How to start with nfc on nRF52832 (PCA10040)

[Muhammad Akram Karimi]

Hello everyone, I am looking to start developing something using nfc but I am unable to do so. I am using SDK v12 and it has nfc examples as well like "record_url" or "adafruit tag reader".

These programs compile fine on Keil but don't get uploaded on nrf52DK while ble_app_uart program uploads on nRF52DK just fine.

Can anyone tell me what extra I need to do the following:

• Upload some sample example of NFC on nrf52DK
• Test the example with Mobile Phone with NFC

Thanks

Hi Muhammad.

The ble_app_uart example uses the softdevice, but the record_url example does not. You have to remember to erase the softdevice before trying to flash the record_url example to the board.

When I upload the code to nRF52DK I get an error

""Error: Flash Download failed - "Cortex-M4"

[Muhammad Akram Karimi]

Yes I did erase the flash using Keil

Flash (tab) ==> Erase. Is there any other procedure to erase SD?

[Joakim Jakobsen]

I'm afraid that will not erase the SD from the board. You can use nRFgo Studio to erase the SD.

I have erased the SD and it's working now. Thanks Joakim.
