* Refactor GPSPowerState enum
Identifies a case where the GPS hardware is awake, but an update is not yet desired
* Change terminology
* Clear old lock-time prediction on triple press
* Use exponential smoothing to predict lock time
* Rename averageLockTime to predictedLockTime
* Attempt: Send PMREQ with duration 0 on MCU deep-sleep
* Attempt 2: Send PMREQ with duration 0 on MCU deep-sleep
* Revert "Attempt 2: Send PMREQ with duration 0 on MCU deep-sleep"
This reverts commit 8b697cd2a4.
* Revert "Attempt: Send PMREQ with duration 0 on MCU deep-sleep"
This reverts commit 9d29ec7603.
* Remove unused notifyGPSSleep Observable
Handled with notifyDeepSleep, and enable() / disable()
* WIP: simplify GPS power management
An initial attempt only.
* Honor #3e9e0fd
* No-op when moving between GPS_IDLE and GPS_ACTIVE
* Ensure U-blox GPS is awake to receive indefinite sleep command
* Longer pause when waking U-blox to send sleep command
* Actually implement soft and hard sleep..
* Dynamically estimate the threshold for GPS_HARDSLEEP
* Fallback to GPS_HARDSLEEP, if GPS_SOFTSLEEP unsupported
* Move "excessive search time" behavior to scheduler class
* Minor logging adjustments
* Promote log to warning
* Gratuitous buffer clearing on boot
* Fix inverted standby pin logic
Specifically the standby pin for L76B, L76K and clones
Discovered during T-Echo testing: totally broken function, probe method failing.
* Remove redundant pin init
Now handled by setPowerState
* Replace max() with if statements
Avoid those platform specific implementations..
* Trunk formatting
New round of settings.json changes keep catching me out, have to remember to re-enable my "clang-format" for windows workaround.
* Remove some asserts from setPowerState
Original aim was to prevent sending a 0 second PMREQ to U-blox hardware as part of a timed sleep (GPS_HARDSLEEP, GPS_SOFTSLEEP). I'm not sure this is super important, and it feels tidier to just allow the 0 second sleeptime here, rather than fudge the sleeptime further up.
* Fix an error determining whether GPS_SOFTSLEEP is supported
* Clarify a log entry
* Set PIN_STANDBY for MCU deep-sleep
Required to reach TTGO's advertised 0.25mA sleep current for T-Echo. Without this change: ~6mA.
