Bluerobotics Ping360 Sonar and Waveshare ETH/RS485 Connection Issue

[omer_1]

Hello,

I’m trying to connect my Bluerobotics Ping360 sonar using a Waveshare ETH/RS485 converter, but I’m experiencing serious issues. I cannot see any sonar data in Ping Viewer at all, and in terminal programs, I receive only corrupted data. Below, I’ll explain the problems and what I have tried so far. Any help would be greatly appreciated!

Issues:

1. No Data in Ping Viewer

• Even though the connection is established, the Ping360 sonar does not scan.
• No sonar data appears in Ping Viewer.

2. Receiving Corrupted Data in Terminal Programs

• Since Ping Viewer does not show any data, I tried using terminal programs (RealTerm, etc.).
• In the terminal, I receive repeating, meaningless characters like this:

j6A Z5A J4A :3A *2A 1A 0A z7A 0D 00

What I Have Tried:

1. Checked Baud Rate Settings

• Initially set to 57600, then changed to 115200 baud, as required by the Ping360 sonar.
• I configured both Ping Viewer and terminal programs to 115200 baud, but it didn’t solve the issue.

2. Checked Waveshare ETH/RS485 Converter Settings

• I tested both “Transparent Mode” and “TCP Client Mode”.
• Ping Viewer still does not display any data.

3. Verified RS485 Wiring

• I suspected a wiring issue, so I swapped the A and B connections, but there was no change.

4. Tried Different Modes in RealTerm

• I switched RealTerm to “Hex + ASCII” mode, but I still receive only corrupted characters in the terminal.

Request for Help!

• I cannot see any sonar data in Ping Viewer—it does not work at all!
• I only receive corrupted data in the terminal.
• I have checked the baud rate, RS485 configuration, and different modes, but nothing has worked.

What could be causing this? Does anyone have any suggestions?

Hi @omer_1 -
Did you convert the Ping360 internal wiring to use the RS485 interface? If not, I hope that your tests have not damaged the default USB connection!
