how to communicate lora with stm32wle5c8?

[sonic]

Hi everyone,

I modified the project https://github.com/STMicroelectronics/STM32CubeWL/tree/main/Projects/NUCLEO-WL55JC/Applications/LoRaWAN/LoRaWAN_End_Node so that my MCU - STM32wle5c8 can communicate with lora but I get the error ("IRQ_CRC_ERROR") as shown below and the MCU can't communicate with lora.

Can someone give me a solution to this problem?

Or is there any way i can check if my MCU can communicate with lora?

Thank you so much my friends

Have you watched the series of videos starting here: https://www.youtube.com/watch?v=vuc6914B0KM ?

(that's part 1; parts 2 & 3 follow on)

Hi,

I watched series of video and combined with the above code example for my MCU and i get the error as shown. here i don't understand what is "IRQ_CRC_ERROR" error. can you tell me what it is and how to fix it?

What code do they use in the videos? Have you tried that code unmodified?

The way I'd start debugging an issue like this is to search the source code for the text  "IRQ_CRC_ERROR" - see what causes that message to be emitted ...
