Hi run_ar!

On my device I have encrypted characteristics that trigger the pairing process correctly on iOS and most Android.

I can't pair some Android phones. One is the Nokia 7 plus, with Android 8.1, the same results after update to 9.

The phone connects, but the pairing is not initiated.

Any other method to force the phone to start pairing process on Android

Which can be the reason because some android phones not init the pairing? Only connects to the peripheral, negotiates conn params and nothing more... any clues?

I'm sorry the iOS master control panel source code is not publicly available at the moment.

I see one app from Nordic, itunes.apple.com/.../id1054362403 Pairing perfectly working here while connecting. Do you have git link for this app as like Android (github.com/.../nRF-Master-Control-Panel) Please respond.

The pairing procedure is transparent to the application so it's not possible to actually demonstrate this. But you can look at the HID keyboard example in our SDK to see how to configure attribute properties so pairing is triggered. The only thing you can do from your app is trying to read/write a "protected" attribute.

Hello, Is there any example available github.com/.../ here to give me info about iOS Pairing with nRF51822 ? Please respond.

Ok, Thanks for your time. I will give this detail to nRF51822 developer.

run_ar — Wed, 04 May 2016 12:38:08 GMT

Yes, that's right.

There is two options to get the Pairing dialog.

iOS has to do a read/write of a secure (not open) characteristic.
The nRF51 application can send a SMP request.

OK, so pairing dialog only opens when any secure read/write characteristic used to read/write value in nRF51822 Ble firmware. Its like pairing request from app Right ?

On iOS bonding is handled by coreBluetooth, not the application. According to the guidelines bonding will be initiated if the iOS device receives an att error with "insufficient authentichation". This will only happen if you have configured the attribute table on the nRF51 correctly, e.g. to require security for read/write of a characteristic (in addition the iOS app will have to do a read/write of this characteristic to trigger the error). If your peripheral require encryption you should make sure you configure the attributes accordingly anyway.

Another option to trigger pairing is if the peripheral send a smp request to the iOS device. This will work, but it's not according to apples bluetooth design guidelines.

So at what step, you have issues. You can post the xcode code here.

nRF81522 developer claimed, Already added Secure pairing in it.. But i could not got it.. So i have posted question here to know more about mechanism and how app and nRF communicate with each other,.

RE: Secure connection between nRF51822 and iPhone

Jag Baba — Mon, 02 May 2016 13:51:48 GMT

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

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

RE: Secure connection between nRF51822 and iPhone

Jag Baba — Mon, 02 May 2016 13:49:01 GMT

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

RE: Secure connection between nRF51822 and iPhone

Paul — Mon, 02 May 2016 13:47:03 GMT

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

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).

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.
