Problem simulating a location

[panagiotis merakos]

Hello Graham,

I have done a couple of tweaks to your code, and I can now successfully
read the location data from the simulator.

First thing - it is not suggested to call all these 3 commands/functions in
one go:

mobileStartTrackingSensor
mobileSensorReading()
mobileStopTrackingSensor

as the "mobileStartTrackingSensor" command takes some time for the sensors
to start tracking. So a good place to add this would be on openCard, or in
a separate button.

Similarly, I have removed the "mobileStopTrackingSensor" from the button
script, and have put it on the closeCard handler (you can but it in a
separate button for your testing if you wish)

So the main button code becomes:

On mouseUp
   put "now trying to get a one-off location reading" & return after fld
"TheReport"
   put mobileSensorReading("location",true) into tSensorData -- this
returns a string with the current latitude, longitude and altitude
   if tSensorData is empty then
      put "no location info!!" & return after fld "TheReport"
   else
      put tSensorData & return after fld "TheReport"
   end if
end mouseUp

However, it seems there is a bug in the function
mobileSensorReading("location",false)

which will be fixed asap

You can workaround this bug by using the "detailed" form of this function,
i.e. mobileSensorReading("location",true)

Note that the "detailed" form returns an array instead of a comma separated
list, so you have to modify the script as follows:

On mouseUp
   put "now trying to get a one-off location reading" & return after fld
"TheReport"
   put mobileSensorReading("location",true) into tSensorData -- this
returns a string with the current latitude, longitude and altitude
   if tSensorData is empty then
      put "no location info!!" & return after fld "TheReport"
   else
      combine tSensorData using return and ":"
      put tSensorData & return after fld "TheReport"
   end if
end mouseUp

Also, in the Simulator menubar, choose a location such as "City Run" or
"Freeway Drive" so as you could see the changes.

Hope this helps.

Kind regards,
Panos
