STM32CubeIDE 1.19.1 + STM32CubeWL build fails on new project: 'ResponseTimeout' member not found

[R_JPstudent]

Hello,

I'm having trouble building a LoRaWAN project targeting the STM32WLE5JCI6. The same error occurs even on a clean, newly created project, which leads me to believe there might be a compatibility issue between the IDE and the software package.

■ The error I'm facing:

../Middlewares/Third_Party/LoRaWAN/Mac/LoRaMac.c: In function 'ProcessRadioRxDone':
../Middlewares/Third_Party/LoRaWAN/Mac/LoRaMac.c:1650:40: error: 'McpsIndication_t' {aka 'struct sMcpsIndication'} has no member named 'ResponseTimeout'

This error indicates that LoRaMac.c is trying to access the ResponseTimeout member of the McpsIndication_t struct, but the corresponding LoRaMac.h file lacks that definition.

■ My setup:

• Target MCU: STM32WLE5JCI6

• STM32CubeIDE Version: 1.19.1 (Clean install from the official website)

• STM32CubeWL Package: Latest version (Installed via the IDE's package manager)

■ Steps I have already taken:

1. Cleanly reinstalled both STM32CubeIDE and the STM32CubeWL package.

2. Deleted the old project and workspace, then created a new project from scratch in a new workspace.

3. The project was generated with default settings, with only the LoRaWAN stack enabled.

■ My findings:

• The LoRaMac.h file within my new project folder does not contain the definition for the ResponseTimeout member.

• The latest LoRaMac-node repository on GitHub, however, does include this definition.

■ My question:

Is this a known issue with the combination of the latest STM32CubeIDE and STM32CubeWL package? If you know of a solution, your assistance would be greatly appreciated.

I am using an AI to formulate this question.
Thank you.

Hello Ghofrane,

Thank you for your quick response.

I have attached the project file as requested.

Please let me know if you need any other information.

Thank you for your support.

Best regards,

Hello @R_JPstudent 

If you select LoRaWAN Link Layer version 1.0.3, the ResponseTimeout item is not included, and the error occurs. A possible work-around is to comment-out the #if/#endif in the code snippet (at line 1518 in LoRaMacInterfaces.h file). So ResponseTimeout is always included regardless of LoRaWAN Link Layer. If you do this, you will need to re-do it every time CubeMX generates code and over-writes the change. Also, you can change from LoRaWAN Link Layer specification from 1.0.3 to 1.0.4:

PS: This is already reported and will be solved on the future. For more details, have a look at this post.

Best Regards.

Hello @STTwo-32,

Thank you very much for your prompt and helpful response.

Based on your advice, I changed the LoRaWAN Link Layer specification from 1.0.3 to 1.0.4 and was able to successfully complete the build. This resolved the 'McpsIndication_t' has no member named 'ResponseTimeout' error.

After successfully building the firmware, I used STM32CubeProgrammer to write it to the device. I then connected to the device using TeraTerm with the correct baud rate and COM port settings, but unfortunately, no output was displayed on the console.

I suspect the issue is related to the USART configuration, but I'm unsure of the root cause. Do you have any suggestions on what might be causing this issue?
