Hello! I cant close socket client be command AT+S.SOCKC - “ERROR: Pending data” 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 data” is raised. . I cant find description AT+S.READ. How can I do that properly?
ERROR: Command not found
ERROR: Pending data
