native rM2M_CfgRead(cfg, pos, data{}, size);
Reads a data block from the specified position in a configuration memory block. The function is also
informed which of the 10 available memory blocks in the internal flash memory should be read. Use the
"rM2M_Pack", "rM2M_GetPacked" or "rM2M_GetPackedB" functions to unpack the read data.
Parameter Explanation
cfg Number of the configuration memory block starting with 0 for the first memory
block. The device comprises 10 independent memory blocks.
pos Byte offset within the configuration memory block to determine the position from
which the data should be read
data Array to store the data to be read
size Number of bytes that should be read from the configuration memory block
Explanation
Return value
l
Size of the memory used in the configuration memory block
l
ERROR_MEM, if enough temporary memory (RAM) is not currently
available. (can occur if "RAM in a volatile manner" is selected as the type of
storage for several configuration memory blocks)
l
< OK, if another error occurs (see "Return codes for general purposes" in
chapter "Constants" on page 84).
native rM2M_CfgDelete(cfg);
Deletes all of the data of the transferred configuration memory block
Parameter Explanation
cfg Number of the configuration memory block starting with 0 for the first memory
block. The device comprises 10 independent memory blocks.
Explanation
