Cant receive GPS data

[shehroze37-zz]

Hi I have tried the following code however it just returns undefined for couple of time and then doesn't output anything
whats the problem here ?

var arDrone = require('ar-drone');
var arDroneConstants = require('ar-drone/lib/constants');

var fs = require('fs');

function navdataOptionMask(c) {
return 1 << c;
}

var navdataOptions = (
navdataOptionMask(arDroneConstants.options.DEMO)
| navdataOptionMask(arDroneConstants.options.VISION_DETECT)
| navdataOptionMask(arDroneConstants.options.MAGNETO)
| navdataOptionMask(arDroneConstants.options.WIFI)
| navdataOptionMask(arDroneConstants.options.ZIMMU_3000)
);

// Connect and configure the drone
var client = new arDrone.createClient();
client.config('general:navdata_demo', true);
client.config('general:navdata_options', navdataOptions);

client.on('navdata', function(navdata){
console.log(navdata.gps);
});

What version of the firmware is your drone running?

[shehroze37-zz]

Its 2.4.12

It might be a few days before I have a chance to test, but I wonder if it's a firmware version issue--just because I've seen something similar happen before when a new version of firmware started sending GPS data in a different format. I think 2.4.8 is known to work with the GPS, but you might have to hunt around to find a copy of old firmwares.

I have downgraded to 2.4.8 but still the same output

What kind of ardrone are you using?

Its a normal parrot ardrone 2.0

The normal ardrone 2.0 doesn't come with gps - only the gps edition comes
with it built in. You can get the flight recorder to plug in that gives you
gps data.

I did the test with the flight recorder

[Talamantez]

The other nav data prints out fine

[Talamantez]

have you seen the issue "Activate GPS navdata #75"?

"Even with the Flight Recorder GPS accessory, from a cold boot the
AR.Drone doesn't send GPS data as part of navdata."

#75

Hi @wiseman !!
I have Big problem! Please help me...
I'm using ARdrone1.0...I attatched gps to my ardrone. And i tested it using Arduino and linux....
but I don't know how to get data using Visual studio(c++).

1. Do you know how to get data from Ardrone 1.0??
2. And can you expain ZIMMU_3000 ?? is it similar with gps?
3. Is it right that the gps data are included in navdata?

size of data are just 12 in my program, so I'm very confused.
Thank you!

[wiseman]

Sorry, @lwsang13, this code isn't compatible with AR.Drone 1.0 and I don't know anything about it.

Hi @wiseman, @Talamantez ,

Long shot since it's been so long since you've worked on this, but I can't seem to get navdata either. Following issue #75 and #94, and running the exact same firmware (2.4.8) and gps firmware (4.1.2-P6), I still get essentially empty gps navdata. When printing navadata.gps.nbSatellites at every navdata event, I get just 0's.

Any ideas?

Thanks

[wiseman]

Just to be clear, you do get navdata, and the GPS navdata, but the GPS navdata basically shows that it's not receiving any satellites and it's not getting a GPS fix?
