Neo_M590E V1 GPRS Module AT Command Set

Copyright © Neoway Technology Co., Ltd 1 Boot LOG Instruction The default baudrate of the module is in automatic detection. The mobile terminal (MT) sends AT\r in accordance with the standard baudrate (9600bps, 19200bps, 38400bps, 57600bps, and 115200bps), and the module will automatically detect the baudrate. Before your repower on the module, it accomplishes UART communications at the automatically detected baudrate. If you need to change the original baudrate during communication, you must set a new baudrate for the module on the MT. Then the MT will change its transmitting baudrate. If you send AT+IPR to the module to set the baudrate to a certain value, the module cannot automatically detect a baudrate unless you run the command AT+IPR=0\r. After the module is started, send AT\r to the UART1 of the module. The module returns AT characters, indicating that the baudrate matches successfully. Send AT\r to the UART again and the module will return OK. Then, the module is ready to execute AT commands. Boot log in automatic baudrate detection The module will not output any boot log before you enter an AT command because the baudrate is unknown.  \r\nMODEM:STARTUP\r\n is output if you enter AT/r before starting the module and \r\nMODEM:STARTUP\r\n is output after the phonebook is ready.  Only \r\n+PBREADY\r\n is output after the phonebook is ready if you enter AT/r after starting the module.

For example, China Unicom 8613010888500 should be 683108705505F0 here. 3>: 0100 01: Indicates basic parameters 00: indicates message baseline value 4>: Convert the receiving number into hexadecimal. For example, the number length is 11 bits and then the hexadecimal length should be 0B. 5>: 81 (Receiving mode) there are multiple receiving modes. 81 indicates that the receiving mode is unknown. 6>: Inversion of every two bits (add F if the bits are not sufficient) in the recipient number. For example, 13421839693 should be 3124819396F3 after conversion. 7>: 0008 8>: The hexadecimal length of the SMS message content. For example, the UCS2 code of hello is 00080A00680065006C006C006F, that is 10 bits and the hexadecimal length is 0A. 9>: Message content, for example, the USC2 code of hello is 00080A00680065006C006C006F. One PDU message contains the above 9 parts and the parameter values are determined by the actual situation. If the SMSC address length is 0, replace 08 with 00 and the SMSC type and address fields must be omitted. The following is an example of the PDU message whose SMSC address length is not 0: 0891683110808805F001000B813124819396F300080A00680065006C006C006F Wherein, 0891 683108705505F0: SMSC number of China Mobile 0100 0B: the length of the recipient number 81: Receiving mode 3124819396F3: The number of recipient 0008 0A: The length of the content 00680065006C006C006F: SMS message content Message content: hello The SMS message content starts from 0100, so the value of LENGTH in AT+CMGS=LENGTH is 23. The following is an example of the PDU message whose SMSC address length is 0:
