Currently on my SL6087, the RTC is updated with the time from the GPS module. I find the RTC drifts, so the time is refereshed whenever I get a GPS lock. This all works fine for a bit, then after a while (generally after a few days of running) I cannot update the RTC using adl_rtcSetTime or via AT+CCLK anymore. Here’s and example of trying to put the clock back 24 minutes
I have a similar issue on FXT009, I am currently using firmware 7.46.
We update the time on all our devices on a daily basis for RTC to be always in sync with our server.
However I see issues where the time cannot be updated and the RTC changed to some odd date and time.
I currently have issues with 3 units out of 100+ devices deployed in the field.
One has its RTC gone to 24 hours behind
One unit to 12 minutes behind
One has its RTC gone to a few days behind
The third device was rebooted several times by our engineer on field and see no difference. This device was sent back to our office, which took 2-3 days to get to me in post. By the time I got here I couldn’t see this issue. It may be because the RTC battery has been discharged and so it allowed me to set the time after I turned it on.
Is this a firmware issue? If so why and when does it happen?
Is this solved in 7.52?
