This question is silly on multiple levels:

• You don't pick tools and then try to fit them to the problem. You specify the problem as well as you can and then identify the correct tools.
• "...for this I can't use Perl." Why are you asking this question in Perlmonks then?
• "...communicate to a server"..."over bluetooth or wireless lan"..."server process just interacts with...command line tools..." Pretty much every toolkit for mobile devices can communicate via bluetooth and/or wireless LAN and every language worth learning or using can shell out to utilize 'command line tools.' That is not a specification. That is like saying 'I need an elephant for my parade' only to be surprised when someone arrives with an eight inch toy elephant.
• "..what do I need to read up on..." I can help you here. Perl is not the right tool for your task. Your task requires someone to do your work for you and to help you do your research and thinking. There are many toolsets available out there that purport to do exactly that. You should use one of those.
