Multi-Tech Systems, Inc. CDMA C1 AT Commands Reference Guide (PN S000478C)
This unsolicited response indicates an error occurred while attempting to connect a socket to it’s
peer, or that an error occurred on the socket after the socket was created. The AT+WIPCREATE
command immediately returns OK after the command syntax is verified, therefore the unsolicited
response +WIPERROR is needed to indicate any error conditions when the socket can not
connect to the peer, or when the socket loses connection to the peer.
The +WIPERR command is used query the last error that occurred within the socket subsystem.
