Re: [gpsd-users] Gps application stops transmitting data after some time

[lokesh kumar Nijalinge]

Hi Gary,

Currently I was setting  baud rate to 4800bps and using ' gpsd -b'. 
I am getting output when I use 'cat /dev/ttyS0 '.

Still need to connect Data In pin of GPS?

Thanks,
Lokesh

Obviously no data Out means nothing can talk to your GPS to change
settings.  That will be a PITA as you need to change things like
the serial speed.  4800bps is just not good enough.

If you have upped the GPS speed on another host, and use 'gpsd -b'
then no data out would not cause this.

Too low a speed could cause this (input buffer overflow).  Or voltage
mismatch on the Data In can cause this.

Which is why I suggested you try a USB GPS to eliminate those as
causes.
