I'm remembering the last-connected peripheral by storing the identifier in NSUserDefaults, then trying to retrieve that peripheral on the next launch. Store: NSString* uuid = self.peripheral.identifier.UUIDString; // Store uuid in NSUserDefaults Retrieve: NSUUID* uuid = [[NSUUID alloc] initWithUUIDString: inPeripheralIdentifier]; [self.cm retrievePeripheralsWithIdentifiers: @[ uuid ]]; But -centralManager:didRetrievePeripherals: is never called (at all, even with an error). Am I doing something wrong? Thanks! -- Rick _______________________________________________ Do not post admin requests to the list. They will be ignored.
