I got bluetoothmanager working to find my bluetooth devices.
But I cannot connect my earphone. This should be connected by the PIN code 0000

I tried setting the pincode before the connect, after the connect. It just wont work.

Does anyone has any experience with pairing devices with BluetoothManager?
I can turn bluetooth on and off and scan for devices, which will also come up in my list, but I can't figure out how to set the PIN code for pairing the devices..

There are functions about
Code: 
In bluetoothDevice:
- (void)setPIN:(id)fp8;

In Bluetoothmanager:
- (void)setPincode:(id)fp8 forDevice:(id)fp12;

But setting them before or after connect are no option
for example:
Code: 
- (IBAction)connect:(id)sender {
    BTListDevItem *item = (BTListDevItem *)[btDevItems objectAtIndex: 0];
    [logs setText: [NSString stringWithFormat: @"deviceConnect to %@", item.name]];

NSLog(@"Connecting to: %@", item);

    [item.btdev setPIN: @"0000"];
    [item.btdev connect];
}

or

- (IBAction)connect:(id)sender {
    BTListDevItem *item = (BTListDevItem *)[btDevItems objectAtIndex: 0];
    [logs setText: [NSString stringWithFormat: @"deviceConnect to %@", item.name]];
    NSLog(@"Connecting to: %@", item);

    [btManager setPincode: @"0000" forDevice: item.btdev];
    [item.btdev connect];
    
}

Here I'm forcing to connect to the first device in the list, just for testing because I only having bluetooth earphones at the moment. But it wont work.

I got some error logs about this problem when using this:
Code: 
- (IBAction)connect:(id)sender {
    BTListDevItem *item = (BTListDevItem *)[btDevItems objectAtIndex: 0];
    NSLog(@"Connecting to: %@", item);

    [item.btdev setPIN: @"0000"];
    [item.btdev connect];

//Or this
//    [btManager setPincode: @"0000" forDevice: item];   
//    [btManager connectDevice: item];
}

I don't know if this will help with your problem or not, but here's some Ray Wenderlich tutorials. They have a ton of them and they are very good.

Hi KarlJay,

Indeed I also been through these tutorials a while ago ;-)
But unfortunally, I really need to pair with the device, and whatever I tried... It did not like to pair with my headset or wireless keyboard.

Hi Dennis, I have the same problem that you had. Did you find a solution?

Thanks

Hi Patrakas,

Unfortunally I could not found a solution for this issue.
I'm not sure if it's even possible to pair 'all' devices with the BluetoothManager.
Here and there I read that you can only pair certain services with the BluetoothManager... So I did not agree, and found a lot of info which actually told me it should work ;) But ... in the end I gave up, and scrapped this 'part' of my testing application.

If you do find a solution, please update my post :)

I think there was a post years ago about Apple not allowing BT connection to just any device.

I don't know BT, so I can't say, but does it give you an error code or is there some standard as to what can and can't be connected to?

I know Apple has been know for being very strict about what they allow to connect to their sandboxed system. I can imagine that they would have strict rules about BT. Esp now that the new BT standard is supposed to be MUCH faster, it can be used for stealing files (music, movies, etc) and Apple has always tried to stop that.
