how to add nfc function to ble_app_uart?

[leejh]

Hi, everyone.

I have developed own application base on ble_app_uart.

But now I have to upgrade OOB pairing with NFC.

I have some problem.

First, I have to use SDK v11 and nRF52832. (supported nfc min version 11)

and I have refered to ble_app_hrs_pairing_nfc and ble_app_hid_keyboard_pairing_nfc.

So, I added nfc fuction to Originally ble_app_uart application (refer to hrs_pairing_nfc)

(I added both oob and ndef-related functions to make sure there are no problems.)

( SEC_PARAM, OOB_AUTH_KEY, NFC_INIT, NFC_PAIRING_DATA_SET, NFC_LAUNCHAPP_DATA_SET ...and so on.)

(modified Advertising_init refer hrs appliciton.)

I have no error, no warning but led is not working (when nfc field_on).

In addition, only uart messages like the one shown below are sent continously.

(In this picture, I think the nfc field works well.)

Please let me know if there are any things I need to modify or something to watch out for.

Thanks.

In addition, I need only OOB pairing.

First process, NFC tag.

then, BLE adv starting and pairing. when this time, NFC is not work.

Finally when BLE is disconnected, NFC emulate again.

To remove the logging from NFC_HAL, the easiest is to use find-and-replace: find "LOG_HAL_NFC", replace by " //LOG_HAL_NFC".

 

First process, NFC tag.

then, BLE adv starting and pairing. when this time, NFC is not work.

Just for reference, could you check if that works in a newer version of the SDK?

Yes, I have added Uart functionality without error.

After Inserting the uart program, When nfc is tagged, ble starts advertising.

However, if I click the connection in nRF connect APP, it will be disconnected immediately.

Why is it doing this?

Do you check all error codes?

Does your application receives the event BLE_GAP_EVT_CONNECTED when the phone initiates a connection?
