"Web6. You receive ~67 characters, which at 10 bits/character, is 670 bits. Given that your timeout (parameter 4) is set to 10ms or 0.01 s, the average bit rate seems to be around 67000 bit/s. My guess is that you are transmitting at 115200 baud with some inter-character delay giving an effective bit rate of 67000 bit/s. " - Hal_uart_transmit对应标准库
