First of all thanks a lot for that amazing app, I have tested quite a few and it is by far the best one.
Now, I am using two android tablets as extra monitors for a windows laptop, and it's working well but thanks to a workaround.
I have assigned both tethered connections a fixed ip : 192.168.42.1 (tablet1) & 192.168.42.2 (tablet2)
What happens :
I turn usb tethering on and server ip appears on tablet 1 (192.168.42.1)
I turn usb tethering on tablet 2 and no server ip shows up (should be 192.168.42.2). If I try to enter this address manually, it will timeout.
Now given that configuration, if I turn off usb tethering on tablet 1, server ip will show up on tablet 2 (192.168.42.2). It will also keep showing on tablet 1 (192.168.42.1). Finally, if I turn back on usb tethering on tablet 1, both server IPs will keep showing and I will be able to connect both tablets.
I have tested with different phones and tablet and it keeps behaving the same. For exemple if I want to connect 3 devices, I will have to launch spacedesk on each device, then switch on USB tethering on each of these devices while the two others are switched off for the server IP to show up. Once I've done that for all devices, I can connect them.
Also, when I check the windows server agent, local interfaces are as expected (192.168.42.1 & 192.168.42.2) but the network connections (remote) tab shows my devices having the same IP address 192.168.42.129 with random ports. I guess this must be the default android usb tethering IP.
I hope I have been clear enough, not that this is a deal breaker, I really love this app and it's working great with that little workaround, but is there anything that can be done to sort this out?
