Accessing a remote gpsd from local gpsd

[Nilan]

Hi

(Here LinuxPC_1 and LinuxPC_2 are two prototype boards running Linux)

Im running gpsd 3.16 in LinuxPC_1 and my UBlock GNSS evaluation kit is connected to thesame LinuxPC_1.
I start gpsd as follows
/usr/sbin/gpsd -S 6437 -G /dev/ttyACM0
It runs without a problem and and if I use gpspipe or gpsmon client tools in same LinuxPC_1, I can see data from my UBlock GNSS.

Even further, If I run gpspipe in another remote machine(LinuxPC_2) gpspipe -r IPoFLinuxPC_1:6437, I can see GNSS data from my LinuxPC_2 as well.

Then I want to run gpsd in my LinuxPC_2 and get its data feed from LinuxPC_1 gpsd.
I run gpsd in my LinuxPC_2 as follows,
/usr/sbin/gpsd -G -n tcp://LinuxPC_1:6437 (I tried tcp:// gpsd:// both)

Here are the problems I am facing,

When Im using gpsd version 3.16 on both LinuxPC_1 and LinuxPC_2 :
--------------------------------------------------------------------------------------------------------
I run /usr/sbin/gpsd -G -n tcp://LinuxPC_1:6437 command from my LinuxPC_2, and it can connect to LinuxPC_1 gpsd without a problem.
Connection is successfull, But if i run gpspipe -r from LinuxPC_2 it gives me,
{"class":"ERROR","message":"Unrecognized request ''"} error responce.


When I am running a different gpsd version (3.10 or 2.92) in my LinuxPC_2
----------------------------------------------------------------------------------------------------------------
I run same command, /usr/sbin/gpsd -G -n tcp://LinuxPC_1:6437 then it cannot connect to LinuxPC_1 gpsd.
It gives me following errors,

I would contact Eric Raymond, have a look at the gpsd link HERE
