You are right, i'm looking for some notification that would indicate that the device has stopped emitting data.
Is there a way to configure the timeout time or to get the time elapsed since the last gps data ?
I have setup a GPSd and taken a look at the JSON output but I don't see anything about my device going silent.
Furthermore, is there a easy shell GPSd JSON interface to communicate easily.
I have used gpspipe -w to get the JSON output and connected to GPSd via telnet. Is there other means ?
Can you send request to GPSd with gpspipe ?
