Any statistics on the transmissions peed and fault rates for the implementation?

[shaoziyang]

It is implemented in pure Python, so the speed is not too fast. If programming in C language, the speed can be faster.

Because Python code efficiency is slightly low, if the time set too short, garbled code may occur. In ESP32, you may set bitus to 250 and charus to 600, in this case, transmitting a byte takes less than 3 milliseconds.
