Hi Imam

Is ch201_device defined in a different header file than ch201_gprmt.h?

If so you need to include that header file at the top of ch201_gprmt.h, so that the ch201_device struct is defined at the point where you declare the ch201_gprmt_init function.

For all of this to work make sure you are using include guards, to ensure that you don't define things multiple times (this would cause even more errors).

Best regards
