Please note that the working modes changed by the 0x03, 0x04 and 0x05 commands will not be written into

nonvolatile memory so the working mode will be restored to the former mode before change after power-off. If

needing to keep the changed mode after next power-on, users should use the write command instead to change

the parameters with these commands.

The data below is the response of Read command from the module with firmware < 2.0 so the

length byte is 0x0C---12bytes without breath period parameter.
