Linkit-One LoRA Introduction

This section, we will look at the Arduino code for Linkit-It One tracker.

We want the tracker to send data to GIOT MQTT broker through LoRA module and service. Again, the service is not available worldwide. I assume that you have in the service covered area, so the LoRA GIOT MQTT broker can receive my data.

I would assume that you have basic Arduino development skills, if you do not know what I am doing, please study this topic from other resources.

If the GPS tracker data has to be received, then the board has to receive GPS signal correctly. But the GPS has to be delivered to broker through LoRA.

We better make sure it works separately first before we combine both functions code for official release.


So, we will test LoRA module to work correctly first on section 5.2.1.

Then we test GPS code to make sure the board can receive data on section 5.2.2.

Finally, we will put official tracker code on device on section 5.2.3

Let us go test our device now.


Test LoRA device process


5.2.1 Testing with LoRA simple test code

Get a GIoT MQTT account from vendor
Binding module with MQTT broker, note the credentials
Download code from     Search:  "Linkit_One_LoRA_Test, and put it on your device" under howardweng folder

Current download URL:

Taipei LoRA MQTT broker test code, test data with MQTT.fx


5.2.2 Testing with GPS simple code

Download code from

Search:  "linkit_One_GPS_Test"   under howardweng folder
Test Linkit-One GPS test code

Current download URL:


5.2.3 GPS+LoRA Tracker code on device

Download code from

Search  "Linkit_One_LoRA_GPS_Tracker"  under howardweng folder
