Did you try to add the additional log print as I suggested in my previous reply? Do you see the log messages when you run the app?

If you're developing the app in Segger Embedded Studio (SES), then launching the program in debug mode is really easy. You just build the app and then choose the menu Debug -> Go. It will load the program to target, set a breakpoint at main() function.

If you don't have any idea how to debug a basic C application (single stepping, breakpoints etc) then sorry, I don't have bandwidth to explain it to you. I'm sure there is lots of great material online (tutorials, youtube videos etc) that you can use as reference.

EDIT: see this video by Nordic, titled "SEGGER Embedded Studio - Basics of debugging". Seems like a good stepping stone https://www.youtube.com/watch?v=uP8RYgYGRvI

Have you tried debugging and setting a breakpoint in that function? Then single-stepping to see how it exactly works?

Alternatively, you could try to add some debug prints. E.g. before the if-statement print the value of the led_color variable:

NRF_LOG_INFO("Received value: %d", led_color);

Problem is here:

if (led_color=22)

You are using the assignment operator (=) but you should be using the == operator for comparison. This is elementary C programming stuff. I wonder if the compiler gives you a warning for those lines? Most compilers do (depending of course on what compiler switches are used)
