Gregory's Server@djh Let's step back a bit here: Why on earth are people running criticial health controls on an android smartphone? This has nothing to do with "proper functionality", but it's the wrong platform for these kinds of apps. Critical apps needs an RT operating system, guaranteed resources, a watchdog, and more. And the pump shouldn't rely on bluetooth in the first place, it's not a protocol for safety critical communication.

@ids1024 @crepererum @djh In the end you work with hard dead lines for safety criticial operation: "If no packet, no hearthbeat received within X milliseconds, assume the physical emergency stop button has been pushed". Exactly same code path. If you don't get the physical emergency stop button right, you are doomed anyway.  @crepererum @djh yes, but that is all that people are being offered or able to afford. This is a systemic problem. Not a moral failing of someone who needs to take insulin. |
@crepererum @djh You might cry, but using Bluetooth for safety critical operation is pretty common these days. Well, and considering the poor quality of other safety critical components in such setups, the Bluetooth connection might often be the most reliable part of these systems. We have failed.
