My girlfriend has a Medtronic 640g pump and I still hope that one day, she can use it to close the loop. I looked into the wireless communication (which can read the current glucose levels and send boluses), but apparently the protocol is encrypted. I would like to work at the protocol, but decrypting a wireless protocol seems too hard for me. But I still hope that some day, the Medtronic pumps will be hacked, too.
