Learning LoRa ( using RYLR998 ) seeking for guidance
@Umesh Lokhande @techielew @all a few days back, I kick started working with LoRa from @Umesh Lokhande 's YouTube video on LoRa
👇 Here is the link
https://youtu.be/vgYVVC6Lvl8
Key takeaways from video and web are:
Why LoRa, How LoRa works.
How to configure Module using AT command.
Usecase of LoRa.
and more…
After a fair understanding of RYLR998.
I started with RYLR998 LoRa modules
I'm able to configure 2 RYLR998's using USB to UART TTL converter.
Your guidance is appreciated. Queries are asked in next post

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.

Hi, @AJAY KUMAR V I'd suggest setting the same Address for both RYLR998 Lora radio modules. And test if both Lora modules communicate using AT commands (as shown in the video). Please note that the default baud rate is 115200 (factory setting) whereas in my code and testing, I changed it to a 9600 baud rate. So if you're following the instructions from my video then you've to modify your code
Serial.begin(9600);
I hope this will help. Let me know as you progress in your project. Best wishe...3 Replies
What I did till now with LoRa modules:
1. Configured RYLR998 using USB to UART converter.
2. Tried to send count value 0 to 3 digits ex: 500 using Arduino and LoRa(1) to other LoRa(2) module which is directly connected to USB to UART converter received and view values sent by LoRa(1).
I'm not received any data from LoRa(1) at LoRa2). What could be the reason.
Note:
Both LoRa's are in same NETWORKID,
PARAMETERS,
Baud Rate and rest are all same.
But different:
ADDRESS
Q: How can we increase the operating range from a few meters to kilometres?

I tried with 9600 baud as well, 115200 is the default one so I left as it is. Definitely I'll let you know the progress once I restart my hobby project.
And again thank you for valuable information.
