@BorjaOuterelo I am primarily interested in using micro-ROS on a bare metal STM32F103 for serial communication with a companion PC. But it would be beneficial if the same serial protocol and agent could be reused as a replacement for rosserial_arduino to communicate with the widely used Arduino platform.
I.e. if micro-ROS is not capable of running on an Arduino (ATmega328), the ROS community would need to look into alternative approaches like porting rosserial to ROS2.
