Improve the performance of the parser by using a Bytebufffer.

Add usb joystick capabilities to the RC override function.

How about adding a text scale option in settings?

For smaller android devices this can be very helpful.

Add a View to change parameters of the board.

Add a set mode menu option, like the one on Mission Planner.

This way the waypoint manager can be acessed by any activity.

Fix the following error that happens when switching activity's while connected to a drone.

Add the option to share log and waypoints files via google drive and/or email.

Implement USB direct connectivity to FTDI chips.

There is a partial development on the branch USB 1c011cf

Maybe translating the app would be good. But is best to get the other issues done first.

I can translate it to PT-BR.

Add a flight track to the flightMap fragment.

Add some sort of guided (point and click) flight mode to the flightData Fragment.

Should work like mission planner.

Add a password protected user mode only for monitoring mavlink data, which has no permission to send data to the plane.

Improve the navigation of the app. Currently there is a backstack of the previus screens and to exit the app you have to pres back a lot of times. It would be better that pressing back always returns to the flight data screen, where your past doesn't matter.

Another press show something like "press again to close the app", and another closes the app.

Firstly the design seems to be designed towards arduplane only, it really needs support for copter, rover etc

And secondly i would like to offer to do the artwork for the UI, improve it.
I fly Actual aircraft being a plane called the grob vigilant so i could design it around that?
But more importantly you want a design that doesn't infringe on the mission planner software and is your design.

I love to do artwork and have lots i could make for you
So email me if interested on [email protected]

Suggestions as follows : icons for your model or optional pointer icon for more precision

connectButton is null because onCreateOptionsMenu being called after the notifyConnected() / notifyDisconnected()

Match HUD mode indicatior with FlightData menu spinner mode indicator.

Add a plot for in flight values, like altitude...

A test made on the field with a real plane should be made.

Kirill: Is it possible to control using inclination of table (by accelerometers)?

Currently on all the map fragments the markers are handled by their snippet text, probably a hashmap of the id's would be better.

Add number of visible GPS satellites to the HUD

List of thing to be improved:

• WPs can be re-arrange by sliding its position in the waypoint list
• Slide to remove
• Click to edit

Add a menu for editing waypoints when clicked, with the following items:

• WP type
• Height

Advanced options based on the WP type like :

• type limited to Loiter (for some time), lift-off (to a heigth), land, circles and RTH.
• speed to next WP

with mission planner, it logs a file for google earth to visualize the flight, at a later stage can this be implemented?

Give the option of sending RC commands, to eliminate the RC Tx/Rx on Ardupilot.

Add icons for Quadcopters, and the corresponding flight modes.

Drone heading in flight map and hud is different. Use hud heading for both since GPS heading can be very wrong in a quad.

Develop a simple manual on the Github Wiki.

Moving the plane on the flightDataFragment causes the heap to grow continusly, generating the following message:
Grow heap (frag case) ...
Until the heap explodes and the connection is lost.

The following itens must be added to the HUD. It's probably best to keep the same layout as MP.

• Add a RSSI (signal strengh)
• GPS fix and number of visible GPS satellites to the HUD
• Battery voltage
• Battery amperage
• Battery Capacity

Not everyone has Mavlink but they don't want to lug a laptop to the field to setup the ardumega, so if it is possible, could a USB link be implemented to allow direct connection to the board?

the display dims which in daylight can be a big issue

Add an FPV screen to show a FPV stream on screen

Use icons on the action bar to minimize the app footprint.

Craig Elder: Can I make a suggestion that you move the roll angle numbers above the arc and the tics below.

Find a better joysticck widget.

Make joystick work as a mode 2 rc radio. Witch means that the trottle stick should hold its position insted of returning to center.

Add the option to work as a mode 1 controller.

Copyed from Andropilot

Add a Pids adjust menu so that people can adjust the PIDs in the app, that would be very useful.

Just the basic pids lice the Flight modes, channel 7 function and pich/roll rates.

Offline maps access. There is some code already implemented see GCSActivity.

I've noticed that the application hangs on when tablet orientation changes. Sometimes it completely hangs on, sometimes I need to press "Connect" again. But all the time when orientation is changed it looses connection.
I have Archos 101g9 tablet, Android 4.1

Like the one from Andropilot

Currently some when changing the settings can cause the App to crash.

For example changing track-length during fligth.

Add voice notification for events, such as:

• Armed / Disarmed
• Low battery voltage / charge (The battery discharge function already does a great job at this)
• Weak radio signal, signal loss
• GPS signal loss
• Flight mode changed
• Waypoint reached
• Next target (waypoint number or home)

And periodic notifications, such as:

• Flight Time - for every 10 min. of flight
• Battery discharge notification - every 10%
• Altitude - periodically
• speed (air or ground dependent on the sensors) - periodically

Make the logging files compatible with Mission Planner .tlog files.

A TTS class has been implemented, but it's use is minimal.

Add more uses for this class, and possible a configuration menu.

Add a class to prefetch a map tile database to the local storage, for use as offline maps.

Add battery information to the HUD fragment.

Fragments should be implemented to have multiview screens like HUD and flight data in on screen. When rotating the screen fragments must rearrange.

Implement basic commands trough voice recognition, commands like:

• Change flight mode
• Set current Waypoint
• Query drone status ( remaining battery, altitude, flight speed)

Mavlink stream rates should be handled in a better, more complete way.
