Since I have access to an iPhone I connected to the camera with the standard app from the AppStore checked that the Gear 360 is using the latest firmware.
I also tried to connect to the Gear 360 with my 6T just using the Google Street View app and again, while the phone will connect to the camera, it's like the phone won't recognize the device is there. It seems like an issue with the network settings of the phone but I can't seem to find a configuration that gets it to work. Since you said you have a 7T running the same OS, I thought you may have some pointers on what to try. Really anyway to connect the 360 to my 6T is what I'm looking for.
