A single Android device can be used if:
(a) it has cellular data capabilities (Wi-Fi only tablets are not compatible)
(b) the Android device is configured as a Wi-Fi hotspot
(c) the VidiU Pro's Wi-Fi adapter is configured in Client mode to join the hotspot created by the Android device
The VidiU app for Android does not allow multiple Android devices with cellular data to contribute to the ShareLink stream when the VidiU is configured in AP mode; only iOS devices with the VidiU app can connect to the VidiU in AP mode and contribute to ShareLink.
