random channels. Its goal is to enable robust connection between a central wireless data concentrator and a massive amount of wireless end-points spread over a

(((

very wide range of distances.

)))

(((

)))

(((

(((

The PG1302 is design to use with Raspberry Pi to build smart metering fixed networks and Internet of Things applications with up to 5000 nodes per km2 in moderately

(((

PG1302 is fully compatible with RPi3/4, users can use the pre-build OS from Dragino to set up and easy to use the module by Web UI. Or install the raw lorawan driver

149

150

* Flash SD card with Dragino pre-build image which support Web UI.

151

* Install lora packet forwarder in existing RPi OS.

==== 4.3 Access the Linux console ====

(((

(((

Connect the RPI Ethernet port to your router, RPi will obtain an IP address from your router. In the router’s management portal, you should be

)))

(((

able to find what IP address the router has assigned to the RPI. You can use this IP to connect the WEB UI or SSH access of RPI.

)))

(((

Make sure your PC and the RPI is in the same network, then use a SSH tool (such as [[putty>>url:http://www.chiark.greenend.org.uk/~~sgtatham/putty/download.html]]) to access it. Below are screenshots

==== 5.2 Get Gateway ID in Raspberry and input this in TTN v3. ====

335

336

In RPI, run below command to get a Gateway ID

342

343

344

We got the ether (eth0 MAC) address is b8:27:eb:49:62:bc). Add ffff at the end and remove “:” to get the gateway ID: b827ebxxxxbcffff. Input this to TTN v3.

345

===== 5.2.1 Download and install LoRaWAN packet forwarder =====

363

364

Enable SPI and I2C first:

365

366

a)SPI needs to be enabled on the Raspberry Pi

367

368

Run sudo raspi-config to open the config window

[[image:1651745583363-614.png]]

and then run:

409

===== 5.2.2 Config Gateway ID, Frequency Band and Server address =====

410

411

After installation, user can find the configuration file in** /etc/lora/ **Replace the gateway ID we got above to the **gateway_ID** in file **local_conf.json**

412

413

The default LoRaWAN server points to localhost, user need to put the correct server address to the server_address field in file **local_conf.json**, like below.

414

415

(% style="text-align:center" %)

416

[[image:1651745709709-887.png||height="820" width="621"]]

417

418

419

User can find the TTN v3 server address from:

420

421

[[Server Addresses ~| The Things Stack for LoRaWAN (thethingsindustries.com)>>url:https://www.thethingsindustries.com/docs/getting-started/server-addresses/#deployments]]

422

423

424

And the default frequency band is US915 in **global_conf.json** file.

425

426

(% style="text-align:center" %)

427

[[image:1651745838008-820.png||height="650" width="621"]]

428

429

430

* If user want to change to other frequency bands, User can copy the file from **/etc/lora/cfg-302 **and put it into** /etc/lora/global_conf.json.**

431

432

1).Chose your need the name of region frequency.
