    Eduardo,

    Ok, then it probably was a lease related issue. Do node list to see if it’s still in the db. I think you can remove them with node remove.

    Hey Jean,

    Your best bet for getting a rough roadmap is to open a support case.

    Furrukh,

    It’s currently not possible to send lora packets between Conduits.

    Hey Mark,

    If you are getting 4 values back, then you are using it correctly. They will all be zero until you do an OTA join or, if doing manual join, until the mDot receives a packet from the server.

    Eduardo,

    Look at the transmit section of this page:

    Conduit mLinux: LoRa Communication

    As noted there,

    The packet must be in JSON format and the data must be Base64 encoded

    Eduardo,

    When you changed the device address, did you do the node add command again?

    I suspect your address lease expired. After network["leasetime"] in lora-network-server.conf (minutes), the node will be purged from the DB. If the device then transmits again, the server will reject it because the address lease has expired.

    Jean,

    Ok, then I can’t think of any more obvious reasons it wouldn’t work. I suggest opening a support case (and link to this thread) for possibly more debugging or UDK replacement.

    Ok it sounds like your setup is good. Does your mDot have the programming header installed?

    Jean,

    Hmm, this is definitely not normal behavior. Is the blue PWR LED on the UDK lit?

    Have you tried a different USB port? Cable? Different computer?
    Some people have had issues where the corporate computer settings blocked USB drives, and they had to flash the mDot using a virtual machine.

    Jose,

    I suggest checking out this page which shows how to view all AT Commands:

    AT Command Getting Started Guide

    You can also download a developer guide from this page:
    http://www.multitech.net/developer/products/multiconnect-mdot/

    And the frequency band cannot be changed (from 915 to 868 or vice versa).

    Neil,

    So we are wondering if this is related to Windows 10. Everything you are doing looks correct and are the same commands we use to build on Windows 7. Do you have a Windows 7 pc to try or could you install it in a virtual machine?

    Jim,

    Ah, that is interesting. I did a quick search and it looks like this is a known issue with Express 3 which is used by the Conduit’s version of Node-RED but is fixed in Express 4. The Node-RED upgrade won’t be in the next Conduit version to be released within a month or two (Node-RED v0.11.1), but we’ll try to get NR 0.12.0 or later in the next release after that.

    Jim,

    Since it is only sampling, your best path is to create a support case where you’ll be connected to the folks who can answer your EVB questions as they may not be checking these forums 🙂

    Furrukh,

    This sounds like a bug fix we did that’ll be in the next firmware version. The bug didn’t allow sending an sms with a zero in it. Likely your inject node is sending a timestamp through the sms node (which overrides the sms node payload setting).

    Try changing the inject node to use a string without zero’s.

    Those results only indicate something isn’t configured correctly. It doesn’t mean you have bad hardware. Go ahead and open a support case and someone will help you get things set up.

    Furrukh,

    What sms content you are trying to send?

    Try sending an sms from the linux command line to rule out Node-RED interface issues. To do this, ssh into the Conduit using the same credentials as the web GUI and run this command:
    sms -vd /dev/modem_at1 send 8881231234 but replace the phone number with your own cell phone. That will open the vi editor where you can press i, type a message, press esc, then type :wq to close vim and send the message.

    Paste the output here.

    Jose,

    Alright, let’s just have you go ahead and create a support case which will make it easier to help you and send files back and forth. Use the same login information as for these forums and in the case, describe as much as possible. Put what you have tried, what works, what doesn’t, etc. Also include either the Conduit configuration files or screenshots.

    Thanks!

    Jose,

    If you can issue AT commands to the mDot, your UDK is powered properly.

    Please post the output of the AT&V command from the mDot as well as a screenshot of your Conduit’s Lora configuration.

    Jose,

    Have you established mDot to Conduit communications and vice versa? The Conduit will only transmit after downstream data is queued for a mDot and a packet is received from that mDot.

    Patrick,

    I can put you in touch with our sales engineers. Are you wanting all the Conduits to be on the same LoRa network? Are you planning on using a public network like http://thethingsnetwork.org/ or do you want to have a private network?

    When I first tried to do this, I got the same error. I then set the Conduit time to be the correct time and timezone, rebooted, and now it works properly.
