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.
