The host OEM user manual must also contain clear instructions on how end users canfind and/or access the module and the FCC ID: ZHZPG1302
FCC Statement:
"This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the
following measures:
—Reorient or relocate the receiving antenna.
—Increase the separation between the equipment and receiver.
—Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.—Consult the dealer or an experienced

1Introduction
1.1 What is PG1301 LoRaWAN Concentrator?
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.
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.
1.2 Features
✓ Support Raspberry Pi 3B/3B+/4
✓ Up to -142.5dBm sensitivity with SX1257 Tx/Rx front-end (see reference design)
✓ 70 dB CW interferer rejection at 1 MHz offset
✓ Able to operate with negative SNR, CCR up to 9Db
✓ Emulates 49x LoRa demodulators and 1x (G)FSK demodulator
✓ Dual digital TX&RX radio front-end interfaces
✓ 10 programmable parallel demodulation paths
✓ Dynamic data-rate (DDR) adaptation
1.3 General Interfaces
✓ SPI interface for LoRa
✓ Specifications:
✓ Power Input: 5v, 1A
✓ 1 x SMA antenna for LoRa

2Example: Set up as LoRaWAN gateway.
2.1 System structure
This example is an example to show how to set up the PG1301 + RPi as a LoRaWAN gateway
to use with TheThingsNetwork(TTN) LoRaWAN server.. Set up method for other server are
similar

PG1302 LoRaWAN Concentrator 8 / 20
2.2 Hardware Installation
Important Notice: Please power the RPI with 5V,2A cable.
RPI in this example is RPI model 3B with fresh Raspbian OS install.
pi@raspberrypi:~$ cat /etc/os-release
PRETTY_NAME="Raspbian GNU/Linux 8 (jessie)"
NAME="Raspbian GNU/Linux"
VERSION_ID="8"
VERSION="8 (jessie)"
ID=raspbian
ID_LIKE=debian
HOME_URL=http://www.raspbian.org/
SUPPORT_URL=http://www.raspbian.org/RaspbianForums
BUG_REPORT_URL=http://www.raspbian.org/RaspbianBugs
2.3 Install the software
2.3.1 Get Gateway ID in Raspberry and input this in TTN.
In RPI, run below command to generate a Gateway ID
ifconfig eth0 | grep eth0 | awk '{gsub(/:/,"");print $5"ffff"}'
Here we got b827xxxxx65fffff. Input this to TTN. Make sure to select legacy packet
forwarder

www.dragino.com
PG1302 LoRaWAN Concentrator 9 / 20
After set up, the status should show not connected as below:
2.3.2 Download and install LoRaWAN packet forwarder
In RPI , run:
wget http://www.dragino.com/downloads/downloads/LoRa_Gateway/PG1301/software/lorapktfwd.dep
This will download the packet forwarder package from Dragino Server to RPI.
run “sudo dpkg -i lorapktfwd.dep” to install pkt fwd, pktfwd will auto run after this
command. But the TTN will still show not connected because the Gateway ID doesn’t
match.

PG1302 LoRaWAN Concentrator 10 / 20
2.3.3 Config Gateway ID, Frequency Band and Server address
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
The default frequency band is EU868 in global_conf.json file and the default LoRaWAN
server points to TTN.
➢ If user want to change to other frequency bands, User can copy the file from
/etc/lora/cfg and rename it to global_conf.json and put it into /etc/lora .
➢ If user wants to change to other LoRaWAN server, modify the global_conf.json file.
➢ To enable/disable GPS module, modify file /etc/lora/local_conf.json
2.3.4 Check result
Run below command to restart the pkt_fwd:
sudo systemctl stop lorapktfwd
sudo systemctl start lorapktfwd
The pktfwd will start with the new gateway ID and TTN should show the connection ok:
If there are LoRaWAN nodes transmits nearby, we can see the traffic in TTN –> Gateway -
-> Traffic
