Can I register a device using NFC on the nRF52840 over a web app on iOS? I am hoping to register the device and cause it to basically wake up after registration.

Hello,

I am curious to see if it is possible to register a device through a web app using the nRF52840's NFC. The goal is to scan the NFC on the device, enter the personal id the user wants to name it, and then a function will turn on the device and go through a testing function. Thank you for your help!

Hi,

The chip can be woken by NFC, so the reader can read a web address where you can enter the ID. From there you might want to consider connecting to the device using BLE to activate the testing function, but you have to turn on the device using NFC using system off mode -> System OFF mode. This will give the following power consumption NFCT active
