Hi,

I am using a POS device for card swipe. its working good. i have used following codes.

• (id) init { self = [super init]; if (self != nil) { NSNotificationCenter *notificationCenter = [NSNotificationCenter defaultCenter]; EAAccessoryManager *accessoryMamaner = [EAAccessoryManager sharedAccessoryManager];

[accessoryMamaner registerForLocalNotifications]; [notificationCenter addObserver: self selector: @selector (accessoryDidConnect:) name: EAAccessoryDidConnectNotification object: nil]; [notificationCenter addObserver: self selector: @selector (accessoryDidDisconnect:) name: EAAccessoryDidDisconnectNotification object: nil];

NSArray *accessories = [accessoryMamaner connectedAccessories]; accessory = nil;

session = nil;

for (EAAccessory *obj in accessories) { if ([[obj protocolStrings] containsObject:@"com.XXXXX"] || [[obj protocolStrings] containsObject:@"com.YYYYYY"] ) { accessory = obj; break; } }

if (accessory) { session = [[EASession alloc] initWithAccessory:accessory forProtocol:@"com.dailysystems.DS247"]; if (!session) session = [[EASession alloc] initWithAccessory:accessory forProtocol:@"com.usaepay.ipos"];

if (session) { self.deviceConnected = YES; [[session inputStream] setDelegate:self]; [[session inputStream] scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode]; [[session inputStream] open];

[[session outputStream] setDelegate:self]; [[session outputStream] scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode]; [[session outputStream] open]; } else { UIAlertView *accessoryInfo = [[UIAlertView alloc] initWithTitle:@"Alert!" message:@"Hardware is not connected." delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil]; [accessoryInfo show]; [accessoryInfo release]; } } } return self; } When i disconnect the accessory it gives me accessoryDidDisconnect and when i connect it gives me accessoryDidConnect, But Problem is after that accessory stop working it does not respond to command. i tried to release the alloc and alloc again but no use. Please tell me if some one have any idea how to get the accessory work again. Thanks in advance.
