App-to-App communication from PC to Mobile Device

Unity Engine
1

Hey all,

We’ve got 2 devices, a PC and an Android (or iOS) device. The PC is running one app, and needs to receive messages from an app on the mobile device, 2-way communication would be great, but not essential. We’ll be taking this demo around to multiple places and needs to be fairly mobile. (PC required to run a VR headset, it’s a laptop)

There are a few ways we’ve looked at:

  1. Network connection over wi-fi: This is our fallback, but we don’t want to haul around a router and deal with wifi signals when we demo the product.
  2. Bluetooth connection: Looks technically complicated with Unity, and we’d want it to work for both iOS and Android
  3. USB connection: Looks even more technically complex

Any thoughts on best practices? Time is a factor, we’re looking to get a handshake happen within a few days and I’m not a strong developer, only been working with unity/professional coding for a few years. Another thought would be running everything through one device, so long as we can hook up the VR display with a touch interface.

Actually, just had a thought, turning on the tethering of the mobile device to make it act like a router. Now I just need to figure out the IP address of the device when it’s tethered.
