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.

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

383

384

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**

385

386

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.

389

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

403

* 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.**

404

405

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