BASIC DA1468x DSPS DA14681

Hi i have wrote my firmware on sdk 1.0.14.1081 and i m using DA14681.

I want to use Serial port service in my project which is based on SDk 1.0.14.

文档“嗯- b - 084 - _da1468x_serial_port_service_reference_application_v1.1" says in page # 10 that "The SPS reference application is developed based on DA1468x SDK 1.0.12 with minor modifications."

So i have 2 questions?
1 - Will this SPS will work for SDK 1.0.14?

2 - What is the meaning of patched sdk files? ( The patched SDK files are: hw_uart.h, ad_uart.h, ad_uart.c, sps.h and sps.c.
)
