Remora Firmware Release Notes

As new versions of firmware are released, the release notes will be updated below.


- Fixed low voltage behaviour for older devices


- Added an AutoAPN entry.


- Improved low battery voltage behaviour

- Completed third party server support
- Added geofence functionality

- Updates to gsm

- Added SMS support for resetting the external server (#*,DSERVER)

- External server support

- More flexible tamper detect settings (can now disable to save power)


 - Fix for EMU_110 errata, which caused occasional reboots during wake up on a very small number of devices.

- When GSM debugging set to INFO, and MultiAPN specified, log network MCC MNC in RSSI message.
- When Control debugging set to INFO, log time to successful network registration.
- If GPS wander suppression is active, and device has not moved, previous fix is logged with an updated time.
- Expose recovery mode parameters.

- To aid production testing, version info is sent out the debug serial port on startup: Product ID, Hardware Revision, Firmware Major and Firmware Minor

- Parameterised upload timeouts/retry limits: time to network registration; complete session time; retry limit.
- Updated device stats message log reason.
- New AutoAPN entries.
- Recovery mode timeout option.

- Fixed wakeup loop if HES board fitted and batteries inserted outside of GPS and GSM coverage
- Disabled SIM detection switch, for robustness
- Added detection of clock and flash startup issues

- Updated Aeris AutoAPN entry
- Added new device stats message. Added max temperature and initial battery voltage stats.
- UE910 12.00.428 lower case 'at' handling

- Added new AutoAPN entries for US

- Unused LFRCO disabled in main firmware for a neglible power saving
- Power saving fix - idle core during accelerometer debounce
- Improved i2c error handling

- Changed GPS wander filter range and defaulted to off
- Fixed bug in jostle tracking mode. ~1mA battery drain in-trip if logging was increased from the default.
- Increased maximum accelerometer threshold from 3x63mG to 8x63mG, improved error resilience

- Fixed heartbeat timing bug that could extend the heartbeat period by up to 100%
- Sped up changes to and from AutoAPN
- Added RTC polls to the accelerometer wake count in gps tracking mode
- Updated to EFM32 pack 1.4

- Added distance filtering to Upload On Jostle
- Removed Upload On Jostle support from Periodic Only tracking mode
- Added accelerometer wakeup trace for debugging

- Reduced software jostle sensitivity, linked to hardware sensitivity parameters and exposed
- AutoAPN validation fix
