We are using an NFC tag that complies with ISO14443A and B standards (ISO-DEP) and supports ISO/IEC 7816 security. We are attempting to write some data using CoreNFC's NFCNDEFReaderSessionDelegate. We can detect the tag, but when we try to connect to it, it displays NFC Error (Tag Connection Lost). We also attempted NFCTagReaderSessionDelegate, but we were unable to detect the tag at that moment. Note that we have included the Privacy - NFC Reader Usage Description and ISO7816 application IDs for NFC Tag Reader Session to info.plist. Tag Reader Session Formats for Near Field Communication in entitlements.plist Can you advise on whether the problem is caused by the tag we're using? Or the CoreNFC library does not support writing? Thank you for your valuable time and assistance

I'm trying to determine the connected devices via Bluetooth in iOS application using Core Bluetooth library and unable to get a list of the devices which are in connected state.  I've tried using "retrieveConnectedPeripheralsWithServices" function to get the connected devices but this requires a specific service to search for. I'd like to get a list of all connected Bluetooth devices, not just specific-service Bluetooth devices. In order to get all the services, I therefore pass an empty array of services to this function, however, the function does return an empty list. Is it possible to get a list of Bluetooth devices connected on iOS using Core Bluetooth? if not, please suggest an alternate option to achieve this in iOS. Thank you for your time and assistance.
