I am trying to connect the Sonar to an Nvidia Jetson TX2 Development Board but I can’t seem to be able to get it working. I’ve tried connecting the jumpers to serial UART /dev/ttyTHS2 port on the Jetson and running simplePingExample.py from here GitHub - bluerobotics/ping-python: Python scripts and…

Worth noting: I have successfully performed UART communication in the past on the Jetson using the same /dev/ttyhTHS2 port Also worth noting: I haven’t been able to get the Sonar working on any device since I got it yet since I don’t have the BLUART converter, and using my third-party converter has…

HI Yousef Just curious…what else have you got integrated with the Nvidia Jetson? Thrusters, Lights, Depth, IMU, GPS, Camera?

@yuzo-san , in order to make sure the sonar and the serial converter works, can you please try to connect to the sonar using our ping-viewer application? Try also another usb cable.

Hey! Thanks for the response. Actually I’ve managed to figure out what the problem was and got it working. I tried using a different 5V VCC pin on the Jetson other than the one in the UART port and it worked. Seems like the one in UART was working on 3.3V or something. As for the serial converter, I…

We’re yet to get to the hardware assembly phase, but yeah the plan is to have all of that minus the GPS. However we’re also using a Pixhawk, so that’s where the Depth Sensor is gonna go, and the Pixhawk will be connected to the board itself. As for the IMU it will likely be connected to an external …

There are IMUs inside of the pixhawk. [image] yuzo-san: However we’re also using a Pixhawk, so that’s where the Depth Sensor is gonna go, and the Pixhawk will be connected to the board itself. As for the IMU it will likely be connected to an external micro-controller that communicates with the …

yeah I’m aware. However, we’re hoping to use an external IMU as well and perform sensor fusion between both the internal Pixhawk IMUs and the external one.

Keen to hear how you get on as I am actively going down the Nvidia Jetson Nano route…

Hi bro, Can you please explained how you connect it? I trying to hookup the sonar with the jetson tx2 and i having the same problem. Im using the BLUART.

Hello @khangydt , as a starting point in troubleshooting, are you able to use the sonar with the ping-viewer application on a normal desktop? What is your current situation?
