flushing delays etc.
10.1.2.5.
WAKEUP
To wake up from sleep, the user should send any kind of NMEA message to UART0
port. The content of this message is disregarded by the system. After the wakeup from
sleep, the system is always started in auto mode just like if $PUNV, START, AUTO*52
command would be sent.
For distinctness sake the following command can be used:
$PUNV,WAKEUP*2C
10.1.2.6.
STOP
With STOP command the user can stop the navigation and erase different kind of data
at the same time.
$PUNV,STOP,
bitmask
*cc
bitmask
is a hexadecimal number (without ‘0x’ prefix) specifying the data to be erased.
It has the same set of possible values as for START command described in 10.1.2.3. The
exception is “Reset Configurations from FSH and RAM”, which should not be used with
STOP command.
There is a number of predefined mnemonics to be used with the STOP command. When
alias is used the command has the following form:
$PUNV,STOP,
alias
*cc
alias
is a mnemonic specifying the particular bitmask. It has the same set of possible
values as for START command described in 10.1.2.3. The only exceptions are FACTORY,
HOT and AUTO aliases, which are not supported for STOP command.
STOP command in its simplest form is also supported:
$PUNV,STOP*29
,which just stops navigation without erasing anything. So effectively it is equal to
$PUNV,STOP,0*35
