PB05-L 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 Commands.
- Valid Sensor Value: Use FPort=2
- Other Status / Control Commands: Use an FPort other than 2.
2.4.1 Uplink FPORT=5, Device Status
You can get the Device Status uplink through the downlink command:
Downlink: 0x2601
The device uplinks the status using FPort=5.

Poll Message Flag: 1: This message is a poll message reply.
- Each data entry is 11 bytes, to save airtime and battery, PB05-L will send max bytes according to the current DR and Frequency bands.
For example, in US915 band, the max payload for different DR is:
- DR0: max is 11 bytes so one entry of data
- DR1: max is 53 bytes so devices will upload 4 entries of data (total 44 bytes)
- DR2: total payload includes 11 entries of data
- DR3: total payload includes 22 entries of data.
If user sends below downlink command: 
Where : Start time: 6722DD98 = time 24/10/31 Thursday 01:30:00
Stop time: 672300C0 = time 24/10/31 Thursday 04:00:00
PB05-L will uplink this payload:

See more info about the Datalog feature.
2.5 Show data on Datacake
Datacake IoT platform provides a human friendly interface to show the sensor data in charts, once we have sensor data in TTN V3, we can use Datacake to connect to TTN V3 and see the data in Datacake. Below are the steps:
Step 1: Be sure that your device is programmed and properly connected to the LoRaWAN network.
Step 2: Configure your Application to forward data to Datacake you will need to add integration. Go to TTN V3 Console --> Applications --> Integrations --> Add Integrations.
1. Add Datacake:
2. Select default key as Access Key:
3. In Datacake console (https://datacake.co/) , add PB05-L:
Please refer to the figure below.
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 0x6722DD98, we can convert it to Decimal: 1730338200. and then convert to the time: 2024/10/31 Thursday 01:30:00 (GMT).
2.6.2 Set Device Time
There are two ways to set device's time:
1. Through LoRaWAN MAC Command (Default settings)
User need to set AT+SYNCMOD=1 to enable sync time via MAC command.
Once PB05-L Joined LoRaWAN network, it will send the MAC command (DeviceTimeReq) and the server will reply with (DeviceTimeAns) to send the current time to PB05-L. If PB05-L fails to get the
time from the server, PB05-L will use the internal time and wait for next time request (AT+SYNCTDC to set the time request period, default is 10 days).
Note: LoRaWAN Server need to support LoRaWAN v1.0.3(MAC v1.0.3) or higher to support this MAC command feature, Chirpstack,TTN V3 v3 and loriot support but TTN V3 v2 doesn't support. If server doesn't support this command, it will through away uplink packet with this command, so user will lose the packet with time request for TTN V3 v2 if SYNCMOD=1.
2. Manually Set Time
User needs to set AT+SYNCMOD=0 to manual time, otherwise, the user set time will be overwritten by the time set by the server.
2.6.3 Poll sensor value
User can poll sensor value based on timestamps from the server.
Below is the downlink command.
| 1byte | 4bytes | 4bytes | 1byte |
| 31 | Timestamp start | Timestamp end | Uplink Interval |
Timestamp start and Timestamp end use Unix TimeStamp format as mentioned above. Devices will reply with all data log during this time period, use the uplink interval.
For example, downlink command
Is to check 2024/10/31 01:30:00 to 2020/12/1 04:00:00's data
Uplink Internal =5s, means PB05-L will send one packet every 5s. range 5~255s.
2.6.4 Datalog Uplink payload
See Uplink FPORT=3, Datalog sensor value
2.7 Buttons
- ACT button
Long press the ACT button to reset the device and allow it to join network again.
- Alarm buttons
When you press an alarm button, the PB05-L immediately uplinks data. The alarm flag is set to 'TRUE,' and the corresponding button status is 'Yes'.
2.8 LED Indicators
The PB05-L has a tri-color LED for easily indicating different stages.
Hold the ACT button until the green light turns on to reset the device. The green LED will flash as the node restarts, the blue LED will flash once when requesting network access, and the green LED will remain on for 5 seconds after successful network access.
In a normal working state:
- When the node restarts, hold the ACT button until the GREEN LED lights up. The GREEN LED will flash as the node restarts.
- The BLUE LED will flash once upon requesting network access.
- The GREEN LED will remain on for 5 seconds after successful network access.
During OTAA Join:
- For each Join Request uplink, the GREEN LED will blink once.
- Once the Join is successful, the GREEN LED will remain on for 5 seconds.
- After joining, for each uplink, either the BLUE or GREEN LED will blink once.
Alarm Button Press:
- When an alarm button is pressed, the RED LED will flash until the node receives an ACK from the platform.
- Once the ACK is received, the BLUE LED will stay on for 5 seconds.
2.9 Buzzer
The PB05 has a button sound and an ACK sound, both of which users can turn on or off using AT+SOUND.
- Button sound is the tone played by the node after an alarm button is pressed.
You can use AT+OPTION to set different button sounds. - ACK sound is the notification tone played when the node receives an ACK.
