[gpsd-users] Cannot get data from daemon

I’m using gpsd 3.9 on an ARM embedded system.

My GPS is embedded on Cinterion PHS8 module.


I open the gpsd with: gpsd /dev/ttyUSB1 –n.

When I use ‘top’ cmd, it seems that it is opened correctly with SYS privileges.


I use gps_stream() only with JSON flag.

In order to perform the reading I use gps_waiting() with 50 seconds and then gps_read().


The problem is that I can’t read any data although I can see the data when I ‘cat /dev/ttyUSB1’.


Does anyone have any suggestions?


Thank you,
