We are publishing this competition Firmware on an agreement with F5J League in Madrid to commence utilising this device as AMRT in the upcoming contests resuming the league after the pandemic break.
This will allow user to familiarise with the Firmware update technique which can be done from your mobile phone.
This firmware corresponds to the requirements for Second Class Competitions where emergency restart is allowed and has been submitted to FAI and hopefully in the next days will receive a homologation letter.
Emergency restart ON/OFF is the only competition setting that can be changed in this firmware.
Emergency throttle control is given to the pilot by the AMRT after 30 seconds of F5J “start height” calculation. Throttle lever or switch must be, as well, retracted back to below 1200 uuseconds pulse width to be rearmed (this voids the risk of a pilot forgetting the throttle at max power and the AMRT shutting the ESC and then receive a slam of power after these 30 seconds) and even allowing a perfectly valid flight in this, mistaken, condition.
If throttle is rearmed and used by the pilot, then the display in the OLED screen will turn into “—.-m” indicating an invalid F5J “start height” calculation and the flight will score a Zero
We need as well to update UI (User Interface) to allow the new syntax for competition files be used in updates.
We envisage, once in UI_1.21, you will keep a copy of both Firmware files available in a folder of your mobile and jump between FAI_S and STD firmwares using System conf. /Firmware Update to go back and forth during your training sessions.
In this menu, after version 1.20 inclusive you can store 2 Wi_Fi names (SSID) and their corresponding password.
Then you can Set your mobile Wi-Fi name in the first position and in second place your Home´s. This will make your life easier by not having to decide to change either of these to match a single one as in previous versions.
You can as well modify the time after entering Wi-Fi mode GliderKeeper will be trying to connect to those stored host Wi-Fi´s to be in STA mode in these LAN´s, before becoming a Wi_Fi AP (Access Point) by itself.
If you are intending to use GliderKeeper in AP mode, then you may decide to set this time to 5 seconds… for faster generation of the AP mode. If you intend to use the host Wi-Fis then our recommendation is to leave it in the range of 15-20 seconds, this will depend very much in your own LAN requirements. Maximum time has been set to 30 seconds.
Many people has asked why they cannot change their AP mode Wi-Fi name to a name like “John´s GliderKeepe”r, the reason is this ID and name is supposed to be used in future versions where we will be able to send the results to the Organisation in a competition and this ID will be used to make sure the correct GliderKeeper is sending the results.
If you set to just five seconds then it is possible it will not engage or will need many attempts. See the example:
One of the most useful things that GlikerKeeper features is you can access the configuration menus wirelessly in the airfield.
When training, many times you have to train your eye for a target altitude.
Say.. I want to cut at 60m this morning. And you want your altimeter advise you by cutting himself when at 60m.
With a normal altimeter this is possible but you need to have a Laptop available…
With GliderKeeper, go to Wi-Fi mode (maintain “nosedown” for 3 seconds after landing and connect with your mobile…) and tap the menu icon.
Then select Keeper Conf.
You will access to this screen:
There you can change the settings for your motor ON segment in matter of seconds change for instance to Altitude Shut and change this shutting altitude to 60.
Press “Save” and cycle the battery power.
In your next flight the motor will stop as soon as you reach 60 m high.
Then you can choose to go 5 m lower and very easy you can repeat these setting change.
Or do it with your time target.
The good thing is you can experiment with all these settings in the same training session very easily.
You can as well compare the actual F5J height readings from your OLED screen or in your terminal screen.
GliderKeeper will always measure F5J height (the max altitude during motor and the next ten seconds after throttle shut) despite any of those settings. We will be talking about the differences in the target altitude and the actual F5J height achieved in another post of the blog.
