// with these changes, no one (not even OP board makers) should ever need u-center (the complex UBlox configuration program)
// no booting of Revo should be required during any setup or testing, just Send the settings you want to play with
// 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)

// End User Documentation
// There are two baud rates of interest
// The baud rate the GPS is talking at
// The baud rate Revo is talking at
// These two must match for the GPS to work
// You only have direct control of the Revo baud rate
// The two baud rates must be the same for the Revo to send a command to the GPS
// to tell the GPS to change it's baud rate
// So you start out by changing Revo's baud rate to match the GPS's
// and then enable UbxAutoConfig to tell Revo to change the GPS baud every time, just before it changes the Revo baud
// That is the basis of these instructions
// There are microprocessors and they each have internal settings
// Revo
// GPS
// and each of these settings can be temporary or permanent
// To change a Revo setting
// Use the System tab in the GCS for all the following
// Example: in Settings->GPSSettings click on the VALUE for UbxAutoConfig and change it to Disabled
// Click on UbxAutoConfig itself and the line will turn green and blue
// To change this setting permanently, press the red up arrow (Save) at the top of the screen
// Permanently means that it uses this setting, even if you reboot Revo, e.g. power off and on
// To change this setting temporarily, press the green up arrow (Send) at the top of the screen
// Temporarily means that it overrides the permanent setting, but it goes back to the permanent setting when you reboot Revo, e.g. power off and on
// To change an internal GPS setting you use the OP GCS System tab to tell Revo to make the GPS changes
// This only works correctly after you have matching baud rates so Revo and GPS can talk together
// "Settings->GPSSettings->UbxAutoConfig = Configure" sets the internal GPS setting temporarily
// "Settings->GPSSettings->UbxAutoConfig = ConfigureAndStore" sets the internal GPS setting permanently
// You want to wind up with a set of permanent settings that work together
// There are two different sets of permanent settings that work together
// GPS at 9600 baud and factory defaults
// Revo configured to start out at 9600 baud, but then completely configure the GPS and switch both to 57600 baud
// (takes 6 seconds at boot up while you are waiting for it to acquire satellites anyway)
// This is the preferred way so that if we change the settings in the future, the new release will automatically use the correct settings
// GPS at 57600 baud with all the settings for the current release stored in the GPS
// Revo configured to disable UbxAutoConfig since all the GPS settings are permanently stored correctly
// May require reconfiguring in a future release
// Changable settings of interest
// AutoConfig mode
// Settings->GPSSettings->UbxAutoConfig (Disabled, Configure, ConfigureAndStore, default=Configure)
// Disabled means that changes to the GPS baud setting only affect the Revo port
// It doesn't try to change the GPS's internal baud rate setting
// Configure means change the GPS's internal baud setting temporarily (GPS settings revert to the permanent values when GPS is powered off/on)
// ConfigureAndStore means change the GPS's internal baud setting permanently (even after the GPS is powered off/on)
// GPS baud rate
// Settings->HwSettings->GPSSpeed
// If the baud rates are the same and an AutoConfig mode is enabled this will change both the GPS baud rate and the Revo baud rate
// If the baud rates are not the same and an AutoConfig mode is enabled it will fail
// If AutoConfig mode is disabled this will only change the Revo baud rate
// View only settings of interest
// Detected GPS type
// Data Objects -> GPSPositionSensor -> SensorType (Unknown, NMEA, UBX, UBX7, UBX8)
// When it says something other than Unknown, the GPS and Revo baud rates are synced and talking
// Real time progress of the GPS detection process
// Data Objects -> GPSPositionSensor -> AutoConfigStatus (DISABLED, RUNNING, DONE, ERROR)
// Syncing the baud rates means that the GPS's internal baud rate setting is the same as the Revo port setting
// This is necessary for the GPS to work with Revo
// To sync to and find out an unknown GPS baud rate (or sync to and use a known GPS baud rate)
// Temporarily change the AutoConfig mode to Disabled
// Temporarily change the GPS baud rate to a value you think it might be (or go up the list)
// See if that baud rate is correct (Data Objects->GPSPositionSensor->SensorType will be something besides Unknown)
// Repeat, changing the GPS baud rate, until found
// Some very important facts:
// For 9600 baud or lower, the autoconfig will configure it to factory default settings
// For 19200 baud or higher, the autoconfig will configure it to OP required settings
// If autoconfig is enabled permanently in Revo, it will assume that the GPS is configured to power up at 9600 baud
// 57600 baud is recommended for the current release
// That can be achieved either by
// autoconfiging the GPS from a permanent 9600 baud (and factory settings) to a temporary 57600 (with OP settings) on each power up
// or by configuring the GPS with a permanent 57600 (with OP settings) and then permanently disabling autoconfig
// Some previous releases used 38400 and had some other settings differences
// The user should either:
// Permanently configure their GPS to 9600 baud factory settings and tell the Revo configuration to load volatile settings at each startup by:
// (Recommended method because new versions could require new settings and this handles future changes automatically)
// Syncing the baud rates
// Setting it to autoconfig.nostore and waiting for it to complete
// Setting HwSettings.GPSSpeed to 9600 and waiting for it to complete
// Setting it to autoconfig.store and waiting for it to complete (this tells the GPS to store the 9600 permanently)
// Permanently setting it to autoconfig.nostore and waiting for it to complete
// Permanently setting HwSettings.GPSSpeed to 57600 and waiting for it to complete
// Permanently configure their GPS to 57600 baud, including OpenPilot settings and telling the Revo configuration to just set the baud to 57600 at each startup by:
// (Less recommended method because new versions could require new settings so you would have to do this again)
// Syncing the baud rates
// Setting it to autoconfig.nostore and waiting for it to complete
// Permanently setting HwSettings.GPSSpeed to 57600 and waiting for it to complete
// Setting it to autoconfig.store
// Permanently setting it to autoconfig.disabled
// The algorithm is:
// If autoconfig is enabled at all
// It will assume that the GPS boot up baud rate is 9600 and the user wants that changed to HwSettings.GPSSpeed
// and that change can be either volatile (must be done each boot up) or non-volatile (stored in GPS's non-volatile settings storage)
// according to whether CONFIGURE is used or CONFIGUREANDSTORE is used
// The only user who should need CONFIGUREANDSTORE stored permanently in Revo is Dave, who configures many OP GPS's before shipping
// plug a factory default GPS in to a Revo, power up, wait for it to configure and permanently store in the GPS, power down, ship
// If autoconfig is not enabled
// it will use HwSettings.GPSSpeed for the baud rate and not do any configuration changes
// If GPSSettings.UbxAutoConfig == GPSSETTINGS_UBXAUTOCONFIG_CONFIGUREANDSTORE it will
// 1 Reset the permanent configuration back to factory default
// 2 Disable NEMA message settings
// 3 Add some volatile UBX settings to the copies of the non-volatile ones that are currently running
// 4 Save the current volatile settings to non-volatile storage
// If GPSSettings.UbxAutoConfig == GPSSETTINGS_UBXAUTOCONFIG_CONFIGURE it will
// 2 Disable NEMA message settings
// 3 Add some volatile UBX settings to the copies of the non-volatile ones that are currently running
// If the requested baud rate is 9600 or less it skips the step (3) of adding some volatile UBX settings
// Talking points to point out:
// U-center is no longer needed for any use case with this code
// 9600 is factory default for GPS's
// Some GPS can't even permanently store settings and must start at 9600 baud?
// I have a GPS that sometimes looses settings and reverts to 9600 and this is a fix for that too :)
// This code handles a GPS configured either way (9600 with factory default settings or e.g. 57600 with OP settings)
// Autoconfig.nostore at each boot for 9600, autoconfig.disabled for the 57600 with OP settings (or custom settings and baud)
// This code can permanently configure a GPS to be e.g. 9600 with factory default settings or 57600 with OP settings
// GPS's with 9600 baud and factory default settings would be a good default for future OP releases
// Changing the GPS internal settings multiple times in the future is handled automatically
// This code is written to do a configure from 9600 to 57600
// (actually 9600 to whatever is stored in HwSettings.GPSSpeed)
// if autoconfig is enabled at boot up
// When autoconfiging to 9600 baud or lower, the autoconfig will configure it to factory default settings, not OP settings
// That is because 9600 baud drops many of the OP messages and because 9600 baud is factory default
// For 19200 baud or higher, the autoconfig will configure it to OP required settings
// If autoconfig is enabled permanently in Revo, it will assume that the GPS is configured to power up at 9600 baud
// This is good for factory default GPS's
// This is good in case we change some settings in a future release
