[lorawan node application] the application and power consumption of Anxin ra-08/ra-08h module in lorawan network

Preface

This article mainly introduces how to configure Ra-08H module / Development board access LoRaWAN Relevant contents of the service .LoRaWAN The difference in LoRa Technology lies in ,LoRa The signal transmission goes through the physical layer , and LoRaWAN Is the media control layer protocol , Mainly used for network layer protocol .LoRaWAN The main components of the architecture are ：LoRaWAN gateway 、LoRaWAN node 、LoRaWAN Network services and LoRaWAN The application service consists of four parts . The server to be connected this time is the server integrating network services and application layer services , The gateway uses .

2 The server controls the platform operation

2.1 Configure the gateway docking content

Configure the gateway frequency band , Select frequency band , Configure the center frequency of the receiving window , Maximum and minimum transmission frequencies , bandwidth , Spread spectrum factor and other related parameters .

2.2 Configure network service related parameters

Configure the data rate of the receive window 、 Receiving window 2 Frequency size of 、 Transmit power, adaptive rate and other related parameters .

2.3 Create nodes

2.3.1 Create an application

Create a new application , Set the name of the app , Select the application key type , Save application .

Configure application secret key , Can generate random numbers , Other content uses the default configuration , Click save and apply .

2.3.2 Create a node

Click to enter the created application , input device EUI（ Customizable ）, Click on “ add to ”

Set the relevant parameters of the node , Include ： Equipment name 、 How nodes work （Class A/Class B/Class C）、 Network access mode （ABP（Activation By Personalization）/OTAA（Over The Air Activation））, Other configurations default to , Click save and apply .
OTAA The network access mode configuration interface is as follows ：

Set up ABP Network access mode , Fill in the equipment address 、 Set the random number with the session secret key 、 Set random number for network session key , Other configurations remain default , Here's the picture ：
