+ok=<mode><CR><LF><CR><LF>
Set Operation
AT+UARTTE=<mode><CR>
+ok<CR><LF><CR><LF>
Parameters:
mode:
fast: No free-frame trigger time, the uart data may be break into two fragment

4.2.2.19.
AT+SEND
Function:
Send Data to SOCKA at Command Mode
.
Format:
AT+SEND=<data_lenth><CR>
+ok<CR><LF><CR><LF>
Parameters:
data_lenth: Lenth of send data. Range: 0~1000 Byte
The UART port will wait 3 seconds for input after this command is sent OK. The data received
from UART port is sent to SOCKA. If the interval of two bytes is more than 10ms, the data will be
sent instantly.

Parameters:
data_lenth: Lenth of receive data. Range: 0~1000 Byte
timeout: wait for timeout, 0~10 sec
data_content: contents of receive data.
If not receive any data in 3 second, then feok=0.
