Re: Sending data from application to gpsd

[raaj lokanathan]

Hi Gary,

First of all the language, I am using is C.

Second is from the gps_send method, I can see it is invoking the gps_sock_send() method. This method is doing the writing part to the socket right?

But I am not sure which part of the gpsd.c receives the command which is being sent through the gps_send method?

Is it possible to open the socket using gps_open and write using gps_send. However as I said previously, I don't have a command to write. Basically I just want to right numbers to the socket. And then from gpsd I should be able to extract it and then form the UBX command and send to the UBX driver.

Hard to say without knowing where "here" is.  Which is why I gave you
several examples of how gpsd clients use it.  Your first criteria would
be the language you program in.

Then look again.  gpsd uses the same protocol over udp, tcp, sockets,
stdio, etc.

With enough thrust pigs can fly.
