I want to connect ping sonar 180 to a 50 meter cable with the grove RS485 module and then recover the data by Arduino and send it via wireless to an Arduino connected via USB port to my PC on which I wish to receive the data with the ping viewer software. I first started by connecting the sonar dire…

Hi Traoré, welcome to the BR forums! Sounds like you’re working on a cool project. Are you using a ping2 sonar or a ping360? If you’re using the ping/ping2 single-beam sonar, you’ll need to use a converter to change the serial output to RS485 for your long range connection. Using a telemetry radio…

Hello Anthony Thank you for your reply, I use ping Sonar 180, Can you suggest a type of radio telemetry that can reach a range of 1 km? Thanks in advance

Hi Traoré - It depends what frequency / power levels are legal in your part of the world, but generally telemetry radios , especially with directional antennas, can achieve a 1km link that has line-of-sight without issues. Good luck!

Hello, Here is the radio telemetry module that I was able to obtain Link: https://www.amazon.com/FPVDrone-Telemetry-Transmit-Pixhawk-controller/dp/B074V6FKZR I connected the Sonar as follows: (Radio telemetry) TX —> RX (Ping1 Sonar) (Radio telemetry) RX —> TX (Ping1 Sonar) both in common mass…

Hi @MahamadouDr - Do you know what baud rate those radios are configured to communicate with? It sounds like your wiring is correct. You can verify the radios are functioning by connecting the TX to the RX on the device (non USB) side, and sending characters over the serial link from a terminal pro…

Good evening Anthony, How are you doing ? I was able to modify the baudrate of the Radio telemetry module to 9600 Baud, But on the side of the Ping viewer software I still can’t detect the sonar. But then I configured the radio telemetry at 115200 baud and there I was able to detect the sonar on…

Hi @MahamadouDr - As I said, with radios at 115200 it should function - glad it is! You could configure the Ping2 to use 9600 baud, and then change the radios - this might reduce the # of transmission errors, but would slow the communicatiosn rate further, by a factor of 12! The performance issues…

Good evening Anthony Okay I understand now, I would like to obtain these telemetry radios which seem to me to be of good quality, what do you think? https://holybro.com/products/sik-telemetry-radio-v3 Thank you very much for the helping hand.

@MahamadouDr Happy to help! Those look like much better quality radios, but they may still struggle with the data rate. 2.4ghz radios would work better, but have diminished range. Setting up an ESP32 unit to talk to Ping2 and directly to your computer may be another, cheaper option? Make sure to c…

Hello Anthony; Sorry for all this time without news; For reasons of availability, I stopped working on the project for a while. Currently I plan to take it again; I carried out a test this morning with two 2.4 GHz Lora modules; I was finally able to establish the connection with the sonar with my…
