USB_TO_LORA_DONGLE

USB to LoRa is a robust and versatile USB to LoRa that allows you to connect without limits. Its excellent range and simple connection allow you to converse with devices up to 5 kilometres distant. LoRa Dongle is the appropriate answer for anybody wishing to develop long-range wireless communication in a number of applications.

How To use

To begin, you must configure the LoRa in transceiver mode by selecting the jumpers shown in the image below:

You can download the XCTU from below :

• Dodnload XCTU

You can use XCTU or Tera Term for Windows to transmit and transfer data, as well as other related software. Among all, XCTU is effective and simple to use. follow the steps below

It receive data from other LoRa Dongle, as you see in below image

Operating Mode

There are four operating modes, which are set by M1 and M0, the details are as follows:

• Normal Mode(M1=0,M0=0)
• WOR Mode(M1=0,M0=1)
• Configuration Mode(M1=1,M0=0)
• Deep sleep Mode(M1=1,M0=1)

Use LoRa USB As Breakout

This device can be used as a breakout, which means you can connect it to any microcontroller or MCU by configuring the UART jumper wires as described below.

Lora GUI For Configuration (run with the help of GUI)

Follow the steps to configure the Lora module:-

Step 1: Setup lora in configuration mode, for this you need to short M0 and open M1 as shown in figure. In case of LoRa Dongle find the mode selection jumper in that board and remove M1 jumper for config mode.

Step 2: Open lora GUI

Step 3: set the COM Port and Baudrate

Step 4: For COM Port go to Device Manager, before this first you need to connect the Lora module via USB cable

Step 5: Write the right COM Port in the GUI,then press connect button

Step 6: Press read button to see the device configuration which lora already have

Step 7: Write the values which you need to configure, for eg: i configure channel and baudrate, after that press write button

Step 8: Restart the GUI, set baudrate and port, then connect and press read button

Step 9: How to Configure Frequency of LoRa Module

Sometimes we are required to modify the working frequency of LoRa module to match regional requirements, so for this follow below steps.

-> Changing frequency using Software for 868MHz & 915MHz LoRa module:

Frequency = 850.125MHz + CH*1MHz

0-83 total of 84 Channel available

So, when 5 selected Frequency = 850.125MHz + 5*1MHz Frequency = 855.125MHz

-> Changing Frequency using Software for 433MHz LoRa Module

Frequency = 410.125MHz + CH*1MHz

0-83 total of 84 Channel available

So, when 5 selected Frequency = 410.125MHz + 5*1MHz Frequency = 415.125MHz
