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.
