Hi,

It is not entirely clear to me what you are asking about. However, if execution does not stop in the breakpoint inside if statement, then the condition of the if statement is not hit. So for if(app_fifo_put(&m_nfc_tx_fifo,msg_chunk) == NRF_SUCCESS) that means that the return value was something other than NRF_SUCCESS. Looking at the return value should give some insight into what went wrong.

thank you.

recently,i have attempted to use nfc_uart example in NRF5_SDK_15.0.0_a53641a on PCA10040,but i found:

uart can receive data from computer,but when i put a breakpoint in

if(app_fifo_put(&m_nfc_tx_fifo,msg_chunk) == NRF_SUCCESS),

it cannot stop,it means NFC cannot send data from uart,i donot know the reason.

in addition,uart can receive data from NFC and display on the computer.

i need your help,thank you very much!

best regards.

The state transition from IDLE to READY_A happens when there is a ALL_REQ from the NFC reader (see state diagram). This is allready there in the NFC HW peripheral and is not something you have to (or can) implement.

thank you very much!

i still want to know the implementation of translation from IDLE to READY_A,can you tell me simply?

thanks again!

There are a number of NFC apps for Android. NFC Tools seems to be one of the more popular.

thank you very much!

according your suggestion,i have added LIB to my project.

Hi,

Making your own NFC implementation will be very time consuming, so I strongly recommend that you use the library we provide in the SDK. I recommend you start looking at the NFC examples in the SDK.

Regarding the errors you get this is undefined symbols. The typical reason for this is either that you have not included the .c file where it is implemented, or that you have not enabled the relevant module in your projects sdk_config.h, so that it is removed by the preprocessor. You also have a few warnings for unused variables, which can be fixed by removing the variable declarations.
