Command reference

Example:

AT+S.SOCKON=myserver,1234,t<cr>

AT+S. SOCKW: write len bytes of data to socket

AT+S. SOCKW allows to write data to socket. This command accepts data after the <cr> at

the end of the command line. The host is expected to supply <len> characters of data after

the end of the command line.

Note:

When the ok token has not been received is really important to handle properly the error

stage. In fact, the "at+sockw" command is not reentrant. If bytes are lost during data transfer

over the UART, the module remains in waiting stage for incoming bytes.

Arguments:

<ID>: socket identifier

<len>: data length to send (in bytes), up to 4096 bytes

Example:

AT+S.SOCKW=00,11<cr>

Test_socket

2.15

AT+S.SOCKQ: query pending data

AT+S.SOCKQ returns the number of bytes of data waiting on socket.

Arguments:

<ID>: socket identifier

Example:

AT+S.SOCKQ=01<cr>

DATALEN: 12

2.16

AT+S. SOCKR: return len bytes of data from socket

AT+S. SOCKR allows to read data from socket.

Arguments:

<ID>: socket identifier

<len>: data length to read
