Downlink status of Sigfox Backend

  • Hi All

    I am attempting to establish two-way comms with the Sigfox backend. I am able to send bytes to the backend from my Fipy, as I can see the messages appearing in the backend. Requesting downlink messages is proving more difficult. I am using the following code, and receiving the following error message.

    As part of my troubleshooting, I have seen other users on the forum 'checking the downlink status' of the backend, and referencing screens such as this.

    Could anyone instruct me in finding this downlink status in the backend? I am aware that there is a maximum of 4 downlink messages per day in Europe, and that I may have fixed the problem already but would not be able to verify this until tomorrow. Checking the backend status in the meantime would be a big help to see if I have correctly requested a downlink message.


  • @bitvijays Excellent - That clears it up!

  • @WilkinsSq Have a look at this

    You are receiving ENETDOWN because either the value of Download link mode is None or Callback. This setting can be found in Device type>Device>Edit. If you set it to DIRECT, the Sigfox will send the message back to your device.

  • Hi @Eric73

    Thats a big help! Thanks very much. I am showing some green downlink arrows. Can I confirm, the green downlink arrows mean that the Sigfox backend has sent back messages to the device (or at least attempted to?)

    Kind Regards

  • You nedd to login in sigfox backend
    click on device
    click on your device ID (hexa decimal number )
    click on messages (left menu)
    in the message list you have up arrow for uplink message detail
    click on a down arrow for have downlink message detail
    If arrow is red there a trouble, if the arraow is green no problem at all (but perhap no data is available for your downlink).

    Note : Sigfox allow 4 downlink message by day, sending more is allowed, just there are send as "best effort policy" to your device, in france if i request more downlink it's works most of the time (specially as pycom device is tagged as devkit in sigfox backend... ;-) )
    I cannot speak for other country.
