// with autoconfig enabled, just change the baud rate in HwSettings and it will change the GPS internal baud and then the Revo port
// with autoconfig disabled, it will only change the Revo port, so you can try to find the current GPS baud rate if you don't know it
// GPSPositionSensor.SensorType and .UbxAutoConfigStatus now give correct values at all times, so use .SensorType to prove it is
// connected, even to an incorrectly configured (e.g. factory default) GPS
// Use cases:
// - the user can plug in a default GPS, use autoconfig-store once and then always use autoconfig-disabled
// - the user can plug in a default GPS that can't store settings (defaults to 9600 baud) and always use autoconfig-nostore
// - - this is one reason for coding this: cheap eBay GPS's that loose their settings sometimes
// - the user can plug in a default GPS that _can_ store settings and always use autoconfig-nostore with that too
// - - if settings change in newer releases of OP, this will make sure to use the correct settings with whatever code you are running
// - the user can plug in a correctly configured GPS and use autoconfig-disabled
// - the user can recover an old or incorrectly configured GPS (internal GPS baud rate or other GPS settings wrong)
// - - disable UBX GPS autoconfig
// - - set HwSettings GPS baud rate to the current GPS internal baud rate to get it to connect at current (especially non-9600) baud rate
// - - - you can tell the baud rate is correct when GPSPositionSensor.SensorType is known (not "Unknown") (e.g. UBX6)
// - - - the SensorType and AutoConfigStatus may fail at 9600 and will fail at 4800 or lower if the GPS is configured to send OP data
// - - - (way more than default) at 4800 baud or slower
// - - enable autoconfig-nostore GPSSettings to set correct messages and enable further magic baud rate settings
// - - change the baud rate to what you want in HwSettings (it will change the baud rate in the GPS and then in the Revo port)
// - - wait for the baud rate change to complete, GPSPositionSensor.AutoConfigStatus will say "DONE"
// - - enable autoconfig-store and it will save the new baud rate and the correct message configuration
// - - wait for the store to complete, GPSPositionSensor.AutoConfigStatus will say "DONE"
// - - for the new baud rate, the user should either choose 9600 for use with autoconfig-nostore or can choose 57600 for use with autoconfig-disabled
// - the user (Dave :)) can configure a whole bunch of default GPS's with no intervention by using autoconfig-store as a saved Revo setting
// - - just plug the default (9600 baud) GPS in to an unpowered Revo, power the Revo/GPS through the servo connector, wait some time, unplug
// - - or with this code, OP could and even should just ship GPS's with default settings
// if we add an "initial baud rate" instead of assuming 9600 at boot up for autoconfig-nostore/store
// - the user can use the same GPS with both an older release of OP (e.g. GPS settings at 38400) and the current release (autoconfig-nostore)
// - the 57600 could be fixed instead of the 9600 as part of autoconfig-store/nostore and the HwSettings.GPSSpeed be the initial baud rate?
// About using UBlox GPS's with default settings (9600 baud and NEMA data):
// - the default uBlox settings (different than OP settings) are NEMA and 9600 baud
// - - and that is OK and you use autoconfig-nostore
// - - I personally feel that this is the best way to set it up because if OP dev changes GPS settings,
// - - you get them automatically changed to match whatever version of OP code you are running
// - - but 9600 is only OK for this autoconfig startup
// - by my testing, the 9600 initial to 57600 final baud startup takes:
// - - 0:10 if the GPS has been configured to send OP data at 9600
// - - 0:06 if the GPS has default data settings (NEMA) at 9600
// - - reminder that even 0:10 isn't that bad. You need to wait for the GPS to acquire satellites,
// Some things you want to think about if you want to play around with this:
// - don't play with low baud rates, with OP data settings (lots of data) it can take a long time to auto-configure
// - - at 2400 it could take a long time to autoconfig or error out
// - - at 9600 or lower the autoconfig is skipped and only the baud rate is changed
// - if you autoconfigure an OP configuration at 9600 baud or lower
// - - it will actually make a factory default configuration (not an OP configuration) at that baud rate
// - remember that there are two baud rates (inside the GPS and the Revo port) and you can get them out of sync
// - - rebooting the Revo from the Ground Control Station (without powering the GPS down too)
// - - can leave the baud rates out of sync if you are using autoconfig
// - - just power off and on both the Revo and the GPS
// - my OP GPS #2 will NOT save 115200 baud or higher, but it will use all bauds, even 230400
// - - so you could use autoconfig.nostore with this high baud rate, but not autoconfig.store (once) followed by autoconfig.disabled
// - - I haven't tested other GPS's in regard to this
// since 9600 baud and lower are not usable, and are best left at NEMA, I could have coded it to do a factory reset
// - if set to 9600 baud (or lower)
