The serial port currently supports TCP/UDP/COM communication, but there is still a lot of work to be done to improve the ultimate goal, such as MQTT and proxy forwarding. However, these functions will be reflected in the form of plugins in the future.
1.Classic COM type
The common low-end sensors in the current Internet of Things generally support the RS485/232 protocol and transmit simple latin1 text content. Some embedded development boards also frequently use it for device information output.
2.TCP network devices are relatively common, such as serial servers, whose function is to forward RS232/485 data to the internet.
3.UDP network devices are commonly used in devices with high real-time data requirements within the local area network, such as autonomous driving LiDAR devices.
