HOW TO PROCEED
-Delete all data files (save them first if desired).
-First update to FAI_S or FAI_F fw.
-Then update UI to x.30 (mandatory)
-Finally, update to the desired final Fw if it was not already on board.

Changes Fw x.30 vs x.29 
2/Apr/25
Corrects flight time calculation error if barometric pressure (QFE) <1023.25 hPa.
It is necessary to change UI x.30.

Changes in GliderKeeper Fw 1.29 vs 1.26
19/Feb/25
- All improvements from version 3.29 (see below) plus the following features already available in PICO:

- Improved Throttle Reading Technique, less noise in the throttle signal.
- Double recording time: 10 hours or 255 flights, PICO is 5 hours or 255 flights.
- New LED flashing strategy, showing the flight sequence. 

One green flash: Recording.
Two green flashes: Engine phase. F5J. Altitude is being calculated.
Three green flashes: Gliding phase.
No green flashes: Landed. Flight time has been calculated.

Solid blue: Searching for WiFi access point.
One blue flash: AP mode (your IP is 192.168.4.1).
Two blue flashes: STA mode (IP provided by the access point).
Three blue flashes: less than 25% memory remaining
Five blue flashes: Emergency use or memory overflow
Intermittent blue flashes: Vertical, waiting 3 seconds to enter WiFi mode: (solid blue).

POWER-UP SEQUENCE
- Shorter time for throttle arming. (By performing multiple tasks in parallel).
- GliderKeeper now arms by default on the throttle when turned on. (It was reported that in some cases, moving Gliderkeeper during the first few seconds could cause it to enter Wi-Fi mode).
- GliderKeeper now needs to be in an upright position, and remain upright, for 3 seconds to enter Wi-Fi mode. This status is now indicated by a flashing blue LED.
- Otherwise, it will return to the default throttle arming condition.
- More robust memory management. (To reduce the risk of memory corruption due to power outages in the power-up sequence).
- Improved signalling of successful throttle arming.
– The green LED flashes ‘longer’ to indicate that it has been armed correctly. (It will dim to indicate that it is recording).
– Improved behaviour in case of signal loss (broken cable).

TIP: RADIO MASTER EQUIPMENT ARMING TIME
Some Radio Master users have reported that their systems take several seconds to start generating control signals and fall into GliderKeeper's security/Wi-Fi arming.
GliderKeeper has a personal safety feature that would lock the throttle if the throttle signal is not present after a few seconds.
If you find yourself in this ‘input error’ condition, you can enter Wi-Fi mode.
- Go to System Settings/Wi-Fi Settings and change:
- ‘Time to connect to host Wi-Fi’
If 11 seconds will give you 8 seconds before the ‘input error’ is triggered
If it is 13 seconds, you will have 12 seconds before the ‘input error’ is triggered.
– The functionality of this parameter for connecting to Wi-Fi is the same as before.
GliderKeeper strongly recommends using a backup power system in this case,
as battery failures are relatively common in F5J installations.
– Remember that losing control of your model for a few seconds,
especially at low altitude, can be dangerous for property
and people. 
– Fly in these circumstances at your own risk.

IMPROVEMENTS IN FLIGHT TIME CALCULATION
– Improved reliability by adjusting the altitude window for recording events in light of accumulated experience.
– Landing detection has been improved to reduce the chances of a “false positive” (landing too early) or “false negative” (landing not detected or detected too late).
- The secondary landing detection system has been improved: it will activate automatically after 25 seconds on the ground or can be activated by going into Wi-Fi mode (as before, like a switch to tell the aircraft that we are on the ground).
- The landing algorithm has been designed to suit most F5J competition landing profiles. It includes a ‘touch and go’.
- However, landings that are too hard (high-speed approaches) or too soft (i.e., landing in tall grass without the fuselage touching the ground) may require human verification of the landing graph.
- In any case, this new algorithm has been designed to not give more flight time to these marginal landings than in the case of human timing.

WI-FI MODE
- Drastic improvement in stability and speed in AP mode.
- A label will advise you to set the STA mode.
- Click on the label to get a summary of the manual.
- Type [myIP]/manual.pdf in your browser to access this summary of the manual, integrated into the GliderKeeper memory.
– However, it is very important to maintain a good radio link: 
--keep the R/C transmitter turned off, several metres away
--and/or an excellent line of sight between AP and STA

USER INTERFACE FILES
– Improved data download, now downloads all available data and not just the part of the memory that has been overwritten in the event of memory overload.
– Keeper configuration: STD Fw, now a single switch for selecting and configuring Time and Altitude Shut.
– Track list: Displays a more readable pyjama table.
– The last flight is displayed at the top, making it more usable.
– The pyjama list is compatible with the F5K display.
– Prevents the graph list from appearing until all data has been loaded (fixed issue where in some cases it appeared that only the last flight could be plotted).
– Graph: a counter now shows the download size, useful for checking a stuck connection; if this counter freezes for a few seconds, try again after restarting the unit.
