Doesn't work at all for me? My time won't sync even with an internet connection. picocom -b 9600 -f n /dev/ttyS0 didn't do anything when I ran it? sudo ppstest /dev/pps0 gave the correct output as far as I can tell though. For Pi2/3 he said use make -j5 so I did a make -j5 sudo service ntp stop sud...

cgps -s is timing out on me with no fix. The status LED on the GPS module says it has a fix though. I had this issue last time they updated Jessie. Looks like they broke it again. :x Adafruit really needs to get on top of updating their tutorials. In the past I could run sudo cat /dev/ttyAMA0 and g...

The GPS has a lock at boot up and provides correct time at the proper sampling frequency (10 Hz).

Thank you for posting that info. I am going to try this out for myself. I have been wanting to try it but kept putting it off. It might take me a while though. I don't have the GPS module setup at the moment. That would be wonderful. Thank you for your help. I think it is a very important feature t...

As far as I know, the Pi will not get the time from the GPS module unless you tell it too? I have this one, https://www.adafruit.com/products/746 My Pi will not get the time from it. The onboard RTC is only used by the GPS module itself. You have to tell the PI to read from it. Did you do that? Oth...

Link to the GPS Hat you purchased? And a link to any instructions you followed to connect the GPS and the RTC. The link to the GPS hat is : https://learn.adafruit.com/adafruit-ultimate-gps-hat-for-raspberry-pi/overview The instruction to connect the GPS as a RTC is: https://frillip.com/raspberry-pi...

I am using a GPS module (Adafruit Ultimate GPS Hat) with built-in real time clock (RTC) connected to a RPi 3 (model B, running Raspbian Jessie). A python program is automatically executed at each startup and requires the time (from the clock) to be accurate in order to perform properly. The GPS modu...
