Firmware Changelog

Version 9.6

• scan SD card for FAT errors
• restart device if write to SD card failed
• 15 tries/retries on establish WIFI connection to AP/Base Station App
• improved WIFI communication protocol
• ignition log;

Version 9.7

• periodic events

Version 9.8 - 10.1

Internal release and beta tests

• Ignition log saved on gps file;
• Sleep mode;
• Longer events up to 1 min (max 15 seconds from existing buffer);
• GPRS module - send event type, ignition info and GPS string via GPRS using http;
• Serial communication - 2 ways protocol;

Bug Fixes

• "Phantom" frames
• Clips jumps
• 20 seconds delay on GPS tick fail to internal tick

Version 10.2

Public release

• Ignition log saved on gps file;
• Sleep mode;
• ability to config image resolution, 9 modes;
• speed & super speed trigger events;
• event header;
• Longer events up to 1 min (max 15 seconds from existing buffer);
• RTC correction and ignition log after valid GPS line - solve also RTC hardware oscillator issue

Bug Fixes

• "Phantom" frames
• Clips jumps
• 20 seconds delay on GPS tick fail to internal tick

Version 10.3

Public release

Bug Fixes

• trigger speed events on invalid gps line.

Version 10.4

Public release

• Blue wire event inhibited for 15 secs after ignition trigger.

Version 10.5

Internal release only

• Added support for MMA8451 accelerometer, configs and FIFO buffer data acquisition(300 values / sec)
• New event file format (version 2) to support g-forces values
• Calculate MAX g-force value during an event.
• Send off/on flag via socket for eth0 interface(off while is in event/sleep mode, on while is in transfer mode) - notice 50% decrease of wifi module current consumption while camera is not in transfer mode;
• Use socket mechanism to set up eth0 interface and get rid of "ifconfig" system call.
• Verify wifi module interface(eth0) presents after wake-up call (transfer mode will be passed if the interface is not present and go directly to sleep mode).
• Improve errors call to send camera restart on each thread mechanism.

Version 10.6

Public release

• WiFi protocol improvements - socket transfer buffers adjustments.
• Improve full SD card delete mechanism.
• Use no blocking send and 20 sec timeout in wifi files transfer protocol.

Bug fix

• Eliminate first socket close and object delete call on socket error that could cause a NULL pointer call;
• Add extra check on write to SD to eliminate missing bytes(related to CC 100% load transfer issue);
• Solve SW LED SD full, red blink after transfer and go back event mode.

Version 10.7

Public release

• Added new watch dog mechanism which is monitoring all main threads.
• WiFi Protocol extended - added SD format command.
• WiFi Protocol improvements - Disable wifi interface while transfer is in pending state.
• Added enable/disable accelerometer(LIS3LV02) axis capability; Config file (size.cfg) extended to support it.

Version 10.8

Public release

• WiFi Protocol extended - added accelerometer axis status command;
• added accelerometer axis status to event header (Aux info 1 - first 3 bits, 0 => forward, 1 => lateral, 2 => vertical )
