Telemetry?

[richardg6paj]

Hi,
Is it possible for the Crius board (or any other board for that matter) to tell me what mode it';s in while it';s flying. If so what do I need?
Or what do I need to do.

Regards

You can use bluetooth modules for short range stuff (20 meters or so if you are lucky) - very handy with a good smart phone. You can also use 433mhz radio modules (legally, in the uk) for longer ranges (up to a km or two with good aerials) if you have a laptop you can take with you to the field.

I don';t think the 915mhz modules are legal for use in the UK. It';s well worth checking the rules and regulations where you are before buying radio equipment on a new frequency.

The bluetooth modules are great when it works but I found them to be a lot of hassle when they didn';t. They are pretty cheap so worth a punt to see how you get one with one.

I ended up getting a 3DR clone 433mhz telemetry module which I';m very happy with, over 400m range with stock antenna, cost about £38.

For smartphone software have a look and Andropilot or Droidplanner.

Thanks for the info.
Do you have to choose what information you want or does the firmware just stream all the data out.
Not done telemetry before. I have as well as the Crius a Naza M on a f550 frame and have just been using the Flashing LED to confirm what
mode it';s in. I bought the crius and a small quad to build  and experiment (play) with and realised there was no built in confirmation as to what mode it
was in.

The firmware outputs a stream of data via bluetooth or whatever and the software on your laptop or smart phone makes sense of it and displays relevant info etc.

Have a look in the android market place for stuff associated with your flight controller and download a few examples to play with. You';ll get the idea pretty quickly.
