More info: If I manage to connect in the simulator, then I get back all the characteristics from the services I query (even though I'm only asking for a few out of each). On May 23, 2013, at 15:15 , Rick Mann <rmann@latencyzero.com> wrote:

I'm sending a request for characterstics like this:

NSArray* chs = @[ kCBUUIDCharacteristicIPAddress, kCBUUIDCharacteristicAuthToken ]; [self.peripheral discoverCharacteristics: chs forService: service];

I get back two Characteristics, but they are not the two I requested. They are the other two of the three defined.

In a subsequent call, I ask for three Characteristics of a different service:

NSArray* chs = @[ kCBUUIDCharacteristicJoinSSID, kCBUUIDCharacteristicJoinPassphrase, kCBUUIDCharacteristicWiFiCommand ]; [self.peripheral discoverCharacteristics: chs forService: service];

But I get back all nine characteristics defined in the service on the BLE112.

I send the GATT Service Changed (0x2A05) notification on connect every time.

Any ideas?

This is on an iPad 4 (Lightning Connector).

Oh, and the Simulator really sucks at connecting, even after being reset.
