Ancient thread, I know. Since this thread started and ended long before the Seven + came out, I am wondering if there's any new info on this particular subject?
In my case, I was on day 11 today, so I had restarted my sensor once already (last Friday afternoon). I got '???' for some time this AM, and then a few minutes ago I got 'SENSOR FAILED.' I didn't think to check in here first, so just pulled it off and put on a new one, but I'm now wondering if maybe I could have gotten it to restart even after having done a Start Sensor on the same sensor once already? Anyone know?
Started a new sensor yesterday, and got Sensor Failed this morning. Have tried restarting it twice, and it goes into startup mode for a while, switches to "???" then finally gives "Sensor Failed". I've now done this three times. Am I beating a dead horse?
It would be nice to hear from someone in here who might be able to explain this for me.
I notice the following:
a) sensor failed, usually cannot restart, but stop and restart can confirm bad status. I have had not much success restarting and replace.
b) on the dreaded ??? display, I have been able to restart some sensors. Others I find that if I offset my fingerprick reading input by plus 10 points, sensor will run sometimes. My sense to save time and at same time try and recover sensor, I do following:
c) make sure your bg is stable on caveman machine and if so stop and retart sensor. If any hope ok; sensor will restart after 2 hours and may run. At least lost time is cut to 2 hours and if it does not start up after 2 hours, I replace it.
There seem to be no real good answers here and the lack of rational descriptive error codes and information make debugging sensor/system in any meaningful way virtually impossible. ( Users are too stupid and worse yet we would be signing our own death warrent with the lawyers by providing useful help out there.) At least that is my impression after 1 year 2 months 24/7 running. I may have missed something and if anybody out there has better data to share - please add.
Not to be cheaky, which dead horse are you beating? Dexcom or yourself?
For me that answer is usually both.
While the lack of helpful useful data my not have meant to have been cavilear, but for many of us driving nasty body situations, the lack of some explanatory help or guidance on operating seems short circuited by the tacit approval of the device as a trend following device and eliminates any responsibility at FDA or Dexcom. I may be wrong but cannot explain the black hole of useful user information on a complex device operating on a complex multi organ; multi-hormone human system. This is not a timex wrist watch.
As I and others note that when it works and one gets acllimated to the 2 hour start up and all the oddities and learns to "interpret" the data and weirdness as well as living with the idiosynchonies of the sensors and body chemistry interaction, yes by golly it can be very helpful and in some cases most critical indeed to diabetics.
Thank you for writing and sharing.
