1.5 LED Indicator

IBPv1 has four LED indicators. From left to right, the LEDs are OUT, IN, NET, and SYS.

LED	Function	Behavior
OUT	5V output indicator	After IBPv1 joins the LoRaWAN network, after IBPv1 samples the 5V output data and sends an uplink packet, the OUT LED will turn solid red.
IN	12V input indicator	After IBPv1 joins the LoRaWAN network, use an external 12V DC power supply to charge IBPv1. After IBPv1 samples the 12V input data and sends an uplink packet, the IN LED will turn solid red.
NET	Network join indicator	Each time IBPv1 joins the LoRaWAN network successfully, the NET LED will turn solid red for 5 seconds.
SYS	System indicator	The SYS LED will blink green once each time IBPv1 sends an uplink packet or join request packet.

For example, after registering IBPv1 in the LoRaWAN server, switch the device to ON. The device will start up and send join request packets. Each time IBPv1 sends a join request packet, the SYS LED will blink green once. After IBPv1 joins the LoRaWAN network successfully, the NET LED will turn solid red for 5 seconds.

1.6 Installation

IBPv1 can be installed together with the LPS8V2 gateway by using the dedicated two-layer metal bracket. The bracket has round locking posts for fixing IBPv1 and the gateway. Both IBPv1 and LPS8V2 have mounting slots on the bottom side. The device can be fixed to the bracket by aligning the round opening of the slot with the round locking post, placing the device down, and then sliding the device forward or backward until it is locked.

1.6.1 Install IBPv1 on the bracket

Place the IBPv1 on the middle layer of the metal bracket.

Align the round openings of the mounting slots on the bottom of IBPv1 with the round locking posts on the bracket.

Put the IBPv1 down onto the bracket, and then slide the IBPv1 forward or backward slightly. The mounting slots will lock onto the bracket posts and fix the IBPv1 in place.

1.6.2 Install a gateway(LPS8N series gateways) on the bracket

Take the LPS8V2 gateway as an example, place the LPS8V2 gateway on the top layer of the metal bracket.

Align the round openings of the mounting slots on the bottom of the LPS8V2 gateway with the round locking posts on the top layer of the bracket.

Put the LPS8V2 gateway down onto the bracket, and then slide the gateway forward or backward slightly. The mounting slots will lock onto the bracket posts and fix the LPS8V2 gateway on the top layer.

After installation, IBPv1 and the LPS8V2 gateway are fixed together by the bracket. The two devices are separated by the bracket structure, which leaves space between them and helps heat dissipation.

1.6.3 Connect IBPv1 output to LPS8V2 gateway

Use the supplied white Type-C to Type-C adapter cable to connect:

• IBPv1 Out-PWR 5V-2A port
• LPS8V2 gateway PWR 5V-2A port

After this connection, IBPv1 can provide 5V power output to the LPS8V2 gateway.

1.6.4 Charge IBPv1

Use a compatible 12V DC power adapter to connect to the IBPv1 In-PWR 12V-2A port.

When the 12V DC input is connected, IBPv1 can charge its built-in battery and provide power backup for the connected gateway.

2. Configure IBPv1 to connect to LoRaWAN network

2.1 How it works

The IBPv1 is configured as LoRaWAN OTAA Class A mode by default. It has OTAA keys to join LoRaWAN network. To connect a local LoRaWAN network, you need to input the OTAA keys in the LoRaWAN IoT server and press the button to activate the IBPv1. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.

2.2 Quick guide to connect to LoRaWAN server (OTAA)

The following network diagram shows how IBPv1 communicates with a LoRaWAN Network Server, for example TTN v3 LoRaWAN Network . We use the LPS8N as a LoRaWAN gateway in this example and ThingsEye as the IoT platform.

Step 1: Create a device in The Things Stack with the OTAA keys from IBPv1.

Each IBPv1 is shipped with a unique DevEUI, AppEUI, and AppKey. You can find it inside the package of the device. Please keep your registration information in a safe place and don't share with anyone.

You can enter this key in the LoRaWAN Network Server portal.

The following steps describe how to do it with The Things Stack network server portal. Follow the screenshots for correct configuration:

Create an application.

• On the home screen, click the + Add application button.
• On the Create application page, enter an Application ID to identify your application within The Things Stack and provide an Application name . Read https://thethingsindustries.com/docs/integrations/adding-applications for more information on how to do that.
• Click the Create application button.

Add devices to the created Application

• After creating the application, you will be redirected to the Application overview page.
• On the Application overview page, click the + Register end device button.

Enter end device specifics manually.

Add DevEUI and AppKey. Customize a platform ID for the device.

Step 2: Add decoder.

In TTN, user can add a custom payload so it shows friendly reading.

Click this link to get the decoder: https://github.com/dragino/dragino-end-node-decoder/tree/main/

Below is TTN screen shot:

To save the payload formatter, click the ‘Save changes’ button.

After applying the uplink payload formatter, you can see that all uplink payloads shown in the Live Data section are decoded into fields.

Step 3: Activate on IBPv1

Power on the IBPv1 and let it join the LoRaWAN network. After join success, it will start to upload power status data to the server.

2.3 Uplink Payload (FPort=2)

IBPv1 uploads power status data via FPORT=2.

Size(bytes)	2	2	2
Value	Output	Input	Bat_V

Field	Description	Unit
Output	5V output voltage	mV
Input	12V input voltage	mV
Bat_V	Battery voltage	mV

Example:

13 F2 00 00 28 99

Decode:

• Output = 0x13F2 = 5106 mV = 5.106V
• Input = 0x0000 = 0 mV = 0V
• Bat_V = 0x2899 = 10393 mV = 10.393V

In this example, the IBPv1 5V output is about 5.106V, the 12V input is 0V, and the battery voltage is about 10.393V.

2.4 Frequency Plans

The IBPv1 uses OTAA mode and uses the below frequency plans by default (please visit the link below). Each frequency band uses different firmware. You should update the firmware to the corresponding band for your country.
