The timing of this is poor, but I figured people might want to try an alternative to the quickly developing Andropilot.  I'd like to release what I have been working on, just to get feedback and bug reports.

The development of Copter-GCS stalled quite some time ago, but I recently picked up the source and started fixing bugs and adding features.  The app still has some quirks, and the UI is pretty terrible, but the function is there:

It includes:

-A full Heads Up Display

-Mission planning, with all commands and parameters available

-Follow-Me with offset mode, Guided Mode flight

-a Command Line terminal

-built for Android 2.2 and up

-full parameter editing

-works for Arduplane and Arducopter

-text to speach announces mode changes and waypoints reached

 

The included mission planner needs some instructions for use. All possible options are available, so it may be a bit dangerous if you don't use them correctly.

 

-to set a waypoint, long press in the map view, or use the "add waypoint" button in the list view menu.

-waypoint 0 is the uav's home location. It is important to keep the elevation frame as "Mav_frame_global" this means you are using actual ground elevation

-this app will automatically set the ground elevation (from Google's API) which is why it may pause for a few seconds when the first waypoint is added.

-when you add additional waypoints, the default frame is "mav_frame_global_relative_alt", which is an altitude relative to the home elevation, which is 75 meters by default.

-you can add as many waypoints as you like, then go to the list view to edit them, change then to do_jump or whatever, add in the parameters, etc. Then go back to the map and Save to UAV. I would suggest after you get confirmation, you Load from UAV to check that everyhting is correct

-All mission commands available to Mavlink have been included in this app, but there are some options that have not been implemented by Ardupilot or Arducopter.  Not all waypoint types will work, for example, DO_SET_RELAY doesn't work for APM2 UAVs.

 

 

 

 

 

 

 

 

 

The app connects to your telemetry with a bluetooth to XBee/3DR radio bridge:

APM<-->XBee/3DR<------------------------->XBee/3DR<-->Bluetooth<----------->Android Phone/Tablet

The bridge consists of an XBee or 3DR radio, and a Bluetooth radio, connected by serial port. There are expensive solutions for this, but I have made a inexpensive bluetooth module that includes a power regulator, a bluetooth radio, and a plug for my xbee.  If anyone is interested, I can detail the build process, and/or offer a hardware kit (with the smd bluetooth chip already soldered). The good thing about this set up, as opposed to a usb link to the radio, is (obviously) it is wire-free, and it is possible to have a stationary antenna, and even add in antenna tracking, and it is easily switched to link with a bluetooth enabled laptop..

According to [Pieter], this [DealExtreme Link] ($8.20 w/ free shipping to USA) works almost out of the box.  Set it to 57000 baud by connecting it to your computer with an FDTI cable, RX to TX, TX to RX, power and ground.  Open your serial terminal (I use RealTerm) with 9600 baud. Make sure LED on module is blinking (DON'T pair it with anything yet) Type in transmit field AT+BAUD7 and hit send (UPPER case letters or it wont work). You should get a OK response indicating that it worked.  You'll have to power cycle the bluetooth before the change takes effect.  Then pair with your phone.

Connect to a XBee adapter like this:

Another connection option is to connect the bluetooth directly to the APM telemetry port.  Remember the bluetooth range is short, so you won't be able to control it in the air, but you can set missions and tune param while on the ground.  Instructions from Ioan:

Cheap Bluetooth serial module (CBSM):

CBSM VCC -> APM Telemetry VCC

CBSM GND -> APM Telemetry GND

CBSM TX -> APM Telemetry RX

CBSM RX -> APM Telemetry TX

and then the phone connects directly to the APM's bluetooth adapter: 

Phone <----> APM + Bluetooth

If anyone wants to test, please remember that it is still BETA software, so there are certainly bugs.  

PLEASE REPORT ANY BUGS YOU FIND!! 

Also, feel free to make suggestions and feature requests....

This community has been very helpful and supportive, so I feel bad requesting donations, but I have put lots of time into this application, and I'm sure Bart has as well.  If you want to buy me a beer (or a PX4), you can donate whatever you like here: PAYPAL

-auto rotation while in MAV_CMD list crashes app

 

Feature Suggestions:
-connect to xbee/3dr/APM2 over usb

-keep screen on (added)

Thank you.

- The download link does not work.

Sorry, I was fixing something so I took it down for a sec...it should work now.

This is great!

Can you please give me more details on what bluetooth board I can use? Can I use something like this? If not, I would love to see more details on the hardware solution you came up with. 

Thanks you!

It looks like that will work, but I'm not positive. The spec sheet says it uses 3.3v, which is compatible with xbee, but you would have to figure out how to change the baud rate to 57000. I used the roving network serial Bluetooth 2.0 chip Sparkfun link.

I've got some details on my Bluetooth bridge here, Buildlog, but be aware that your setup may be different depending on what Bluetooth module you use.  All you really need is a Bluetooth Serial module, that operates at 3.3 volts.  Attach the RX of the bluetooth to the TX of the XBee, and the bluetooth TX to RX of XBee.  Attach power and ground to both.  I use a spare 3c Lipo, and made a 3.3v power regulator circuit, which makes it easy to swap out in the field.  I might be persuaded to produce a kit for the bridge if people are interested.

So, if I understand right, your setup it's something like this:

phone bluetooth <----> bluetooth + 3DR radio <-------> 3DR radio + APM

right?

How hard would it be to take away the 3DR radio from the equation? I know, the range will be 30 feet or so, but something like:

phone bluetooth <------> bluetooth + APM would be so much better....

phone bluetooth <------> bluetooth + APM would work. You just have to attach a serial Bluetooth to the telemetry port on the apm, and remember to match the voltage output. The apm operates at 5v.

This works almost out of the box. You only need to change the baud rate with an USB<-->Serial cable using the command AT+BAUD7 in your favourite terminal program.

HiI am hopeful you will be able to clear a few things up for me if you have a minute

i have purchased the module your link shows.  Can i just ask you to clear up a few things to make sure my head is in the same place

 

once ive changed to correct baud rate

I need to add 4 pins to the UART0 holes on the apm2.5 + board

i then cable from apm2.5 board directly to the BT module crossing rx and tx,

bond with phones blue tooth and it should work.

 

Am I correct so far ?

 

do i need to modify the power to the BT module work on 5v ?

 

Thanks in advance and I look forward to your reply

What is a XBee/3DR radio bridge, can one buy it or do you have to build one? I have one of these: cable

You linked to a USB cable. You should use Andropilot if you want to attach a radio over USB. This app only works with Bluetooth.

There is no off-the-shelf Bluetooth to XBee bridge, so you need to make one.

Cool!  Could I add your great HUD code to Andropilot?  Is there a github site?

take it from GCS-copter as I did
