OK, this is only tangentially related but it has been on my mind lately and I need to rant:
I am T1 diabetic. Over the last decade, a LOT has happened to improve my life, especially in regards to no longer needing to check glucose levels with blood, as glucose sensors you wear on your arm have become ubiquitous.
It started with a dedicated device that you needed to hold up to the sensor to get a reading (much nicer than pricking your finger) to that sensor being able to notify the dedicated device of high/low glucose values (yay! Sleep through the night, knowing you'll be woken up if something is wrong) to the sensor now constantly streaming glucose values to your phone.
Which is fantastic.
In theory.
In practice, there are two companies making these sensors (OK, there's a couple more, but they suck way more and are much less commonly used).
And both of their closed-source apps suuuuuuuuck. They do the bare minimum and nothing more. (Actually, it's worse than that. Ask me if you want to know. It's its own rant.)
Then there's xdrip+, a FANTASTIC app made by diabetics for diabetics. Instead of just showing you "this is your glucose" and sounding an alarm, once, when it's required, you can (just off the top of my head): Set an arbitrary amount of alarms with their own behaviors, which can be configured to vary by time of day; show the glucose everywhere (notification, lock screen, home screen,...); mute alarms for a custom time; do not sound an alarm if you're trending in the correct direction fast enough; do not sound the alarm multiple times if your are jittering around the threshold; notify other people automatically in case of emergency; and roughly 1000 things more. The app is well maintained, and of course open source.
Can you guess what the problem is?
That's right, manufacturers disapprove of using this app. For the worse one of the two sensors mentioned, the community reverse engineered the communication and it is now working perfectly with the app. For the better sensor, they can't and won't due to fear of legal repercussions.
It's my health. And I need to decide between worse hardware and useless software.
There's no technical reason for this. I dream of the EU passing a law that requires manufacturers of wearable medical devices to publish the comm protocols and to legitimize use of third party software.
Rant over.
That fucking sucks, and as someone who wears hearing aids it’s very relatable. Hearing aids are an investment that last about 5-10 years. As a teenager I got some demo units, then when I absolutely couldn’t keep them working anymore about a decade later and had the money I upgraded them.
In practical terms this is about 15 years of advancement, and it shows. Gone are the days of molds of your ear, replaced by little domes that rest in the canal. But more relevant to the story, you used to have about a week per battery, and very little tech beyond some computation, volume adjustment, phone mode, etc. To turn them off you’d take out the battery.
My current ones didn’t have options for removable batteries, only rechargeable, nor for if you have Bluetooth. You can control volume on the device and that’s it, the rest is in an app. Now overall this has been better than I thought it would be. Tv gets beamed into my ears, as do phone calls. My batteries never die unexpectedly.
However, I hate that app. Partly it’s having to pull out my personal phone at my desk to turn my ears off (open offices are the root problem but sometimes I just can’t do sound at the moment, a common experience for the hard of hearing). I also dislike how there’s no custom naming for modes (meeting mode is called church mode because hearing aid manufacturers don’t understand that not all deaf people are elderly).
But mostly it’s the damn Bluetooth, that wonderful terrible Bluetooth. There is no “search for new devices” option, it happens automatically when removing from the dock/charger as part of turning on. But worse than that there’s no “forget device” option. And any time a device sends messages to the hearing aids it prioritizes most recent. This is a dangerous combination with apartment living. It’s unlikely to go bad, but for me it did and holy hell it was frustrating to have less control over my medical devices than headphones. I couldn’t wear my hearing aids at home until my audiologist got in contact with the manufacturer and reset the devices because randomly my tv, audiobook, or amplification of my wife’s voice would cut to my neighbors device where they were clearly frustrated because they’d be turning it off and on and I’d be swapping my device in app and it’d get switched back as new device tries talking… It was clear that the designers were too afraid of the users breaking things by having control to allow us to fix things that “just worked” their way into a real problem. And if I weren’t a technologically skilled young woman I probably wouldn’t have been able to sufficiently describe the problem to get it solved
You just described every problem I've ever had with my Bluetooth headphones... I'm just about ready to throw them out because I take meetings constantly, and somehow my headphones are never connected to the right thing...
I hate Bluetooth with a passion, and I'm so sorry you have to deal with that for your hearing aid.
