This doesn’t solve your firmware problem, but you can use Ping with an Arduino at 115200 baud if it has more than one serial port (such as an Arduino Mega).

Check out my example in this thread: [Ping Sonar and Arduino Mega - #4 by NickNothom](https://discuss.bluerobotics.com/t/ping-sonar-and-arduino-mega/6016/4)
