Fix find PEPPER_IP
Currently found inside lhw_qi/activate. There are three problems to fix:
-
CTRL-C breaks the shell when searching -
The scan finds multiple of pepper's ips if pepper is connected through both wifi and ethernet. -
The IP is only saved inside an environment variable, which means processes where this hasn't been source (such as those launched with cmd) don't have access to it. One idea is to save the IP to a file.
