How to use P-NUCLEO-LRWAN2 or NUCLEO-WL55JC1 as gateway and send datas with client not TTN or LORIO.

[AHakk.1]

Hi everyone, I am beginner of stm32. I was using arduino with other lora devices but they consume a lot of power. I was programming lora (ebyte) with HAL_UART. So it was really easy.

Since I want to learn to program stm32 and I need really really low power consumption, I decided to use STM32WL55JC1 or STM32WLE5JC.

I want to communicate 5(or more) end node devices to gateway and gateway will send the datas to api.

So can I use P-NUCLEO-LRWAN2 as gateway and code it with AT command to achieve what I want easily?

If I can't can I use ping-pong example for 5 NUCLEO-WL55JC1 devices as a ping and 1 NUCLEO-WL55JC1 device as a pong ? Pong will be connected the ethernet and it will post ping's datas to my server. Any example code?

Any suggestions and help would be greatly appreciated as I am a beginner. Thank you.

Hi

You can use P-NUCLEO-LRWAN2 as Gateway and program STM32WLE5JC as end nodes.

You can refer Library of STM32Cube_FW_WL_V1.3.0-
