@lupyuen DAS BLINKENLIGHTS
@tasket @caligari @lupyuen It's not difficult to follow a signal. Ransomware attacks aren't going to be far behind as some of those systems use multiple wireless sensors.
They are difficult to open without using a Dremel. I've cut myself a few times with Xacto blades trying to get through that thick sonic welded plastic shell. At least the app wasn't too difficult to peek at. White listing devices and some other things that might possibly be going on.
There has to be a way to get in without bleeding everywhere. ![]()

@tasket @lupyuen 1. To avoid extra controllers (cost, mobility); 2. To integrate with other services like online monitoring (not specifically cloud but dependant people); 3. To facilitate free market (user's freedom) . The other side is the why not? BLE is widely supported and in continuous improvement. Does a non standard or privative technology guarantee full security (protected against malicious people, in this case) on well-being devices?

@lupyuen Maybe not true now, but one thing I discovered about the dbus-daemon, when I studied it years ago for a company project, was that it could block the root user from using D-Bus. That might have unexpected side-effects.

@lupyuen I'd have to question why anyone's insulin pump is controlled by an android device OR bluetooth.
