This article explains how to configure Ai-thinker Ra-08H module for LoRaWAN services and connect a node to it.

LoRaWAN is a wireless network protocol that links the LoRa signal (sensor data) to the application(s).

LoRa is the radio signal that carries the data, on the other hand LoRaWAN is the network communication protocol that controls and defines how that data is communicated across the network(including both nodes and gateway).

The main components of LoRaWAN infrastructure are LoRaWAN gateway, LoRaWAN node, LoRaWAN network service, and LoRaWAN application service.

1.3.1 How to Program Ra-08H module

According to above connection, unplug the RST pin wiring on the module.

Use below given software to program the module.

Open the firmware program, choose the firmware file, and click “Erase All” to erase the module’s original firmware. Once erase is done, click “Start” to program new firmware.

1. 3.2 RA-08H-KIT development board program operation

Connect the RA-08H-KIT development board with PC using USB cable, keep the IO2 button press, short press the RST button.

Open the firmware program, choose the firmware file, and click “Erase All” to erase the module’s original firmware. Once erase is done, click “Start” to program new firmware.

2. Server control platform

2.1 How to configure the gateway

Configure the gateway frequency band, select the frequency band, and configure the center frequency of the receiving window, maximum and minimum sending frequency, bandwidth, spreading factor and other related parameters.

Set the related parameters of the node, including: the work name and node working method (Class A/Class B/Class C), and the network access method（ABP（Activation By Personalization）/OTAA（Over The Air Activation））, other configure as default, click save and apply.

OTAA network access method configuration interface is as follows:
