WISMO228 TCP/IP AT Commands

Manual

Read Command

AT+WIPDATA?

NONE

Test Command

AT+WIPDATA=?

 if <protocol> = 1

Unsolicited response

+WIPDATA: <protocol>,<idx>,<datagram size>,<peer IP>,<peer port>

Caution: Using AT+WIP AT commands, when receiving several UDP datagrams on an IP bearer,

+WIPDATA indication is sent once for the first received datagram. Next indication (for next

remaining UDP datagram to read) is sent once the first datagram have been read (using

+WIPDATA command).

 if <protocol> = 2

Unsolicited response

+WIPDATA: <protocol>,<idx>,<number of readable bytes>

Caution: The value returned by <number of readable bytes> indicates that there is some TCP data ready

to be read but number of bytes returned might not be reliable. Moreover, using AT+WIP AT

commands, when receiving several TCP packets on an IP bearer, +WIPDATA indication is sent

once for the first received packet. The next indication (for the next remaining TCP packet to

read) is sent after the first packet has been read (using +WIPDATA command).
