Hi, I’m trying to do the following action with ACR1255U-J1 in an iOS app:
– Write data to NTAG213
– Stop the reader when the view controller is dismissed
I tried to use the ACS classes:http://www.acs.com.hk/download-driver-unified/7333/ACSBT-EVK-iOS-Mac-0.02.zip, but I had issues with reconnection. So I found your SDK and it’s working better, but now i’m fetching the two issue I told you: write data to NTAG213 and stop the reader when the view controller is dismissed.
To connect to the device I made so:

- (IBAction) buttonCardNFCNumber_TouchUpInside:(id)sender{
    readerManager = [FMSessionManager sharedManager];
    readerManager.delegate = self;
    readerManager = [FMSessionManager sharedManager];
    readerManager.delegate = self;
    readerManager.selectedDeviceType = kFloBlePlus; // For FloBLE Plus
    readerManager.delegate = self;
    [readerManager startReaders];
    
    readerManager.scanPeriod = [NSNumber numberWithInteger:10000]; //in ms
    readerManager.scanSound = [NSNumber numberWithBool:YES]; //play scan sound
    
    // Stop reader scan when the app becomes inactive
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(inactive) name:UIApplicationDidEnterBackgroundNotification object:nil];
    // Start reader scan when the app becomes active
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(active) name:UIApplicationDidBecomeActiveNotification object:nil];
}

Then I set the delegate methods:

- (void)didFindATagUUID:(NSString *)UUID fromDevice:(NSString *)deviceId
- (void)didRespondToAPDUCommand:(NSString *)response fromDevice:(NSString *)deviceId
- (void)didUpdateConnectedDevices:(NSArray *)connectedDevices
- (void)didUpdateConnectedBR500:(NSArray *)peripherals

So when I press the buttonCardNFCNumber it connect to the ACR1255U-J1 and it returns me in method didFindATagUUID the UUID tag of the card. Now I need to stop the reader while the view controller is dismissed so I thought I’ve to use the [readerManager stopReaders] in viewWillDisappear method, but when I pass a card near the reader and the view controller is dismissed it reads the TAG.
Another stuff I’ve to do it’s to write data to the NTAG213, how I can do that? It’s possible? Thank you!
