I should make an application with NFC where the entire circuit is powered by energy harvesting.For this reason I thought of using the ST25DV and I have already purchased the X-NUCLEO-NFC07A1 and X-NUCLEO-STM32L476RG.I have successfully obtained the e...
I understand that in order to prevent wireless charging from affecting the ST25 tag, capacitive elements are added inside it. But are there any examples of wireless charging through ST25 combined with Qi?
Hey, I have the ST25DV64KC-DISCO discovery kit, and I want to program it such that whenever an NFC-enabled mobile phone comes in contact, the phone will connect to a Bluetooth address that will be given inside the firmware code. So can somebody pleas...
