The NFC example (launch app) on SDK12 does work on my device. However, when I copy exactly the same code into my own project, the NFC does not work. The difference is that I have S132 soft device flashed, but that does not explain the problem, because I was able to add soft device into the SDK example, and it continued working.
My question is: what are the critical things for NFC to work? For example, do I need to set some specific flags into sdk_config.h? In an earlier question here, concerning SDK11, there was a conclusion that CLOCK_ENABLED must be set for NFC to work. But this is already set on my project, so maybe there is some other hidden thing missing? Wrong clock frequency somewhere? I/O configuration flags? Any ideas what I could try?
