![]() You can hard-wire your iPad to to the projector using a VGA or HDMI cable and the appropriate lightning adaptor. That happens too frequently to be viable. ③ I find that sometimes when there are lots of WiFi devices in a room all accessing the WAP (as is usually the case in a classroom) the AirPlay connection tends to drop out altogether. Its heft restricts hand gestures and I think, looks a bit awkward. ② The iPad is a little bulky to hold while presenting. ① Sometimes AirPlay can be a little laggy – especially if you have video in the Keynote slides. I’ve done that sometimes in the past, but there are four problems. You can AirPlay your iPad screen to an AppleTV, or to a computer running Reflector, AirServer or X-Mirage. I didn’t know that was possible! It makes presenting from an iPad a realistic option. This morning I discovered that I can do it over Bluetooth (not WiFi) from my iPhone. I’ll have to dive into what api they have made available.There are lots of options for giving a Keynote presentation from your iPad, most of which are sub-optimal. UPDATE 3: Apple released discovery over bluetooth ( link). UPDATE 2: PSU AirPlay App ( Mirror by Penn State) now on the iTunes App Store!! Now available as an Enterprise App located at ![]() ![]() UPDATE: Technical Q&A QA1753 from Apple was updated on for the iOS 7.0 release introducing “a new NSNetService property, includesPeerToPeer, that can be used to enable registration and discovery over Bluetooth”. Hopefully they will update their software in the future.įuture plans include looking at bluetooth discovery with iBeacons for locating devices. I contacted both companies but never got a way to hard code the ports when the application launches. This might had been an easier solution for podium computer installations, similarly to how we deployed Doceri. I was interested in using AirServer or X-Mirage, however both products used dynamic ports and couldn’t be manually registered. Penn State users are now able to locate and connect to registered AppleTVs using this app. I showed a few staff what I had working, and within a few months thanks to Sherwyn Saul and Ben Brautigam’s help with coding we have a working iOS enterprise app. I almost didn’t expect it to work but my first connection went right through and I had the first proof of concept in early September 2013. Some quick changes to the sample code and I had successfully proxied my first AppleTV registration to an iPad. It took me awhile to research, but I finally came across these two articles( 1)( 2) and the DNSSDObjects sample code from Apple. I had been using Network Beacon for years to proxy bonjour registrations and started to wonder if I could simply do the same thing running on an iPad. Keep in mind this was just on our test networks that actually still had bonjour enabled. This meant that I had to manually enter these bonjour registrations. ![]() I ended up using Avahi running on Raspbian( RaspberryPi) installed in the network closet next to the wireless controller at two campuses. but these solutions wouldn’t scale very easily and be cumbersome to manage. This also meant that the AppleTVs would not be on the same network as the wireless clients and I had to use a bonjour repeater/gateway. I decided fairly quickly that using 802.1x authentication wasn’t a feasible solution for deployment and decided to wire all AppleTVs using ethernet. Like many others I set up 802.1x authentication and found several problems, mainly the NTP service as well as how cumbersome it was to setup. The first problem to address was getting the AppleTV onto the network. Aruba AirGroup was also a consideration, however there were cost and management issues. During that time I investigated several Bonjour repeaters( 1)( 2), gateways( 3)( 4), and software products( 5)( 6). I worked with TNS, our telecommunications and networking solutions department, to set up several “test” bonjour deployments on separate SSIDs so we could determine the usefulness of the technology and help look at solutions. Our current wireless infrastructure, like many larger universities, is Aurba utilizing 802.1x authentication and Bonjour(multicast) disabled. This wasn’t a good enough solution for many who still wanted full iOS mirroring. Doceri, similarly Splashtop Whiteboard, provided some relief and made the use of iPads in the classroom finally possible. One of the most recent challenges I had was getting AppleTVs working in the classroom.
