This is a purely academic interest, to keep my brain cells exercised.
I'm already familiar with the physical layer, but interested in the deeper layers.

In particular I am interested with the communications protocol. The handshaking, etc.

 

Ok, thanks everyone.

 

I need to make the below board up for running, i ordered 2 boards for Tx and Rx, i don't know much about the LoRa technology, i am trying to follow tutorials and program it using STM32Cube Wio-E5 mini | Seeed Studio Wiki
It will be great if you share any inputs of how to run the program if i can do Tx from one board and Rx in another board?

 

Hello! To end-to-end connections, you only need a simple code in Arduino/PlatformIO or use Zephyr RTOS. I recommend Zephyr RTOS if you are familiar with Real-Time Operative Systems like FreeRTOS, with zephyr you only need to follow the installation Zephyr Getting Started, check the board name: LoRa E5-mini (this: lora_e5_mini) and build the examples with:

1. LoRa send (first board):

• Build:

west build -p -b lora_e5_mini samples/drivers/lora/send

• Flash:

west flash

2. LoRa receive (second board):

• Build:

west build -p -b lora_e5_mini samples/drivers/lora/ receive

• Flash:

west flash

Thank you very much for the information, i have not used Zephyr before, but i will give it a try and update how it goes, surely i will have lot of issues.

I'm sure there's an option with Arduino/PlatformIO, but I don't remember now. If you are stuck with Zephyr, you can ask me.
