NFC "Wake on nfc" example not working.

[erosembedded]

I have a Rigado BMD350 dev board. This has the NFC tag antenna included.

I am just trying to get the example code to work on any of the NFC examples. I can't seem to get any of them to work with my phone.

Info:
Segger embedded studio
Phone: Samsung Galaxy S9
SDK V15.2
Example : wake_on_nfc_pca10040

I have NFC turned on on my phone. I have not modified the example code in any way. 

Steps I take:
1) Erase All with nRF Studio
2) Debug build with segger embedded studio (No errors or warnings)
3) Click "build and run"
4) Demo start and LED1 is on and LED2 blinks
5) Hit Button 0
6) LED1 turns off and LED2 stop blinking
7) Unlock phone
8) Place phone over NFC antenna. (Came with the BMD350)
9) Nothing happens.

There must be something simple I am missing. All the other forum post are for getting it to work with a softdevice or with their custom apps.

The Rigado BMD350 does probably not have a 32 kHz crystal. The examples in  the SDK are mostly setup to use a external 32 kHz crystal since this is present on the DK. You must set the 32 kHz clock to use the RC oscillator instead. 

See this post: https://devzone.nordicsemi.com/f/nordic-q-a/13310/in-nrf52832-how-to-use-the-internal-rc-oscillator

The BMD350 does have an external crystal. All other Nordic SDK examples work, just not the NFC ones.

I usually like to use nrfjprog to erase the module:

nrfjprog -f nrf52 --recover

... then load the new firmware. This ensures the old S132 is fully erased.

Ensure the NFC antenna is connected properly. The Rigado logo should be visible (up).
