xbee with Mavlink 1.0

Posted by x-air71 on July 11, 2012 at 1:08pm

I have a trouble with Xbee, it happen after the last update.

On hexa, the xbee module have blue and red light switched on, trying to connect with mission planner (57K), I see the following errors:

    Hi Rick, i will try again, hopefully this evening.
    I have teamviewer installed, so no problem for this.In case I will face the same problem it could be a solution, thanks for your availability. In case I'm not able to make the air module work again could be a good solution.
    Where do you live, in order to see if it is possible to find an appropriate timing in case of need ;-)
    I'm living in Istanbul, let's say European hour + 1

    Thanks

    Just reading through your problem, I couldn't spot the obvious so I am going to ask.

    Have you unplugged the "Air" module from it's board on the Hexa and plugged it into the USB board connected to your computer to configure it with X-CTU?

    You won't be able to configure it while it is in the Hexa.

    Hi Rick, I've tried your procedure in order to unbrick the air module, but no success.
    I can read the configuration of the 'ground' one but looks like I cannot write it in the air one, or better I can write it, then I have to switch back to 9600 baud in order to read it but the parameters look different and it is not working...
    Is there any place where i could find the right firmware to upload to the air module?

    Thanks

    Hi Rick, thanks to your reply.
    I will do all the tests tomorrow (and some repair work as well.....).
    I will follow the procedure...Hope the xbee module could work again!

    Thanks again for your time!
    Let you know

    @Mike: the red light in the Air module (hexa) is always on as I connect the batteries...
    @Rick: the Air module does not have the usb connector....i guess i will need a special cable in order to use the tool X-CTU....
    In what does consist the 'unbrick' procedure? reinstalling the firmware?

    Thanks

    I believe the red LED is an RSSI indicator. It comes on whenever I open a connection to the copter.

    So in Mission Planner, when connect is selected, the Red LED comes on.

    Hi Mike, in fact I have a Window7 64bit...I will try your suggestion, hope it could work.
    One question: in the xbee module on the hexa, both blue and red light are on, I remeber the blue one but not the red one? do you know what the red led means?

    Thanks

    @Micheal, thanks for your answer...do you know what the red led means?

    to me it looks like your xbee's ant talking to each other. ie no data

    I did find issues like this on some updates under Windoze 7 

    I resolved them by resetting permissions in the Mission Planner directory.

    Now, whenever there is an update I say no, quit Mission Planner, then run it as Administrator and do the update.

    No more problems.

    Worth a try.
