|GCM w/ WiFi only tablets||Anil Gorthy||10/15/12 9:57 AM|
I have a use case where I need to update hundreds of tablets which are wi-fi only with my app and I want to use GCM to accomplish this goal. However, what I could not figure out from the docs is if I can register a wi-fi only device either w/ the IP (which might change based on the location) or using the development device ID or the wi-fi mac address. Which of the three that I mentioned are reliable ways of sending notifications to update w/ a newer version of my app? If none of these are the right choices, what are my options since I can't have a phone number associated with these devices.
Thanks in advance!
