How do I access just the gps.latitude property? #144

Open khunkovic opened 7 years ago

khunkovic commented 7 years ago

when I try this.

var arDrone = require('ar-drone'); var droneClient = arDrone.createClient(); droneClient.config('general:navdata_demo', 'FALSE'); // get back all data the copter can send droneClient.config('general:navdata_options', 777060865); // turn on GPS

droneClient.on('navdata', function(navdata) { console.log(navdata.gps.latitude + ', ' + navdata.gps.longitude); // do stuff with the GPS information.... }); droneClient.takeoff(); .....

I get this error C:\data>node gpsLog.js C:\data\gpsLog.js:8 console.log(navdata.gps.latitude + ', ' + navdata.gps.longitude); ^ TypeError: Cannot read property 'latitude' of undefined at Client. (C:\data\gpsLog.js:8:27) at emitOne (events.js:96:13) at Client.emit (events.js:188:7) at Client._handleNavdata (C:\data\node_modules\ar-drone\lib\Client.js:194:8) at emitOne (events.js:96:13) at UdpNavdataStream.emit (events.js:188:7) at UdpNavdataStream._handleMessage (C:\data\node_modules\ar-drone\lib\navdata\UdpNavdataStream.‌​js:73:10)

if I change 1 line of code I get back all gps data. I just want the latitude. console.log(navdata.gps);

Hi - if you want the nav data, I think you need to change line 3: 'FALSE' to 'TRUE'

khunkovic commented 7 years ago

I'm getting nav data. I'm getting all of it in fact when I use console.log(navdata.gps); What I want to do is just isolate the latitude data. so that it can be saved to 1 variable and used in making a decision. Fyi. general nav data FALSE makes it return everything. general nav data TRUE will limit the data. Does anyone know how to only return the navdata.gps.latitude ? this article says its possible however it does not seem to work this way. http://stackoverflow.com/questions/24170884/get-gps-data-from-ar-drone-2-0

With a small mod adding a try catch block I get error, then data then error. Is this a bug? the gps data only transmits for a while. then it quits.

var arDrone = require('ar-drone'); var droneClient = arDrone.createClient(); droneClient.config('general:navdata_demo', 'FALSE'); // get back all data the copter can send droneClient.config('general:navdata_options', 777060865); // turn on GPS

droneClient.on('navdata', function(navdata) {

try {     console.log(navdata.gps.latitude + ', ' + navdata.gps.longitude); } catch(err) {     console.log(err.message); }

});

output.

can you print out navdata & navdata.gps?
