Pairing request when using BLE

seeing this as well

Actually, it's happened if you use two iOS 8 devices. I also want to know how to avoid this.

I don't think so. When using devices with iOS7 or iOS8, I've never found that kind of error alert.

Are you using any of these?:

retrievePeripherals

retrievePeripheralsWithIdentifiers

retrieveConnectedPeripherals

retrieveConnectedPeripheralsWithServices

centralManager:didRetrievePeripherals:

centralManager:didRetrieveConnectedPeripherals

All of them have been removed from ios9 sdk.

Or maybe are you still using ios7/8 sdk? I'm also experiencing many issues with core bluetooth using ios7 sdk in ios9 beta 5.

Fortunately, No. I don`t use anything of them.

I`m still using iOS8 SDK. I`d better try on iOS9 SDK, and share the result. Thanks!

Seeing the same issue here in iOS 9 GM Seed connecting to iOS 8 devices. Have been using iOS 9.0 SDK throughout

Have the same issue on our app - Aroundthen, not a problem before IOS 9.0. Hoping it's fixed in 9.01 but haven't got any 8.0 devices too test against at the moment. Has anyone tried this?

Unfortunately not fixed by 9.01 - still have the same issue with 8.4.1 resulting in pairing request

I encountered the same problem recently.

I had both a CBCentralManager and a CBPeripheralManager on the main queue (nil queue in constructor), and was using the option CBCentralManagerScanOptionAllowDuplicatesKey: @YES. I had a single characteristic with CBAttributePermissionsReadable which shouldn't require pairing.

Moving both managers to their own private serial queues seems to have made the pairing request go away.

_centralManagerQueue = dispatch_queue_create([[NSString stringWithFormat:@"%p: central manager", self] UTF8String], DISPATCH_QUEUE_SERIAL);
_centralManager = [[CBCentralManager alloc] initWithDelegate:self queue:_centralManagerQueue];

Would be fantastic if this does fix the issue. Can you confirm that you haven't had the issue since?
