2. Configure BH01-LB to connect to LoRaWAN network

2.1 How it works

BH01-LB 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 BH01-LB.It will automatically join the network via OTAA and start scanning nearby Bluetooth devices, sending the scanned device information to the network.The default uplink interval is 20 minutes.

2.2 ​Quick guide to connect to LoRaWAN server (OTAA)

Following is an example for how to join the TTN v3 LoRaWAN Network. Below is the network structure; we use the LPS8v2  as a LoRaWAN gateway in this example. 

The LPS8v2 is already set to connected to TTN network , so what we need to now is configure the TTN server.

Step 1: Create a device in TTN with the OTAA keys from BH01-LB.

Each BH01-LB is shipped with a sticker with the default device EUI as below:

You can enter this key in the LoRaWAN Server portal. Below is TTN screen shot:

Register the device

Add APP EUI and DEV EUI

Add APP EUI in the application

Add APP KEY

Step 2: Activate BH01-LB

Press the button for 5 seconds to activate the BH01-LB.

Green led will fast blink 5 times, device will enter OTA mode for 3 seconds. And then start to JOIN LoRaWAN network. Green led will solidly turn on for 5 seconds after joined in network.

After join success, it will start to upload messages to TTN and you can see the messages in the panel.

2.3.2 Working Modes & Sensor Data. Uplink via FPORT=2

BH01-LB has different working mode for the connections of different type of sensors. This section describes these modes. Use can use the AT Command:

AT+MODEL=abcdefgh to set BH01-LB to different working modes.

For example:

AT+MODEL=030500190b0004ff4c000215011223344556 (turn on scanning Bluetooth ibeacon beacons)

Parameter a = 0x03: Set the scanning mode to Bluetooth ibeacon beacons.

Parameter b = 0x05: Set the intercepted data length to 5.

Parameter c = 0x00: Set the intercepted data position to the broadcast packet.

Parameter d = 0x19: Set the intercepted data starting position 25.

Parameter e = 0x0b: Set the filter data length to 11.

Parameter f = 0x00: Set the filter data position to the scan reply response packet.

Parameter g = 0x04: Set the filter data starting position 4.

Parameter h = 0xff4c000215011223344556: Set the filter data to 0xff4c000215011223344556 (0xff is AD Type).

2.3.2.1 Parameter Description

2.3.2.1.1 Parameter a: type mode

Modes 4 to 16 (a = 0x04 to 0x16) are user-defined scanning device modes based on the sensor used.

Mode 1 (a = 0x01): Bluetooth Temperature Tag (TAH02) mode

AT+MODEL=0104: Start scanning Bluetooth temperature tag (TAH02)mode.

AT+MODEL=0100: Turn off scanning for Bluetooth temperature tags (TAH02)mode.

Mode 2 (a = 0x02): Bluetooth temperature and humidity (ES01) mode

AT+MODEL=0205: Enable Bluetooth temperature and humidity scanning (ES01)mode.

AT+MODEL=0200: Disable Bluetooth temperature and humidity scanning (ES01)mode.

Mode 3 (a = 0x03): Bluetooth ibeacon mode

AT+MODEL=030500190b0004ff4c000215011223344556: Enable the Bluetooth ibeacon beacon scanning mode.

AT+MODEL=0300: Disable the Bluetooth ibeacon beacon scanning mode.

Mode 4 to 16(a = 0x04 to 0x16: user-defined scanning device mode

Note: Different scanning modes can work at the same time.

If the user needs to scan Bluetooth temperature and humidity (ES01) and Bluetooth Temperature Tag (TAH02) at the same time, then just input the following continuously:

AT+MODEL=0104

AT+MODEL=0205

2.3.2.1.2 Parameter b: The effective data length of the interception

b equals 0: indicates that the scanning of the corresponding modes 1 to 16 is canceled.

b is not equal to 0: set the b parameter according to the valid data intercepted by the sensor time.

For example,

in mode 1 (a = 0x01), the default parameter b is 4.

In mode 2 (a = 0x02), the default parameter b is 5.

When it is mode 1 and 2, scanning can be performed after setting the b parameter; the subsequent parameter cdefgh does not need to be set.Mode 1 (a = 0x01): Bluetooth Temperature Tag (TAH02)

In other modes,users need to set the following cdefgh parameters to enable this mode.

2.3.2.1.3 Parameter c: intercepted valid data position

c = 0x00: in the broadcast packet

c = 0x01: in the scan reply packet.

Note: Generally, there are two types of scan data: broadcast packets (31 bytes) and scan response packets (31 bytes).

There is at least one type of broadcast packet. You can use a mobile phone to scan and obtain the complete scan data.

Both the broadcast packet and the scan reply packet are composed of several unit data;

the unit data format is length+AD Type+AD Data.

Therefore, the broadcast packet and the scan reply packet are distinguished according to this rule. The following is a partial AD Type:

For example, the following figure is the complete scan data; related data analysis:

0x020106

length = 0x02

AD Type = 0x01

data = 0x06

1AFF4C0002150112233445566778899AABBCCDDEEFF027177073C31107ADE8F

Length = 0x1A

AD Type = 0xFF (this is a custom data type of the Bluetooth manufacturer)

data =0x4C0002150112233445566778899AABBCCDDEEFF027177073C3

1107ADE8F3D4B88494A0AAF5E20F23155A95

length = 0x02

AD Type = 0x01 (uuid)

data = 0xADE8F3D4B88494A0AAF5E20F23155A95

0C084557383045434343434600

length = 0x02

AD Type = 0x08 (Bluetooth name)

data = 0x4557383045434343434600

2.3.2.1.4 Parameter d: The starting position of the intercepted valid data

The starting position starts from 0.

The broadcast packet and the scan reply packet are two different packets, and the interception should start from 0.

The maximum is no more than 30.

2.3.2.1.5 Parameter e: scan and filter data length

The maximum value is 31.

2.3.2.1.6 Parameter f: Scan filtered data location

f = 0x00: The data location of the scan filter is in the broadcast packet

f = 0x01: The data location of the scan filter is in the scan reply packet

2.3.2.1.7 Parameter g: the starting position of the scanned filtered data

The starting position starts from 0.

The broadcast packet and the scan reply packet are two different packets, and the filtering data should start from 0.

The maximum is no more than 30.

2.3.2.1.8 Parameter h: scan filtered data

It is recommended to use data with UUID and Bluetooth name to filter out unnecessary scan data.

Generally, the more scan filter data there is, the less interference can be filtered.

The data starting from the starting position 0 to the data including UUID or Bluetooth name part can be used as filter data.

2.3.3  ​Decode payload

While using TTN V3 network, you can add the payload format to decode the payload.
