XIAO nRF52840 NFC Antenna Insights

Hi andriandreo,

I have pretty much copied your setup. I am using the a slightly different molex (1462360001). I have then flashed the Seeed Studio nrf52840 with the following code:

#include <NFCT.h>

void setup() {
// set the NFC message as first parameter and the language code as second
NFC.setTXTmessage(“Hello World!”, “en”);
// start the NFC module
NFC.start();
}

void loop() {
}

(I am also using the Seeed nRF52 mbed-enabled Boards Library)

I then used the taginfo app for IOS to try and scan the antenna, but nothing. Are there any other tips you could give me. Am I missing anything?

Also could you give me an estimate of the interregation range of the molex antenna you are using. Is is a couple of cm’s?

Thanks,
Elliott
