I have tested with "meshcore-open", version 7.0.0+8, on Android.
When I connect to a companion radio via TCP, there is an input field labeled "IP Adress". But it not only accepts an IP address, but also a hostname (to be resolved via DNS, in this case my local router's DNS).
So, the input field's name is wrong and should be changed, e.g. "IP Address/ hostname".
