Support needed for RPLidar A1M8 interface

Hello, everyone.
I have two RPLidar A1M8 parts from you. I have been tryin to interface it with STM32F103 without success. They connect fine with a PC using the CP2102 bundled board, but they won’t connect with my STM32. The datasheet says it supports 3.3v TTL UART, which is what I have on the microcontroller.
Any assistance will be appreciate.
Thank you.
