License issues.

[Al Bundy]

I would like to use nRF51422 in commercial product and I use your SDK. There are 2 files: app_uart.h and app_uart_fifo.c that I would like to modify a bit. I would like to make sure that I understand your policy. I can copy them and modify provided that I keep your headings in both files, right ? Am I free to add my own headings below yours?

Hi Albundy,

You are free to modify any source code in the SDK as mentioned in the license text here:

(b) to modify any source code contained in the SDK solely as necessary to implement products developed by Licensee that incorporate an nRF IC ("Licensee Product").

One note is with the Bluetooth profile libraries, if you modify the files, you would need to re-qualify the profile on your own. You will find this text in those libraries:

/* Attention!

• To maintain compliance with Nordic Semiconductor ASA’s Bluetooth profile
• qualification listings, this section of source code must not be modified. */

So I can even delete your headings ?

@Albundy: No, the header should be kept. In most files you can find this :

 *   1. Redistributions of source code must retain the above copyright notice, this
 *   list of conditions and the following disclaimer.

or this:

 * Licensees are granted free, non-transferable use of the information. NO
 * WARRANTY of ANY KIND is provided. This heading must NOT be removed from
 * the file.
