Connect HT-M02 to a LoRa Server
Summary
This article aims to describe how to connect HT-M02 Gateway to a LoRa server, such as TTN, ChirpStack, which facilitates secondary development and rapid deployment of LoRa devices.
Before all operation, make sure the HT-M02 is runing well . If not, please refer to this HT-M02(4G/LTE) Quick Start document.
Connect to TTN
Register a LoRa gateway in TTN
Create and active an account in TTN. Select Gateway
in the console page.
Fill in the HT-M02 information as shown below and complete the addition.
Gateway EUI – The unique ID of HT-M02 gateway;
I’m using the legacy packet forwarder – Must select this;
Frequency Plan – Must matach the LoRa band configuration in HT-M02;
Router – Must use the default router allocated by TTN system.
Tip
That four points are the key to success connection with TTN.
Connect to TTN
In the HT-M02 gateway, only the server address and port need to be configured.
config the server address
and port
in global_conf.json
:
sudo nano lora/packet_forwarder/lora_pkt_fwd/global_conf.json
At the end of this file, make suitable changes:
"server_address": "router.cn.thethings.network", /*The server IP address or domain*/
"serv_port_up": 1700,
"serv_port_down": 1700,
ctrl + O
to save and ctrl + X
to exit, and restart the service:
sudo systemctl restart lrgateway
Check whether the system running normally:
sudo systemctl status lrgateway
The TTN’s router addresses for different region:

View gateway status, it is runing::
Connect to ChirpStack server
ChirpStack is the most popular LoRa server open source project, widely used in many fields, and also the best choise for a private LoRa server.
ChirpStack Installation guide: https://www.chirpstack.io/overview/

ChirpStack Gateway Bridge
One thing need attention! the ChirpStack need a special service named Gateway Bridge
, which converts LoRa® Packet Forwarder protocols into a ChirpStack Network Server common data-format(JSON and Protobuf).
the Gateway Bridge
service can running on the Raspberry Pi or the ChirpStack server.
Install ChirpStack Gateway Bridge: https://www.chirpstack.io/gateway-bridge/install/debian/
Register LoRa Gateway in ChirpStack
Fill in the HT-M02 information as shown below and complete the addition.
Gateway ID – The unique ID of the HT-M02 gateway.
Connect to ChirpStack server
