：
Full cold start command: $PGKC030,4,2*2A<CR><LF>Hot start command: $PGKC030,1,1*2C<CR><LF>
Remarks: Arg2 is set to 1 for both warm start and warm start, and Arg2 is 1, 2, and 3 for full cold start.
In general, the cold start is the full cold start mode, Arg1 is set to 4, Arg2 is set to 2, and the hardware boot mode is not used.
7.2.3 Erase auxiliary information
Command: 040
Erase auxiliary information in flashArguments: None
Example:
$PGKC040*2B<CR><LF>
7.2.4 Low power mode
Command: 051
Enter standby low power mode
Arguments:
Arg1: "0", stop mode
Example:
$PGKC051,0*37<CR><LF>
This command can be woken up by sending any command, invalid commands can also be used, the hardware can be woken up by plugging
and unplugging the serial port, and the original low-power command can be sent directly.
7.2.5 Message interval configuration
Command: 101
Configure the interval for outputting NMEA messages (unit: ms)
Arguments:
Arg1: 100-10000
Example:
$PGKC101,1000*02<CR><LF>
The command set is to output NMEA data every 1000ms, which is 1s.
Remarks: When setting the message interval output above 2HZ, first increase the baud rate to above 115200 to ensure high-frequency NMEA
message output. This command is not saved in Flash, and will be restored to the original NMEA output frequency after power failure; baud
rate Modification requires firmware version 3.0 or above to support configuration, and NMEA frequency does not support saving.
7.2.6 Periodic low power mode
Command: 105
Enter periodic low power mode
Arguments:
Arg1:
"0", normal operating mode
"1", period ultra-low power tracking mode
“4”, directly enter ultra-low power tracking mode
"8", low power consumption mode, you can wake up by sending commands through the serial port
Arg2:
Run time (ms), this parameter has effect in periodic mode with Arg1 = 1.
Arg3:
Sleep time (milliseconds), in periodic mode where Arg1 is 1, this parameter works.
Example:
$PGKC105,8*3F<CR><LF
$PGKC105,1,5000,8000*3B<CR><LF
Note: In low-power mode, the CPU will sleep and can be woken up through the serial port; in ultra-low-power tracking mode, when the CPU
is powered off, it will automatically wake up periodically for positioning output.
