[WP8548] Date Offset

Hi,

I’m using a Mangoh Red with a WP8548 chip.

The system is in the field. I can’t access it remotely.

The date is shifted by 49 days and 17 hours or 2^32 milliseconds.
it looks like a counter. Has anyone encountered the same problem before?

Thank,
Jérémy

have you set the time sync?

Hi,

The time was in sync and I installed a coin cell battery for the RTC.
It’s just that one day the system lost 2^32 milliseconds.

How many modules are seeing this issue?
Any reproducible steps?

Hi,

Currently only one in five, but last week another system had this problem, but after 3 days the problem resolved itself.

Our system wakes up every 6 minutes. It retrieves some data from an external sensor and switches back to ULPM mode. And every two hours he sends a file with the data by FTP.

When the system was in the offices, we saw no date issues.

Thank,
Jérémy
