Single-chip microcomputer controls GPRS module to send short messages, seek procedures and add high scores!

Of course, GPRS module sends data to microcontroller through serial port, and the data format depends on GPRS modules of different manufacturers. So how does the single chip microcomputer read the short message of GPRS module? 1.GPRS module can be set by AT instruction, so thAT the GPRS module can immediately hand over the short message content to the microcontroller after receiving the short message, or it can be set by at instruction, and then the microcontroller sends at instruction to read the short message content from the GPRS module. 2. How to analyze short messages? First, connect the module to PC, use serial port software to check the format of SMS content, and then program and run AT. SMS character set can be selected from UCS2 or GSM. Some domestic old mobile phones do not support GSM character set, so it is recommended to analyze UCS2 character set! .
