Re: [gpsd-dev] GPSD for AOSP

[ABOU ZID Ahmed]

Hello !

 

Ok so to be more clear :

 

I would like to use GPSD deamon to read on /dev/ttyUSBX (ttyUSBX represents my USB GPS)

 

Here it’s what I’m using for my own Android GPS HAL : https://github.com/kconger/android-serial-gps-driver

I would like to replace this code by a connection with GPSD deamon on TCP socket instead. In summary, I would like to abstract the device connection with GPSD.

 

I know that GPSD is forwarding GPSD data (latitude, longitude, bearing, timestamp etc...) to clients.

 

I don’t know if you understand correctly what I would like to do.

It’s very simple but just need GPSd running on Android that’s all.

 

For that I just need to adapt the makefile for Android. But yeah, as sconst is not that clear... I don’t understand which .c file are you compiling only for GPSD (deamon).

 

So if someone can help me doing that, it would be great!

 

Thanks,

Ahmed

What do you mean by "GPS localization'?  gpsd only read from GPS

devices, directly or indirectly.

Once you say 'HAL', you are into an area I know nothing of...

 

Except I though HAL meant hardware Abstraction Layer, and no hardware

in sight.

 

And why not have the app directly connect to gpsd?

I doubt that is all.  Where will gpsd get its data from?  Why not use

the AOSP location API?

We do not know of such a thing.  If you write that, or find that, send

us the code.  We can give you help, but we have no expertise in AOSP

here.
