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 baud rate (9600bps, 19200bps, 38400bps, 57600bps, and 115200bps), and the
module will automatically detect the baud rate. Before users power on the module again, it accomplishes UART
communications at the automatically detected baud rate. To change the original baud rate during
communication, set a new baud rate for the module on the MT. Then the MT will change its transmitting baud
rate.
If users send AT+IPR to the module to set the baud rate to a certain value, the module cannot automatically
detect a baud rate unless users 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 baud rate 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 fixed baud rate mode:
\r\nMODEM:STARTUP\r\n is output, indicating that the module is initialized.
\r\n+PBREADY\r\n is outpu, indicating that the phonebook is ready.
Boot log in automatic baud rate detection
The module will not output any boot log before an AT command is input because the baud rate is unknown.
\r\nMODEM:STARTUP\r\n is output if users enter AT/r before starting the module and
\r\n+PBREADY\r\n is output after the phonebook is ready.
Only \r\n+PBREADY\r\n is output after the phonebook is ready if users enter AT/r after starting the
module.
