I think I need to restructure the design to fix the issues currently has. I'll let you know the update of code sharing after uploading to git

Learning LoRa ( using RYLR998 ) seeking for guidance

Hi @Umesh Lokhande @techielew Happy Deewali. Thank you for all your support. A few days back I finished FreeRTOS based LoRa point to point communication using STM32 Dev board. I dropped the plan of doing LoRa project using Arduino I wanted to get exposure outside of Arduino so I took a step forward and went to the ST dev board. I'm happy to share a few seconds demo. This demo shows when the push button is pressed on the Development board (A) it will send ON command to Development board (B) Thank you again @all

Learning LoRa ( using RYLR998 ) seeking for guidance

Thank you @Umesh Lokhande for your response . 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.

Learning LoRa ( using RYLR998 ) seeking for guidance

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?

Should I use the ESP Framework or Arduino IDE for Commercial Product Development?

Insightful thank you @pallavaggarwal
