اصلا به میکروکنترلر نیازی نیست. فقط ساختار دستور ها رو رعایت کنین :
• Only one command (or unsolicited result code) per command line needs to
be expected.
• The HOST, by default, shall not echo the command characters.
• The HOST shall always transmit result codes using verbose format.
• The characters below shall be used for AT commands and result codes
formatting:
<cr> corresponds to the carriage return (0/13) as stated in [6]
<lf> corresponds to the line feed (0/10) as stated in [6]
• The format of an AT command from the HF to the AG shall be:
<AT command><cr><lf>
• The format of the OK code from the AG to the HF shall be:
<cr><lf>OK<cr><lf>
• The format of the generic ERROR code from the AG to the HF shall be:
<cr><lf>ERROR<cr><lf>
• The format of an unsolicited result code from the AG to the HF shall be:
<cr><lf><result code><cr><lf>
