Underwater sonar configuration

[Revu_Mac_Taylor]

Hello word!
My name is Alberto (Revu) and I have problems with underwater sonar.

Pixhawk 2.4.8
Transmitter: FST6
Telemetry 433mH

I got Kogger 2D sonar base from here:
SONAR 2D-BASE – Kogger
I set params like this:
KOGGER Underwater Sonar — Copter documentation (ardupilot.org)
And I get 0,37 cm …0,40cm…0,30cm… in a bathtub at home (Sweet water)

Well…When I have tested at a depth of 2 meters, the sensor keeps reading 0.47 … 0.37 … and I don’t know what else to try!

• First of all, I have problem here.

SERIAL2_PROTOCOL = 9 (lidar)
When… Ardurover 4.0 9 es RANGEFINDER.

What type I need to set ?

On my project, I want to graph the seaside from a small port.
I will be very grateful for all the help you can give me.
Best regards,

Probably 9. LiDAR and Rangefinder do provide the same kind of information.

[Revu_Mac_Taylor]

In agreement. I have done tests, but I have a thousand doubts.
How do I modify the sensor Hz to measure meters?

I only need to plug and play like this?

I read “configuring the echosounder” I need it?
The module should be configured before it is connected to the ArduPilot.

[amilcarlucas]

yes, you need it. You need to configure it before connecting to ArduRover. And you probably need to use the ArduRover 4.1.0-dev version.

[Revu_Mac_Taylor]

Well, I have control and monitoring from Tablet. Tomorrow I will test on Pixhawk (NMEA) mode.

[Revu_Mac_Taylor]

Now We have some problems.

First, when I activate Telemetry Pixhawk said “Error 0x800”. Without telemetry works fine.

Another problem was sonarrange mark 0.0 today. No 0.3…0.27… nothing.
I dont know what more test and change.

[amilcarlucas]

You must have changed something. Think hard what it might have been, and revert it.

[Revu_Mac_Taylor]

Well… now ArduPilot Rover 4.0 with MissionPlanner is working perfect. Motor, servo, GPS signal, its ok.
But now I have a problem with underwater sonar. Still marking 0.0 rangemeters…
serial2_protocol is perfectly setted… i dont know !

[Revu_Mac_Taylor]

Finally, It was a bad connection!!

I got depth. Now I need to know what parameters modified on my underwater sonar:

[Revu_Mac_Taylor]

I got it !! Now I have depth on meters and nice survey !!

Hi
How did you solve the problem on pixhawk?
I met the same problem. I have finish configuration on kogger api and pixhawk. However, i got no data on pixhawk

i cannot get any data from sonar range have you some suggestion ? from android app i can see something only from echogram but no range model used 2d-base , tried different settings /baud / ardu versions thanks
