EVM430-FR6043: Serial communication with Ultrasonic Sensing Design Center firmware

Part Number: EVM430-FR6043

I am using EVM430-FR6043 for prototyping.

USS app works for me. I can set parameters, record graphs etc.

I found the communication protocol for the firmware (UltrasonicGasFR6043_02_30_00_01, from

I would like to use my own app to communicate with the device, so I could use ToF data in my own Python application. I am sending a simple package to query the "Application version" (command 0x99), but I do not get any data back from the serial port.

Probably the serial port settings or package format is incorrect.

What are the right serial port parameters (baud rate, etc.)?

My test package looks like this: 04 99 00 00 00 00 00 9D 00

Does that look sensible?
