8.2.12 $JQUERY,GUIDE
This command is used to poll the SXBlue GPS for its opinion on whether or not it is
providing suitable accuracy after the both SBAS and GPS have been acquired (up to 5
min). This feature takes into consider the download status of the SBAS ionospheric map
and also the carrier phase smoothing of the unit.
This command has the following format:
$JQUERY,GUIDE<CR><LF>
If the SXBlue GPS is ready for use with navigation or positioning with optimum
performance, it will return the following message:
$>JQUERY,GUIDE,YES<CR><LF>
Otherwise, it will return the following message:
$>JQUERY,GUIDE,NO<CR><LF>
8.2.13 $JRESET
This command is used to reset the GPS engine inside the SXBlue GPS to its default
operating parameters.
This message has the following format:
$JRESET[,ALL] <CR><LF>
The ‘[,ALL]’ field is optional. When this command is issued without this field present, the
configuration only is defaulted. Please note that the default of the GPS engine does not
necessarily correspond with the factory setup of the SXBlue GPS.
When the ‘,ALL’ field is present (without the square brackets), the almanac is also
defaulted. Issuing this command with this optional data field is not usually necessary.
Caution – We do not recommend the issue of the $JRESET,ALL<CR><LF>
command under most circumstances as it will erase any feature subscriptions
from memory of the SXBlue GPS.
8.2.14 $JSAVE
Sending this command is required after making changes to the operating mode of the
SXBlue GPS receiver. It is possible, however, that after making changes to the
operating mode through the serial port, and later using the menu system, that the mode
becomes saved. This could occur as changes through the menu system automatically
invokes the $JSAVE command. However, do not rely on this feature to save your
changes.
This command has the following structure:
