Hi everyone,
I want to develop a end node module using STM32WL55JC. I have tried to LoRaWAN_End_Node_DualCore example project and the end node has connected to TTN. After that the usart1 enabled and try to send message but i couldnt send message. How can i use peripheral(i2c, uart, adc etc.) with LoRaWAN_End_Node_DualCore/LoRaWAN_End_Node.

Hello @turen and welcome to the ST Community :smiling_face_with_smiling_eyes:.
I suggest you follow this playlist specially the implementation of the IKS01A3 (video 6) that use I2C to communicate with the example. you can try the same steps and take a look at the changes that acquired on the .c/.h files. Then, you can adapt this method to your specific needs.
Best Regards.

The LORAWAN middleware need to be activated on both contexts "Cortex-M4 and Cortex-M0+" for Dual core projects.

I dont want to use IKS01A3 library because Software package not contain all sensors. I want to learn how to use stm32 Peripherals with lorawan end node app and then i will create custom library.

Hi,
You don't have to use the IKS01A3. You just have to refer to the video to understand how to use an API (I2C as example) with a LoRawan end node project.
Best Regards.
