Hi, I'm working in a project where some clients are already configured to get localization data from gpsd. I'm in charge of creating a piece of software that would communicate with gpsd as if it was a GPS device, so these clients would be able to get this information from the same gpsd client interface, and in a frequency slightly higher than 1Hz. Based on gpsd manual pages, it was decided my "GPS device" would communicate to gpsd through UDP or TCP feed using NMEA sentences. The sentences are:
GGA +-------------------------+ ZDA +------+ TPV +--------------+ | my simulated GPS device | -----> | gpsd | -----> | gpsd clients | +-------------------------+ GST +------+ GST +--------------+ VTG ATT OHPR I have a first implementation of this idea, but I'm facing some problems which I would like to discuss. For information, I'm using gpsd-3.17 installed from Fedora 29 default repositories. I'm attaching some log files to help understand the problems.
Best, Ellon |
