Secure connection between nRF51822 and iPhone

[Jag Baba]

In iOS, I have developed one sample code for BLE scanning and connection with peripheral.

I have one nRF51822 Ble. It has secure pairing mechanism. (Claimed by Hardware programmer.)

when i connect this ble, App never trigger Pair dialog from iOS.

where this iOS code works with Other BLE (Not nRF51822) for pairing..

What was the reason ??

Is there any missing in Hardware firmware or iOS side ?

Here is sample code of iOS

//Creating Central

        NSDictionary *options = @{ CBCentralManagerOptionShowPowerAlertKey : @(NO), CBCentralManagerOptionRestoreIdentifierKey : BLECentralManagerIdentifier };
        
        dispatch_queue_t centralQueue = dispatch_queue_create("com.company.ble", DISPATCH_QUEUE_SERIAL);// or however you want to create your dispatch_queue_t
        self.centralManager = [[BLECentral alloc] initWithDelegate:self queue:centralQueue options:options];
        self.peripheralManager = [[BLEPeripheral alloc] initWithDelegate:self queue:nil];

//Start Scan
    NSDictionary *options = [NSDictionary dictionaryWithObject:[NSNumber numberWithBool:true] forKey:CBCentralManagerScanOptionAllowDuplicatesKey];
    [self.centralManager scanForPeripheralsWithServices:@[ [CBUUID UUIDWithString:SERVICE_UUID] ] options:options];

//Discover and Connect
    [self.centralManager connectPeripheral:self.connectPeripheral options:nil];

At this point my Bluetooth LE hardware 1 pop up Pairing dialog, But nRF51822 not..

Not sure if I totally understood your question.

You will need an App developed for this hardware device. You need to write code for the App to "scan", and find the hardware device, and if this is the device the App is looking for, the App will connect to the device and start communication, or enable the service and start writing, or reading or getting notifications.

But native iOS app/setting will not pop up a "Pairing Dialog" automatically.

I have developed one app. which is perfectly working with one BLE hardware for pairing, reading, writing. But same code not working for pairing only with another BLE chip hardware (nRF51822).

[Paul]

So you are the App developer, not the nRF51822 developer. I need to know what knowledge base you have . LOL

[Jag Baba]

Yes, i m app developer.. If you have any trick about nRF81522, so i will give that info to nRF81522 developer.

[Paul]

Can you see that device UUID, when you are scanning?

[Jag Baba]

Yes, i see.. Also i discover characteristic from it..
