I see you have created a new question for that, so we will continue in that thread.

Thank you for the response.

I am encountering lot of errors while merging the nus and fds example.

How to i efficiently merge the 2 projects along with all the includes?

Hi,

That all depends on how you want to do it. You will get a string with the characters written by the central (phone), which is handled by the nus_data_handler() function in the NUS example. There you can do whatever you like with it, in addition to or instead of logging it, as is done in the current example. If you would like to copy it to another string, then you can do that (for instance using strcpy() or memcpy()), and if you like, you can write it to flash using, for instance, FDS or another method. This is up to you.

in the NUS example when i use the RX Characteristic to send data i am able to view the data on the terminal application. I want to copy and store this data in a separate string, how do i do that?

sorry if these questions seem too basic, I have only recently started working on MCUs.

Hi,

The NUS example seems like a sensible starting point. It supports transferring data in both directions out of the box. Regarding flash storage that depends on how you want to do it, but if you want to use FDS, then you can refer to the FDS example.
