This post comes at a perfect time for me, as I'm currently documenting the undocumented API of Ubiquiti's Airview2[1] device, a cheap ($39, 5 years ago) 2.4GHz spectrum analyzer USB stick, which they've now stopped selling and abandoned in every way. Just the other day I was pondering who to contact to determine whether my current method of figuring out how the undocumented API works (typing command guesses over the CDC-ACM serial interface in gtkterm) puts me at risk, but it doesn't look like it. I'm not dumping the firmware and don't have a copy of it, not decompiling the original software, there is no access control on the interface, no encryption, no handshake, no EULA on the hardware itself. Seems that I'm in the clear from what I can tell. I've gotten enough of the commands documented that I've been able to write a library based on what I've learned, and I'm hoping to publish my documentation and the code soon. It's been quite fun to figure out how it works so I and others can actually use these things in other software :) [1] http://dl.ubnt.com/newsletters/0112.html http://dl.ubnt.com/newsletters/0112.html
