Prior to iOS10, writing data to a peripheral with: peripheral.writeValue(data, forCharacteristic: characteristic, type: .WithoutResponse) would not call the delegates didWriteValueForCharacteristic (as per documentation). However, the same code in iOS10, the delegate receives a call to didWriteValueForCharacteristic regardless of the rite type The error is nil and the char is the one we just wrote to (using .WithoutResponse). iOS 10.0.1, iPhone 6s+, Xcode8, iOS10 sdk, iOS 10 deployment target radar://27269173 _______________________________________________ Do not post admin requests to the list.

Re: iOS 10 Beta - Bluetooth Stops Advertising When Screen is Locked

Hi, We are having the same issue here. On iOS 10, the iPhone stops advertising a few minutes after the screen is locked (and starts again if the screen is unlocked, without opening the application). This is working fine on iOS 9. Does anybody have any update about it? Is this a bug or the BLE background behavior changed on iOS 10?

Re: Bluetooth sniffer

Hi Gordon In many cases, you can try to log the Bluetooth at the HCI level either on your device or on the remote. For Android, with some versions at least, you can capture the HCI log in the BTsnoop format which can be opened in Wireshark.
