STM33WL55 Environmental

Hi,

I'm using STM32WL55 Wireless, Long Range Nucleo-64. My goal is to use this floor as an end node. I want to connect my existing sensors to the card via I2C protocol and send the data via LoRa. In the examples I examined, peripherals are used using IKS01A2, but can't I read from the sensor using the I2C pins on the board and send the data via LoRa without using it? I would be very happy if you could help me, good work.

Hello again, You have to collect data using UART. Then, you have to send the data collected to the Gateway. For more details, refer to this playlist.

Hello @Ezgi1 

Yes, you can do this. What you have to do is to start from one of the end node  examples. And then add the I2C configuration and modifie the value to be sent.

    Thank you for your reply,
    Can I take a reading from the analog sensor and send it to the gateway with LORA?

    sure, you can collect any data and send it to Gateway.

    When using dual core, should I make analog reading with M4 and provide LoRa connection with M0? By what method will I ensure inter-core communication? Or assuming that I use the sample code created for stm32wl for a single core, how will I direct the analog reading to LoRa?
    Best Regards.

    To understand more about how this works, I suggest you refer to the LoRaWAN_End_Node_DualCore example on the STM32CubeWL. And for the single core, you can refer to the LoRaWAN_End_Node example.

    Best Regards.

    Hi again,
    I'm running the LoRaWAN_End_Node project. My goal is to capture Uart data with the gateway using STM32WL55 and see it on the server. But I cannot print the uart version. I activated the uart from CubeMX. Is there anything else I should do? How can I print Uart data to the server with LoRa?
