C1 does not work with ultra_simple tests

[alfem]

Hi!

I am testing a brand new C1 Lidar.

I downloaded master branch today, compiled it in a Jetson Orin (Ubuntu 20.04) and then

sudo ./ultra_simple --channel --serial /dev/ttyUSB0

After a second, this message comes up:

Ultra simple LIDAR data grabber for SLAMTEC LIDAR.
Version: 2.1.0
Error, cannot bind to the specified serial port /dev/ttyUSB0.

Lidar does nothing at all (no noise, buzzs...). Only a green light in the serial-USB board lights up.

Any clue?

Tested in windows, with robotstudio, and lidar works. Also tested sdk in a linuxmint laptop, and does not work.

It's trying to bind to an IP and it doesn't appear that they've added support for serial ports. custom_baudrate is the only app that works, and only if you pass it the default baud of 460800

#128

I was able to get the sample apps working by applying the patch in #125 and running custom_baudrate first

$ ./output/Linux/Debug/custom_baudrate /dev/ttyUSB0 460800

The baudrate detected by the pair is 0 bps. Error: 100.000 %
Warning, actual BPS error is too large. Communication based on this baudrate may fail.
Wow, we just communicate with the LIDAR using non-standard baudrate : 460800!.
