= 2. Configure BH01-LB to connect to LoRaWAN network =

149

150

== 2.1 How it works ==

151

152

153

BH01-LB is configured as (% style="color:#037691" %)**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) ==

157

158

159

Following is an example for how to join the [[TTN v3 LoRaWAN Network>>url:https://console.cloud.thethings.network/]]. Below is the network structure; we use the [[LPS8v2>>url:https://www.dragino.com/products/lora-lorawan-gateway/item/228-lps8v2.html]] as a LoRaWAN gateway in this example.

160

161

The LPS8v2 is already set to connected to [[TTN network >>url:https://console.cloud.thethings.network/]], so what we need to now is configure the TTN server.

162

163

164

(% style="color:blue" %)**Step 1:**(%%) Create a device in TTN with the OTAA keys from BH01-LB.

362

363

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 =====

371

372

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

373

374

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.

379

380

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

381

382

(% style="color:red" %)**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)**

383

384

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

385

386

387

===== 2.3.2.1.3 Parameter c: intercepted valid data position =====

388

389

c = 0x00: in the broadcast packet

390

391

c = 0x01: in the scan reply packet.

392

393

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

394

395

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

396

397

[[image:image-20250213113159-2.png]]

398

399

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

400

401

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

402

403

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

===== 2.3.2.1.8 Parameter h: scan filtered data =====

480

481

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

482

483

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

484

485

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

505

506

507

Check the battery voltage for BH01-LB.

==== 2.3.3.2 Battery Output - BAT pin ====

517

518

519

The BAT pin of BH01-LB is connected to the Battery directly. If users want to use BAT pin to power an external sensor. User need to make sure the external sensor is of low power consumption. Because the BAT pin is always open. If the external sensor is of high power consumption. the battery of SN50v3-LB/LS will run out very soon.
