Thanks for reaching out for feedback
@HelenNicholas despite this doubtless being a rather stressful time for you.
I already commented in your original thread with my suggestion that the official LibreLink app just reads and provides real-time access to the sensor data (for other apps to consume), which I think then obviates many of the requests made here as they could be handled by 3rd party apps. I suppose there will still be a requirement for Abbott to provide a minimum viable product, though presumably what they have so far meets that in their eyes.
I'd suggest that your son tries (if on Android) the combination of Juglucco + XDrip+ to see what the CGM system could look like and compare that with the standard Librelink app offering. There are also Apple options, though I don't know off-hand what the options are.
Similar to others who have posted here, I also suffer from signal drop-outs, it would be interesting to understand why these occur. I had originally assumed that they were always hardware failures, but I sometimes get signal drop-outs which last from 15min to some number of hours (up to 8), and then the sensor comes back to life and works for multiple days. These are not simply sensor errors, but no sensor signal being transmitted at all. Debugging these problems is likely rather difficult to do, especially as looking at teardowns the devices are built using a companion chip which handles the Bluetooth comms (EM9304) so the fault may lie in the companion chip firmware.
My list of failure modes is here:

I also suffer from calibration problems with some sensors, which I think is because I don't have much fat on my arms so if I happen to choose the wrong spot for a new sensor I'll have ongoing problems with it. There's not much that can be done about this. I must, however, try a different area to see if that improves matters (even though it's not officially "allowed").
