Arduino for STM32

I use it for my GPS, and I have called it in void setup. What I'm supposed to do to make the HW serial not blocking each other?

I'm doing a little project using STM32F103C8 for a GPS tracker system. I'm using GPS Neo-6m and SIM800L to send GPS value to the user phone number every 5 minutes. For your information, I'm using this core: [https://github.com/stm32duino/Arduino_Core_STM32] and my development environment is Arduino ...

Hi everyone, my name is Dini and I'm from Indonesia. I'm an electrical engineering student. Currently, I have a little project using STM32. My project is a real-time GPS tracker system, usually, I use the Arduino family for my project but I wanna learn something new by using STM32. I have been start...
