Antenna tracker with BeagleBoneBlue

So i do see my gps but no change in the /dev

(1st one was with the GPS 2nd one without it)

Hum…TRY
sudo modprobe usbserial vendor=0x067b product=0x2303

and run dmesg again,

if it works => you see an ttyUSB0 for example, you can add the above line into this file /etc/modules

Butit does not mean that this GPS works with ArduPilot…
.

Perfect, now i see ttyUSB0 !

But when i try to test my gps with : sudo /home/debian/GPS_AUTO_test -B /dev/ttyUSB0 i’ve got a segmentation fault.

Is it because the gps doesn’t work with ArduPilot ?

What you need to do is confirm that you GPS is sending good data.
Using SCREEN or MINICOM, look at ttyUSB0 and find the right baud rate an confirm that you can read the standard NMEA message. I never tested with GPS_AUTO_test, looking at code , it expect this message:
// Print the contents of message
hal.console->printf(“Lat: “);
print_latlon(hal.console, loc.lat);
hal.console->printf(” Lon: “);
print_latlon(hal.console, loc.lng);
hal.console->printf(” Alt: %.2fm GSP: %.2fm/s CoG: %d SAT: %d TIM: %u/%lu STATUS: %u\n”,
(double)(loc.alt * 0.01f),
(double)gps.ground_speed(),
(int)gps.ground_course_cd() / 100,
gps.num_sats(),
gps.time_week(),
(long unsigned int)gps.time_week_ms(),
gps.status());

So if you can read this sequence in the terminal, try launching the program (tracker) with the good port speed and signal type
NMEA is type 5
0:None,1:AUTO,2:uBlox,3:MTK,4:MTK19,5:NMEA,6:SiRF,7:HIL,8:SwiftNav,9:UAVCAN,10:SBF,11:GSOF,12:QURT,13:ERB,14:MAV,15:NOVA

I think i have a problem with the gps itself, i’m trying to make it work on my PC for now, will see on Beaglebone later !

I’ll keep you inform.

I tested my GPS this weekend, but i was unable to make it work even on my computer. I’ll buy a new one soon (probably an ublox M8N).

I have a question, to setup the connection between the beaglebone and my ground station (mission planner) to get the drone position, the easiest way is to get the data through the beaglebone wifi by UDP ?

@Eogrim

M8N is great and you can use the Magnetometer as the external compass.
Yes , the easiest is to use connman and connect to a WIFI Accesspoint, but its bulky in the field and may interfere with the RC. So generally we use 900 Mhz (or 433, depending where you are located) radio (25$ @ Bangood) to transport Telemetry or Taranis (FrSky) telemetry .

I wanna try wifi first and only if i have to many interferences i’ll change to radiolink.
But i actually have some problems with my interface wlan0 who has vanished for no reason. I tried to change my interfaces and few things but i didn’t manage to run it back.


Here is my dmesg :

It looks like you have a BBBlack Image loaded , or you used BBBMINI instructions to load your images…

Oups, how can i correct that ? Should i start from a new image ?

I suggest you start a new image, you can use this ‘‘recette’’:

Hello.
I have a simple question, so I did not create a separate topic.
I want to collect a managed model controlled by mobile communication.
An analog of a military drone.
Is there such functionality for the controllers, if so which ones?
I did not understand this for a long time, so I could skip something.
I really hope for understanding.
Thanks to all.
