ASSIGNING PORT FOR LIDAR AND ESP

It is crucial to assign ports for LIDAR and ESP because both of them receive random ports in ttyUSB format.

Use This command to identify port and characters after “usb”

dmesg | grep ttyUSB

sudo nano /etc/udev/rules.d/10-usb-serial.rules

SUBSYSTEM=="tty", KERNELS=="1-1.4", SYMLINK+="ttyUSB_ESP"
SUBSYSTEM=="tty", KERNELS=="1-1.1", SYMLINK+="ttyUSB_LIDAR"

For loading the new rules:-

sudo udevadm trigger

By running the next command in the Terminal, you may verify the new names you just made:-

ls -l /dev/ttyUSB*
