Python sample codes don't works on TeraRanger Evo 15m

[Yuanbwcx]

I have noticed that the Python sample codes don't work on Evo 15m on a Raspberry Pi.

What I did

1. I connected the Evo 15m time of flight sensor to a Raspberry Pi 4B via UART
2. I checked that the sensor appears to be detected at /dev/ttyS0
3. I first tried to run python3 Evo_64px_sample_py3.py but I got an error saying that no sensor was detected
4. I specified the port inside the script. In particular, I edited line 131 of that file and changed it to

evo_64px = Evo_64px(portname="/dev/ttyS0")

5. Then I started to get data, but it all seems wrong and not having the correct encoding; it is stuff like

b'\x05\x16T\n'
Invalid frame length: 4

I would appreciate any help on how to resolve this.

Hello @Yuanbwcx

The sample code to use for the Evo Single Point sensors (3m, 15m, 40m, 60m) is "Evo_single_point_display_range_py3.py".

Cheers,
