May I use slip library code for commercial?

Hi, May I use slip library code for commercial?
I have a project that uses an MCU communicates with an NRF52 BLE module. To upgrade program of BLE module, I flash the bootloader program in SDK example and set a button to switch bootloader and application mode.
I didn't modify any code in bootloader example and must use slip protocol. So I copied slip.h, slip.c, and nrf_error.h these three files to my MCU project.
Again the question, may I use these files for commercial?

BR.

Hi,

Yes you can. You don't have to pay anything to use our SDK, examples, SoftDevices, etc. They are provided for free to anyone using our chips.
