Hello everyone,
I’m facing an issue with my Ping Sonar. Water has entered the sonar, and as a result, it has stopped working. Here are the troubleshooting steps I’ve already tried:
- I used Ping Viewer to diagnose the issue, but no readings were detected.
- I’ve attempted several code configurations on my Raspberry Pi, both with and without a TTL converter, but unfortunately, nothing has worked so far.
Has anyone else faced a similar issue, or does anyone have suggestions on further troubleshooting? Any advice would be appreciated!

Hi @Harshada -
Checkout this [guide](https://bluerobotics.com/learn/ping-repair-guide/)!
If water has entered the sonar and it ceased functioning, then the electronics are likely damaged. Please reach out via our support [form](https://bluerobotics.com/contact/#contact-us-form) with the relevant order number.
We have only heard of leaks with the Ping2 sonar when the cable was damaged or improperly modified…

Hi Tony,
Thanks for your attention.
I reconnected the SONAR with the Arduino Nano, and the LED blinked, confirming the connection is proper. I also verified that the RX and TX are connected correctly, but the output still says ‘Please check TX and RX pins.’ Any suggestions on how to resolve this issue would be greatly appreciated.

Hi @Harshada -
Sometimes swapping RX and TX will do the trick - they are often connected backwards!
A single blink does not indicate the connection is necessarily “proper”…

Hi @tony-white
Thank you for your response.
I tried swapping RX and TX, still facing the same issue, it is just initializing the SONAR and not able to get any reading. Any suggestion would be appreciated!

Hi @Harshada -
If you’ve followed the steps in the ping repair guide that was linked, please use the support form to continue the discussion - your hardware is likely damaged. A LED blinking on the Nano does not necessarily indicate the Ping2 is functional! Have you opened the Ping sonar and observed the LED behavior there?

Hi @tony-white
Yes, I opened SONAR LED blinked during initialization. However, after that, it only showed “Please swap RX and TX.” I swapped the pins as suggested, but the issue still wasn’t resolved. Any advice on what to try next?

Hi @Harshada -
If water has entered the sonar previously, and it’s not communicating no matter how the wires are connected, it is likely broken and inoperable. Sorry for the news!
Feel free to use our support [form](https://bluerobotics.com/contact/#contact-us-form) to report the problem, including whatever modifications led to water entering the unit.
