How to use LoRa with Arduino | LoRa Tutorial with Circuit Code and AT commands | Reyax RYLR896

In this video, I have shown how to use Lora with Arduino for different IoT projects. Here we will use the Reyax RYLR896 Lora module to design a Lora Arduino circuit that can control a relay module from 10 KM distance.

Purchase link for the RYLR896 LoRa Module:

Before getting started with the LoRa module I suggest you to watch the complete video on Lora basic tutorial but you can skip any portion of the Lora tutorial video by clicking on the following timestamp.
00:04 What is LoRa and Lora features
01:19 How to set LoRa Bandwidth, Address with AT commands
04:30 How to connect Lora with Arduino
06:01 Lora Transceiver connection on Breadboard
07:00 How to connect Relay module with Arduino Lora circuit
07:56 simple LoRa Arduino code to turn on and off a light bulb
10:50 License free Band for LoRa module

Download the Arduino Code and Datasheet of the Lora Module from

During the video, we will discuss the different features of the Lora module and how we can send signal with the Lora device without using any WiFi or Bluetooth signal. Here we will use simple AT commands to send the signal from the transmitter circuit to the receiver circuit. This Lora Transceiver circuit is the best option for different IoT applications in rural areas. As the Lora range can be even more than 10Km so we can use this Lora circuit in agricultural land for controlling the water system, monitor moisture temperature, etc.

After watching the video you can easily design the Lora Arduino circuit for your upcoming IoT projects or home automation projects.

⚠ This video took a long time to make if you would like to buy me a coffee to say thanks, link below: ☕

[MrNams]

Can we broadcast message from one lora node to all other lora nodes without gateway?

[marios_ideas]

uick uestion. in this video you set up a sender and receiver. If I want to do both way communciation how can I resolve the 3, 3V dillema. Is it at all possible to set it up with Arduino Nano or Uno. Or should I switch to Arduino Pro mini that works on 3, 3V logic.

[PoyoyoChannel]

I have a question is there possible to transmit a signal to reciever the components of transmitter including fire alarm with sprinkler

[marios_ideas]

You did not connect RST pin. Should it be connected and if so to which microcontroller pin

[RobertoLeiteBR]

Thanks for sharing. The LORA library for Arduino failed for me, but you proved that it was not even needed. My modules are working now. Cheers from Germany. (+5, 13 USD - enjoy your coffee)

[danishalireza]

Great Video indeed. But what to do if we want to switch it faster? There is a delay between transmitter input and receiver output. Thank you

[hsuan-tingou]

I'm just wondering the transmitter and the receiver are the same module?
And also what is the largest distance can be between the transmitter and the receiver

[Popart-xhfd]

Hi, very nice set up. I have a question though, how you make sure other devices don't trigger that same led? I ask this because there is no address set for the devices on you code to filter out other external devices messages.

Thank you for explaining the AT commands. I am just getting started and did not realize that. You make excellent videos that help so many, you are kind to share your knowledge.

[MrMaximal]

porque el tiempo de respuesta es tan lento en el minuto 6:31 se aprecia cuando pulsa el botón y tiene un retardo es un diseño en el código

[jntkumar]

How far it's range? Have u tested it's range without modification in antenna and hardware part ?

[surflaweb]

Bro this lora module can save the band in its memory, I have a lora RYLR998 and every time that I turn off it the band is reset to 915mhz. This modules that you used can saves the band in its memory?

[Charles-ltrr]

Thanks very much my dear for this nice video. Please, assuming I am having 4 receivers, how can I add a keypad on the transmitter side so that I will use the keypad to write the destination address of the receiver that I will like to communicate. The lcd or OLED display in transmitter side will be used to display the receivers destination address when I am typing them. Thanks very much for your understanding and concern. Please, I am waiting for your reply

[jacobconradcamilon]

thank your video is great but im thingking if it is possible to have multiple Transmitter with only one receiver. Do you have example for that

[joebro]

When I set my Frequency Band, I receive the +OK, am able to confirm the change, however after removing power and powering back on, the band reverts back to the previous band. Any ideas? I was able to set 2 modules last week and am unable to change them now.

[Renato]

Thank you for the video. Can this Tx circuit connect to a Lora gateway as a way to control and watch sensor data in a IoT platform? How long would the battery last with this LED cricuits Rx and Tx?

[joescopo]

Great video! Very interesting and informative. What would I change in the code in order to get the LED to turn on while pressing the button only and turn off when not pressing the button? Again, thank you for the great videos.

[aps]

Can we use 2 or more lora transmitter with 1 lora transmitter?

[hakobyantelman]

Hi. Thanks for this video. Is it possible to control with one transmitter few receivers? Led1 will turn on led on 1st receiver, led2 will turn on led on 2nd receiver and e.t.c.
