I am not able to run your project. Nonetheless, upon inspection I can see that you are using the same code in the main.c file as you have mentioned in your original post.

However, I am able to allocate floating point variables using malloc and then store values in them and then read and display (see the snapshot below). However, as I mentioned earlier, I was getting issues of printing floating point variables, so I have reverted to using NRF_LOG_FLOAT macro to print floating point on the console.

You can see in the code that the temp is a floating point variables which should contain the values read from the allocated memory for float (that is from the test_data).

Hi,

Thank you for contacting DevZone at NordicSemi.

I think the problem you are experiencing is about the formatting using printing statements.

Can you try printing a floating-point number without using malloc (by direct variable assignment)?

If you fell okay, then pls send me your code (as a project).

Regards,

Naeem
