Because that was a bug that was fixed in iOS 7.

Any idea why I get back ALL characteristics?
by Rick Mann 06 Aug '13

06 Aug '13

I'm asking only for a subset of characteristics, but -discoverCharacteristics:forService: returns all the characteristics defined in the service. The -discoverServices: call only returns the services I ask for. -- Rick _______________________________________________ Do not post admin requests to the list. They will be ignored.

GATT Service Changed characteristic
by Rick Mann 05 Aug '13

05 Aug '13

A long while back we put in code to notify the GATT Service Changed characteristic every time we connect. We did this because iOS' caching was causing no end of headache for us. Is that now causing issues for me, in terms of connection reliability? Or just enumeration time? -- Rick _______________________________________________ Do not post admin requests to the list.

Getting back more characteristics than I ask for
by Rick Mann 05 Aug '13

05 Aug '13

In trying to better understand what my code is doing, I added a bunch of logging, and now I'm seeing that -didDiscoverCharacteristicsForService is being called for a bunch of extra characteristics that I'm not asking for. I ask for three services (two custom plus 180A, the device service), and as for a total of seven characteristics (2 in the first, 4 in the second, and 1 in the device service). But I get called back for 17 characteristics, and it appears that I'm getting every single characteristic defined in my gatt.xml (for the services I ask for). It's as if I'm passing nil to the -discoverCharacteristics call (but I'm not). I'm using a BLE112. -- Rick _______________________________________________ Do not post admin requests to the list.
