Mfg data missing in BTLE advertisements in 10.8.3?
by Dave Camp 26 Mar '13

26 Mar '13

I just updated two machines to Mac OS 10.8.3, and I'm noticing that the central's didDiscoverPeripheral: callback no longer delivers the manufacturer data (CBAdvertisementDataManufacturerDataKey) for discovered peripherals. Is this a bug, or is there some new thing I need to do to get access to the manufacturer data again? Thanks, Dave _______________________________________________ Do not post admin requests to the list. They will be ignored.

Re: Minimum connection interval?
by John Earl 26 Mar '13

26 Mar '13

Hi, I'm using an iPhone 4S running iOS 6.1. When starting a connection with my peripheral I see the iPhone starts the connection with a default 30ms connection interval. To try to reduce this interval to 20ms, I tried sending a connection parameter update request from the peripheral following the Apple BT LE guidelines, i.e. 20ms min, 40ms max interval. After this I am seeing a switch to a 37.5ms interval, rather than the 20ms desired. I've tried a few other combinations of connection parameter update values, but have had my requests rejected by the iPhone. Two questions: 1) Does there exist a set of connection parameter update parameters that would yield a connection interval less than 30ms? 2) Does there exist a set of connection parameter update parameters that can restore the 30ms interval after a longer interval has previously been requested and accepted? (e.g. to support switching from a low latency to high latency mode and later back again) Best regards John _______________________________________________ Do not post admin requests to the list.

How to use CBCharacteristicPropertyIndicate?
by Tammo Freese 24 Mar '13

24 Mar '13

Hello, I would like to switch from notifications to indications, to be sure that sent events/data is received on the other side. I tried replacing CBCharacteristicPropertyNotify in the "BTLE Central Peripheral Transfer" with CBCharacteristicPropertyIndicate. That didn't work .The peripheral logged: 2013-03-24 18:50:34.412 BTLE Transfer[15346:907] self.peripheralManager powered on. 2013-03-24 18:50:38.436 BTLE Transfer[15346:907] Central subscribed to characteristic 2013-03-24 18:50:38.440 BTLE Transfer[15346:907] Sent: Here is a bunch of s 2013-03-24 18:50:38.442 BTLE Transfer[15346:907] Sent: ample text.

Does anyone of you know what I did wrong, and how to get indications to work? Take care Tammo Freese _______________________________________________ Do not post admin requests to the list.
