Dexcom picked up restart

[MM2]

Did you check this post?

The last two G6 sensors have stopped working after 10 days exactly using xDrip+, but didn't used to

I received one 8G transmitter, which I haven’t used yet but will at the next sensor because my 81 transmitter is at 97 days and is flaking out (i.e. dropping bluetooth regularly). I just received my next transmitter, which is an 8H. The logical interpretation is that 8G transmitters have a serious bug and this is fixed in 8H, otherwise the early rev doesn’t make any sense.

What is first 3 char of transmitter?
