LoRa Module with Arduino- REYAX RYLR998 Tutorial

Learn how to use LoRa Module with Arduino Uno. We’ll use RYLR998 LoRa Module from Reyax Technologies. In this Lora tutorial, we’ll use AT commands to configure radio modules. We’ll communicate two Arduino over wireless LoRa communication protocol. Later, we’ll write arduino code to transmit and receive data.

I have been looking for a good tutorial on this LoRa module for a long time. Finally my project works. Thank you!

[nicoshadjisofokli]

Hello sir and thank you for the great tutorial. I have build this project and works as you described. However could you kindly please help for some improvements needed?

The thing is that I prefer to have an immediate reaction. At your project there is a delay of 1 second from time that button is pressed to the LED lights up and a second delay for the LED to lights off at realising the button. Could that be faster? I reduce the delay(1000); function to lower values but then the project does not work at all.

Another way to make my project works as desired is that the LED at the receiver lights up when turn on the transmitter and LED lights off when turn off the power of the transmitter. In other words LED lights ON and OFF when there is communication or not between receiver and transmitter.

Regards

I am using using 57600 as baud rate to send a simple string message hi. the receiver receives the message only for a few times but not continuous even though the transmitter transmits in a loop. is it because of the baud rate or is there some other reason

[timchapman]

How are you using the RYLR998 without level shifting your serial output to the RYLR998 from the arduino? The RYLR998 is not 5 volt tolerant from what I can find.

are there ay libraries for use in c/c++? I'm programming an ATmega, for my purposes Arduino is not on the menu and I'm struggling a lot making these modules work - although I've configured them with arduino it doesn't seem to be communication between these lora modules and my atmega :( any advice?

[trambinieletrica]

I set up here at home, the receiver receives the signal but does not turn on the led, can you help me?

[jonathanreyesvite]

how you will modify the code to have p2p communication TX-RX in both devices?

Hola, disculpa amigo yo tengo el problema que al conectar al ide de arduino todos los comandos me aparecen +Err=1, alguna sugerencia que me puedas dar porfavor

[gaurav.kharate]

I have dout....
If our lora module work on spi communication...
Like moduoe sx1278then how to connect

[davidpaez]

I have a Flipper Zero but I don't have a second one to test two LoRa modules, so hopefully, this will get me started with simple commands.

Chapter markers would be extremely helpful when going back to reference this video. Thanks.

How long can this module go upto ? I mean what range can it handle

[tonyfremont]

Can Lora gateways "see" these messages? Are they on rotating frequencies from the appropriate band, or are all messages on exactly 865MHz in this example?

[abdulhameedubayathula]

Great one.. You explained the each & every steps clearly

[NikhilKumar-ewmc]

Sir can u plz help me to do the same for different lora module(DTDS-622C), I am having issue working on that.
Sir just plz help me as this is my final year project and my deadline is near...
Plz sir respond me ASAP if u could 🙏

Very interesting product. Makes data transfer easy and safe. Unfortunately it is a closed protocol and there is no chance to integrate into a existing lora network. Communication is only possible between these moduls.

[prashantpitroda]

how much range it can cover? also please guide which frequency band is allowed in India?

[yojithkr]

What's the practical range of communication?

[kewlbeans]

Can Lora RYLR998 Modules be configured WITHOUT using USB-To-TTL module with code below?

Serial.begin(57600);
delay(20);

delay(20);

delay(20);

delay(20);

delay(20);

[jayravan]

For tx side Voltage divider not required?
