Invalid Input: Must be project's active .ioc file.

[SSWM]

Hi,

I am new to the STM32 platform. As for research purpose I got myself the B-L462E-CELL1 board. I need to connect to the internet and send sensor data to AWS IoT Core. 

I tried to explore the STM32CubeExpansion_CELLULAR package to change the code according to my need. In that process I am lost. Can anyone guide me on which file should I focus on changing the code? This is too much to code to start with. I have already checked the cellular wiki but it wasn't very helpful to me. 

I wanted to change the .ioc file and configure the pins for my sensor but i can not open it (SS attached). Any suggestions on how to fix it? I have tried renaming the Prj_B_L462E_CELL01.ioc file to 'STM32CubeExpansion_CELLULAR_V6.0.0.ioc' but that also shows the same error. 

Thanks and Regards,
SSWM

Hello @SSWM, 

The error message indicates that the STM32CubeExpansion_CELLULAR_V6.0.0.ioc file is set as the active .ioc file for the project, but you are trying to open Prj_B-L462E-CELL01.ioc

In STM32CubeIDE, right-click on the Prj_B-L462E-CELL01.ioc file in the Project Explorer and select "Set as Active .ioc File".

Hi @Sarra.S,

I followed your instructions but I couldn't find the "Set as Active .ioc File". option.

Hi @Sarra.S,

The thread wasn't that helpful. I still couldn't figure out how to set the .ioc file as active. However, I could open it with the option open from an existing .ioc file.
