We use 2016 May 11 AT non-SDK firmware.
We try to use the following AT command setting
then we try to random send data to server, and try to get the echo data from server.
(Half-duplex). Each time, we send the data less than 1460 bytes.
Our server is a simple socket code in linux, just like
n = recv(socket, buffer, BUFFER_SIZE);
sendbytes =send(socket, buffer, n);
In most case, the esp8266 module can get correct echo packet and report it to MCU.
資料都是小於1460 bytes.. server 都正確收到並 echo 回ESP8266 ...
But sometimes, error happen:
the server echo correct data , however, the esp8266 並沒有把所有data 回報MCU...
也有時候 回報的data 內容也可能會錯..
It seems that data loss between ESP8266 to MCU...
