Hello! I cant close socket client be command AT+S.SOCKC -  “ERROR: Pending dataâ€� is raised'.  According to UM1695 it should be flushing pending data  (using the AT+S.READ command) is mandatory before closing the socket connection (AT+S.SOCKC). If the buffer is not erased, the “ERROR: Pending dataâ€� is raised. . I cant find description 

AT+S.READ. How can I do that properly?

AT+S.READ

ERROR: Command not found

AT+S.SOCKC=00

ERROR: Pending data

    AT+S.SOCKQ returns the number of bytes of data waiting on socket specified by socket ID argument.

    In your case:

    AT+S.SOCKQ=00

    DATALEN: xxx

    There is a typo in the UM, any occurrence of AT+S.READ must be substituted with AT+S.SOCKR
