no answer ? 

I have no XBee module. I buy the new kit 3DR Radio 433.
I want to use a tracking antenna.

I'm interested as well. I can hook a 3DR to a small form factor laptop but the ardustation would be a more portable and integrated solution.

Hello

Sorry, but my English is poor.
I added a 3DR-module in my Ardustation and it works well.

You must take the Rx and Tx ports of the XBee socket and 5V and Ground of the contacts under the buzzers.

The LEDs (Rx+Tx) are not driven

Fantastic ! Thank you very much Joachim. I will then buy an ardustation, it is very cheap and will be great on the field.

Joachim, YOU ROCK!  Thank you for figuring this out for the rest of us!  Quick question, this requires two sets of 3DR radios, one air and ground from my laptop to the aircraft, and the second set is used for the tracker with the ground 3DR in my laptop USB port and the air module plugged into the ardustation, is this correct?

Chad,

although I didn't build this yet, I think that it will be tricky. The 3DR radios are really point to point type, not mesh network like Xbee. You might then be right about the usage of two pairs of radios (on different network ids) to use both a ground station and a laptop but I would tend to think that you usually use either a ground station or a laptop with the ground station software. I think indeed that it will be very difficult to hook up two transceivers on the flight controller as it might be designed for only one telemetry system. This has to be confirmed though.

However, my understanding is that future 3DR firmware upgrades might bring mesh network functionalities so let's stay tuned !

I'm also looking forward to do 3DR 433MHz range tests using a larger aerial on the GCS, I can use some of my HAM radio antenna that works on the 70cm.

Hello. I have 3 modules.(all the same). One on the PC (connected by the FTDI-style pinout and USB connector), one in the Ardustation and one in the Copter.
All modules with same configuration.

You can always have one connection (Copter-----PC  or  Copter----Ardustation)

Not Ardustation and PC module running at the same time

Now we need to communicate with the ardustation the mission planner.

This one gets the data from the telemetric ardustation.

 

Exemple :

 

3DR Radio  (air)    =>  3DR Radio (sol) => Ardustation => USB PC => Mission planner.

                                                                                                    => Antenna Tracking

I think it is not possible with Atmega 328 but, if used Atmega2560, it is possible.

Because, Atmega 328 has one tx-rx port and it use for 3DR Radio.

Atmega 2560 has four tx-rx port, and it may use one port for 3DR Radio and one port for PC with FTDI.

Did you solve this. What extra gotchas did you encounter ?
