18 px] [size=STM32 ESP8266 connection ali cloud, development board can send data to the server success and be read (see below), but down from the server sends the data to accept less than content, can know to data (see chart, according to the serial port assistant len is to accept the data length), what reason is this excuse me? Is really can't find where the problem is

this picture you can see a serial port communication is no problem of

this is single chip microcomputer to the server sends data, you can see received the correct data

here send 123... Such as data, below is the microcontroller receives, len only accept the two data and still not correct, other all have no
