With users typically having both a smartphone and a tablet, and now even having wearables, I am curious about which technologies can be used to have Xamarin.Forms apps on these different devices (iOS, Android, Windows) communicating with each other, both with and without separate servers.
Without separate servers, I am particularly interested in locating any samples that show how to code peer-to-peer communications (whether Bluetooth or otherwise) between nearby devices, such as a tablet communicating with a phone, or a phone with a wearable etc. Ideally, I would be looking for something that allows nearby (let’s say in the same room) devices to communicate even if in a dead-zone for mobile signals.
Any thoughts or samples much appreciated.
