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.
