    Nice one Chris :).

  • Product DEV-11168 | about 2 years ago

    If you’re using the Arduino 1.0 IDE, then after you have used it to burn the bootloader, you then load the sketch the normal way.

    Cheers Dean. I’ll give the arduino thread another week and then see if I can convince Roving Networks to fix the bug.

    The GainSpan looks interesting, although it costs twice as much and is only 802.11b.

    Is anyone else seeing this firmware crash with 2.32? I’ve posted it here: arduino.cc forums.

    Basically if you attempt to open a TCP connection and it fails, then attempt two or three more connections that work the firmware crashes and the WiFly reboots. Here’s my serial log of the crash: set ip host 192.168.1.42 AOK set ip remote 80 AOK open Connect FAILED

     lookup google.com
    google.com=74.125.237.8
     set ip host 74.125.237.8
    AOK
     open
     *OPEN*CMD
    close
    *CLOS* open
     *OPEN*CMD
    close
    Unrecoverable failure (7) Misaligned address at PC=0002fb68
    The system will be reset

    Umm, wouldn’t you just set a channel, transmit a few packets, repeat for next channel (etc)?

    Where are you stuck?

  • Product WRL-10822 | about 2 years ago

    I’ve written an Arduino library for the RN-XV. Version 0.1 is available here github/WiFlyHQ. At the moment it supports hardware and software serial interfaces, sending and recieving UDP packets, making TCP connections and sending and receiving data over the connection.

    I plan to add support for all of the RN-XV features, but if you are interested in anything specific then post a request or comment on github and I’ll work on that next.

    Cheers.

  • News - New Product Friday: Look … | about 2 years ago

    I had no problems getting three series 2 XBees to work. One is the coordinator, one is a router, and the third is and end device that sleeps for 10 minutes, wakes up and takes some measurements and sends them back to the coordinator, then sleeps again. Looks like a great mesh networking technology.

    The only nasty part was that xctu only runs on Windows so I ended up having to install Windows XP in a VM just to use it to configure the XBees.

    Awesome product. Very easy to setup and use. I’ve only tried UDP so far but the TCP and HTTP support looks easy too.

    I did have a problem when I updated to the 2.30 firmware - stopped associating with my Airport Extreme, but dropping back to 2.27 fixed the problem.

    I’m using it with an xbee shield from seeedstudio that I had for zigbee experiments.

  • Product DEV-09950 | about 3 years ago

    Yes it does. Its quite easy to do. I’ve posted details on my blog along with source code, MIDI USB device firmware for the UNO’s atmega8u2, and a sample sketch to send 5 notes to the host PC. Details here: UNO MIDI USB driver.
    Cheers,
    Darran.

    These are a lot thinner than I expected, not like normal pins. They won’t stand up to a lot of insertions and may not make good contact with the socket, I really don’t recommend them.

No public wish lists :(
