Hi sanjeev,

 Currently there is less time to migrate to 3.19, once the issue got fixed, we will migrate to 3.19.  Let us know which step is missing in 3.16 because of which values are not getting passed to libgps client.

Thanks & Regards,

Sharmila, can you please switch to a current version of gpsd?  3.16 is over three years old, and the data structure you are trying to modify may no longer exist in a recognisable form.

If you use git, you can

I am using gpsd 3.16 version base source code. I  kept the 3 parameters
(velN, velE, height) in fix_t structure. I am able to receive the client
buffer like before and able to see my parameters , but in my application
I am receiving unexpected data.

Note : In fix structure all the values I am getting properly but
additional 3 parameters what I have added which is getting invalid data
and the fields below the fix_t structure are filled with invalid data
including status field which is getting zero or some big numbers.

I am attaching the patch for your reference, please provide some input.

Thanks & Regards,
