+CMGF – Preferred Message Format
The formats implemented are the text mode and the PDU mode.
In PDU mode, a complete SMS Message including all header information is passed as a
binary string (in hexadecimal format, so only this set of characters is allowed:
{‘0’,’1’,’2’,’3’,’4’,’5’,’6’,’7’,’8’,’9’, ‘A’, ‘B’,’C’,’D’,’E’,’F’}).
Each pair or characters is converted to a byte (ex: ‘41’ is converted to the ASCII
character ‘A’, which ASCII code is 0x41 or 65).
In Text mode, every commands and responses are in ASCII characters.
The chosen format is stored in EEPROM by the command +CSAS.
