PG1302 - DRAGINO

The PG1302 is a multi-channel high performance transmitter/receiver designed to simultaneously receive several LoRa packets using random spreading factors on 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.

36

(((

37

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 interfered environment.

)))

(((

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 in the exist OS.

=== 3. Install the software? ===

117

118

There are two ways to install software in RPi4 to use PG1302.

119

120

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

121

* Install lora packet forwarder in existing RPi OS.

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

145

146

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.

147

148

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

===== 5.5.2 Config Gateway ID, Frequency Band and Server address =====

374

375

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**

376

377

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.

380

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

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

386

* 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.**

395

396

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