SmartSonic™ MEMS Ultrasonic ToF Sensors

I am developing a distance sensor to measure distance between two items, each
equipped a CH-101 sensor.

As advertised, the CH-101 measures the distance from the sensor to an object by
time of flight measurement between the send and received echo

I would like to use the sensors slightly different. I would like to send by one (A) and receive
this pulse by the other (B) and returning the pulse from B to A to acknowledge. So no echo
measurement but send - receive measurement

I just learned about the new CH201. What are the differences in relation to CH101?
Only range extended to 5m?
Does CH101 also have an embedded DSP as CH201?

Dear all,

Hi, We are a water utility company in Australia playing around with CH-101 sensor. We were able to connect and use the Soniclink GUI application to get the waveform and run the Hello chirp program to get the values out using the dev kit. But our engineer needs the commands for communicating via I2C with the sensor using our equipment to operate different modes and get the distance values corresponding to each pings(all values corresponding to A-scan waveforms for each samples). We are unable to find any documentation with regards to this.
