$JASC,msg,r[,PORTy]<CR><LF>
Where ‘msg’ is the name of the data message and ‘r’ is the message rate, as shown in
the table below. Sending the command without the optional [,PORTy] data field (without
the square brackets) will enact a change on the current port.
A message is turned off by sending a command with a zero value for the ‘r’ field.

Time and Date
When the ‘,PORTy’ data field is specified (without the square brackets and where ‘y’ is
A, B or C), this command will enact a change in the $GPmsg message on the Bluetooth,
Serial or USB port.
The SXBlue II GPS will reply with the following response:
$>
4.3.2 $JAGE
This command allows you to choose the maximum allowable age for correction data.
The default setting for the SXBlue II GPS is 3600 seconds for forestry applications;
however, you may change this value as you feel appropriate.
Using COAST technology, the SXBlue II GPS is able to use old correction data for
extended periods of time. If you choose to use a maximum correction age older than
1800 seconds for sub-60cm work, we recommend that you consider testing the receiver
to ensure that the new setting meets your requirements as accuracy will slowly drift with
increasing time.
This command has the following structure:
$JAGE,age<CR><LF>
Where maximum differential age timeout variable, ‘age’, may be a value from 6 to 8100
seconds.
