Hi Alberto,

Thank you for the nice gift

I used this code example and it Work very nice

Sub objEA_ReadData3(DecReceived() As String)
  
    Dim strDec As String
    For a = 0 To DecReceived.Length-1
       strDec = DecReceived(a)
        LogColor("strDec=" & strDec,Colors.Blue)
    Next

End Sub

My question now is when is the DecRecieved array cleared og how can I clear it.

In the start of my com withe my device I expect to see "lppp" and then I get the next data, but when I get my my second data I still have "lppp" in the beging of the dataset

Do you receive the "lppp" in _ReadData3 twice?

I can create the clear method, but I just send to _readdata3 only when coming from external accessory framework...

Hey Alberto,

How are you connecting to you bluetooth device?

Are you using the setup/bluetooth to connect before you open you app?

It would be nice to be able to connect inside the app,

I have made this example a while ago. I don't know if you can use some of it, or maybe add it too your liberary

Hey Mogens,

get the version 1.0.5, I put 1 method ".EAScan" and 1 event _onEAScan

Then EAScan do exactly the same your sample

can you try?

Thanks

Hey Alberto,

The scan thing Works like a charm

But nothing happens with the event _onEAScan

Have I done something wrong?

Sub objEA_onEAScan
    Log("[objEA_onEAScan]")
End Sub

I can se in the debug window that this line : "connectedAccessories:x" changes if connected or not

Look the method:

The event fire only is if ([mgr.connectedAccessoriescount])

If you need to change something, tell me....

-(void)EAScan {
  
  if(_DebugMode) NSLog(@"%s", __FUNCTION__);
  
  mgr = [EAAccessoryManager sharedAccessoryManager];
  
  NSOutputStream *os = session.outputStream;
  
  if(_DebugMode) NSLog(@"connectedAccessories:%lu",(unsigned long)[mgr.connectedAccessories count]);
  
  if ([mgr.connectedAccessories count])
  {
  
  if (os.hasSpaceAvailable)
  {
  if(_DebugMode) NSLog(@"hasSpaceAvailable");
  
  [B4IObjectWrapper raiseEventFromDifferentThread:self :@"_oneascan:" :@[@"Device are already connected"]];
  /*
  UIAlertView *alert = [[UIAlertView alloc]
  initWithTitle: @"Warning !!!"
  message: @"Device are already connected"
  delegate: nil
  cancelButtonTitle:@"OK"
  otherButtonTitles:nil]; [alert show];
  
  [alert show];*/
  }
  else
  {
  [B4IObjectWrapper raiseEventFromDifferentThread:self :@"_oneascan:" :@[@"OK"]];
  /*[self connectBT];*/
  
  
  }
  }
  else
  {
  if(_DebugMode) NSLog(@"showBluetoothAccessoryPickerWithNameFilter");
  [mgr showBluetoothAccessoryPickerWithNameFilter:nil completion:^(NSError *error){ NSLog(@"%@", [error localizedDescription]);}];
  }
  
}
