Dear,

Like I said in the title, I did use the NFC of my PCA10056 with my phone, it works, I also can read some information from nRF52840 by NFC. Right now, I programmed it to light-switch serve node, pca10056 lost the nfc function. Is it right? how can I get the function back?

Thanks,

Dison

Hi Dison, 

Did you add the code to control NFC to the light switch example ? Without any modification in the example, the NFC won't work. 

Which firmware did you flash on the PCA10056 prior to the light switch example ?

Hi Hung Bui,

Thanks for your reply.

Yes, I did not add the code to the light switch example. Since the NFC was working before PCA10056 was programmed, I thought it was a basic support function of the boot loader or nRF52840 system.From your explanation, the new unused PCA10056 is programmed, so would you like to tell me what the code is and where to get it.

Thanks,
