I've had a look around and I can't find anyone with a similar setup to what I'm looking for, maybe someone here can help?
I want a Pi3 that I can carry with me and control from my phone (terminal interface only) for mobile network diagnostics, access to SSH servers etc. Because it's coming with me SSH via a Dyn-DNS doesn't seem to be an option, due to relocation and Wi-Fi passwords etc. Ideally I want it to operate in environments without a network connection. I'd like the Pi to run on Kali, but any distro is fine!
My perfect scenario would be using the bluetooth to connect to the PI from my phone, leaving my phone able to connect to the Wi-Fi wherever I am.
