Chrony doesn't receive any signal from the PPS socket (unreachable). I 
don't have the real value available right now, but I can recreate a 
setup in a few days if needed.

The gpsd documentation says :

"To get chronyd to connect to gpsd using the more precise socket method 
add this to your chrony.conf file (replacing ttyXX with your device name)."

So, my device name was...hmmm my gnss receiver is available on ttyACM0, 
so let's put "chrony.ttyACM0.sock" inside chrony.conf.

But "chrony.ttyACM0.sock" seems wrong.


As Perhaps this would be clearer :

"To get chronyd to connect to gpsd using the more precise socket method 
add this to your chrony.conf file (replacing ttyXX with your PPS device 
name ; if your pps is /dev/pps0, replace ttyXX with pps0)
