We were planning on using the date and timestamps from GGA and RMC as the base for our system clock. Can we trust that the values in those messages are valid and up to date even when the device has very poor or no reception?
which GPS module are you using?
SL869. Unsure about the firmware version though.
My suggestion if you want to be sure to have a valid data and valid time is to read this values after you have a fix.
please when you reply on this add also firstname.lastname@example.org on email loop.
I will reply from it, it’s our technical support website.
I just tried with one of our devices and got this timestamp:
TIME STAMP: 1397718673
DATE (M/D/Y @ h:m:s): 04 / 17 / 14 @ 7:11:13am UTC
This was last thursday which could make sense. It has been either turned off or being connected without an antenna indoors since then. I guess that ruins my plans for using the GPS as a clock source. We’ll figure something out 🙂
Btw, I’m replying via the forums so I can’t add additional CCs 🙁
Moreover remember if you want to open a ticket, for the future, can also write directly to email@example.com. It is the other website we use in order to do the customer support.
Nevertheless is good to have the answers here if people choose to use the forum, the community will appreciate the readily available answers and solutions..
of course I’m tring to reply also here and on tsemea, so there is the possibility to find some easy information for other customers also.
