Welcome dxxpublic,
I'll just start by making sure I understand the situation fully. Please don't mind the questions that seem obvious.
1. When you say that you installed vox on your phone, I assume you mean VoxWav Free because you're referring to the antenna setting, but can you please confirm?
2. Did you for sure enable the TcpMic plugin in VC, and not the TCP plugin? It has happened many times that other users have confused the two different plugins.
3. If you enabled the correct plugin, did you restart VC after enabling the TcpMic plugin before testing VoxWav Free? (If not, try it.)
4. What do you mean when you say you "use the little antenna option" and don't do anything else. When you click on the antenna, what do you see? You *should* see a popup that tells you to pick a host IP, and then lists the IP address of the computer running VC. Then you should select that IP address.
Once you've done that, then the VoxWav title bar will show the IP address in parentheses beside the app logo, and you can start issuing commands
Is this what is happening? If you're only seeing "Pick a host IP" without an IP address listed, the most common problems are either:
a. the TcpMic plugin is not enabled in VC
b. wifi is not working on the phone (no LAN access)
5. Does your phone have wifi enabled/access to your LAN? (as opposed to relying on a 3G or 4G mobile internet connection)
