Autosend Data by Watermark and by Timeout Iteraction
Let's configure a socket #3 data storage watermark to 3 bytes and socket autopush timeout to
1000 (1 sec).
AT+MIPSETS = 3,3,1000
OK
+MIPSETS: 3,0
Write 4 bytes of data (8 bytes in encoded form) to empty socket #3:
AT+MIPSEND=3,"61626364"
OK
+MIPSEND: 3,0,1371
A +MIPSEND unsolicited response returns 1371 empty bytes value - it means, that only one byte
(last byte) was stored, because first three bytes was sent as result watermark reach. The last byte
will send when autosend timeout expired (after 1000 mS). The remote side will receive two
packets of data:
