TCP/IP: MIP Commands Using Cases
response contains an actual remote address/port
+MIPRUDP: 1,172.16.157.52,1200,0,2233
Data Encoding
An IRA data will be encoded before writing to a socket by +MIPSEND command for correct
special IRA symbols processing. The encoding means replacing a single byte of data by two
characters, containing the source data IRA code, for example:
IRA Source Data
IRA Hex Code
+MIPSEND Encoded Data
Parameter
NULL 0x00 AT+MIPSEND=1,"00"
LINE FEED 0x0A AT+MIPSEND=1,"0A"
"Hello" 0x48 0x65 0x6C 0x6C 0x6F AT+MIPSEND=1,"48656C6C6F"
According to the above, an encoded data character valid range is 0...F.
The same data format is used for +MIPRTCP and +MIPRUDP unsolicited responses.
Socket Flow Control
When a socket can't send data to the Network, +MIPXOFF unsolicited indication is sent to the
user, see "+MIPXOFF, Socket Flow OFF unsolicited indication". The +MIPXOFF indication
may appear as result of physical link dormant state as well. The following example shows socket
XOFF indication as result of physical link dormant state:
AT+MIPOPEN=1,9,1080,"www.yahoo.com",80,0
OK
+MIPOPEN: 1,9,1
AT+MIPSEND=9,"474554202F696E6465782E68746D6C20485454502F312E300D0A0D0A"
OK
+MIPSEND: 9,0,1344
AT+MIPPUSH=9
OK
+MIPPUSH: 9,1
