Re: HID under GATT on BT 4.0
by Etan Kissling 30 Aug '13

Scott, HID is only partially supported. For example, a mouse won't work, but a keyboard will. Those devices are managed directly by iOS, there's no way for you app to intercept the traffic. iOS 6 does not support HID over GATT. However, iOS 7 may do so (ask in the forums for confirmation because we are not allowed to talk about iOS 7 on this list). Regarding a general profile support: iOS 6 does not support any BT 4.0 profiles natively. For iOS 7 => forums, again. sorry :-) Etan On 30.08.2013, at 21:54, Scott Hamilton <scotth(a)concept2.com> wrote: > I'm trying to find out if a peripheral device can talk to iOS 7 (or 6) "App" using the HID protocol under GATT on Bluetooth Smart (BLE 4.0).

HID under GATT on BT 4.0
by Scott Hamilton 30 Aug '13

30 Aug '13

I'm trying to find out if a peripheral device can talk to iOS 7 (or 6) "App" using the HID protocol under GATT on Bluetooth Smart (BLE 4.0). The device in question is NOT truly a HID device in the strict sense (it's not a keyboard, mouse, etc.) but we have traditionally wrapped our data in HID to utilize built in drivers under Win and OSX. Another question (also asked by Laura Kasso: http://lists.apple.com/archives/bluetooth-dev/2013/Aug/msg00019.html) is this: Is there a list of BT 4.0 standard profiles that iOS supports? EG Heartrate, HID, etc.? Thanks, Scott _______________________________________________ Do not post admin requests to the list. They will be ignored.

Folks - Asking if anybody has an insight into this question: Does BLE scanning by iOS get scaled back with decreasing levels of battery power?

Re: BLE connection to device on iOS 7 only partially succeeds
by Don Clark 26 Aug '13

26 Aug '13

After further investigation and a timely suggestion from CK at Apple, as well as a suggestion from EK here in this forum, I tried my command to the device with my app running on iOS 7 and found that if I changed the write option to CBCharacteristicWriteWithResponse from CBCharacteristicWriteWithoutResponse that the write to the characteristic does in fact occur and complete. Apparently Core Bluetooth on iOS 7 is being more stringent about operations on characteristics and the setting of the properties on those characteristics. I have to review the properties as they are set in the service in the firmware that implements the service. Regarding the "missing services", it also appears that Core Bluetooth on iOS 7 is not exposing the GAP and GATT services in the NSArray holding the discovered services in a CBPeripheral object - the apparent rationale is that these are services the client can do nothing with, and so there is no need to enumerate them. The fact that there were four services enumerated on iOS 6 and only two on iOS 7 is an artifact and of little consequence.
